Rule 5 Draft Explained: Eligibility, Cost and Roster Rules

The Rule 5 draft is Major League Baseball's yearly mechanism for prying loose players another organization has kept in the minors. It is held every December at the Winter Meetings. A club may select a minor leaguer from any other organization provided he has been a professional for four or five seasons, depending on the age at which he signed, and has not been placed on his club's 40-man roster. The price is $100,000. The condition is the hard part: the player must stay on the selecting club's 26-man active roster for the entire following season, and if the club wants him off it, he has to be put on waivers and then offered back to his old club for $50,000.

When it works, it can change a franchise. In December 1999 the Minnesota Twins held the first pick and spent it on a pitcher named Jared Camp. The Florida Marlins, choosing second, took a 20-year-old left-hander out of the Houston Astros' system who had not yet pitched above Class A. The two clubs then swapped their selections, as they had arranged beforehand, with Florida adding $50,000 to cover what the pick had cost. The left-hander was Johan Santana. He won the American League Cy Young Award for Minnesota in 2004 and again in 2006. Outcomes like that are rare.

The Rule 5 draft in one sentence, and the numbers behind it

Each December a club can take an unprotected minor leaguer from another organization for $100,000, on condition that he stays in the majors all season.

Every clause in that sentence is a rule. "Unprotected" means left off the 40-man roster after a set number of professional seasons. "Another organization" means the draft only moves players between clubs; nobody selects his own. "Stays in the majors" means the active roster, with no trips to Triple-A and only limited shelter on the injured list. Take any one of those away and the draft stops working as intended, which is to make a club choose between promoting a player and risking him.

• 5Seasons before a player signed at 18 or younger is exposed
• 4Seasons before a player signed at 19 or older is exposed
• 26Players on the active roster he must be one of
• 90Days on the active roster required

Thresholds for the major-league phase as set by the Major League Rules and the Basic Agreement. The eligibility clocks have stood at five and four seasons since 2006.

Two parties gain from a selection and one loses. The selecting club gets a player for a sum that would not buy a week of a free-agent reliever. The player gets a big-league salary, a place on a 40-man roster and major-league service time, often years before his own club would have given him any of them. The minimum salary alone is several times what a Double-A player earns in a season. The club that loses him gets a check for $100,000 and a lesson about its roster management.

The draft has two parts with very different stakes. The major-league phase is the one described above and the one people mean when they say "the Rule 5 draft." A minor-league phase follows it the same morning, cheaper and free of conditions, and it gets its own section below.

Who is eligible for the Rule 5 draft: the four- and five-year clocks

Eligibility turns on two questions. How old was the player when he signed his first professional contract, and how many seasons have passed since.

Player	Age at signing	When he becomes eligible
International amateur signed as a teenager	Usually 16 or 17	The fifth Rule 5 draft after he signs
High school draft pick	18 or younger	The fifth Rule 5 draft after he signs
Junior college or four-year college draft pick	19 or older	The fourth Rule 5 draft after he signs
Undrafted free agent out of college	19 or older	The fourth Rule 5 draft after he signs
Any player on a 40-man roster	Not relevant	Not eligible at all

The dividing line is 18, and the rule measures age on the June 5 immediately before the signing. A player who was 18 or younger on that date gets five seasons in the minors before his club has to decide. A player who was 19 or older gets four.

The two clocks are designed to converge. A high school player drafted in one summer and a college junior drafted the next will be about the same age and will reach eligibility in the same December. For the draft of December 2025, by that arithmetic, the newly exposed group was the high school and young international class of 2021 alongside the college class of 2022. The season in which a player signs counts as his first, even if he signed in July and barely played.

What does not make a player eligible

Performance is irrelevant. A player who hits .340 in Double-A is no more eligible than one who hits .190; only the calendar and the 40-man roster matter.

Being on the 40-man roster is complete protection. That is the whole purpose of the device: the only way to shield a player whose clock has run out is to give him one of the 40 places, with the option years, the service implications and the roster squeeze that follow. The relationship between the two rosters is covered in our explainer on the 26-man and 40-man rosters.

Once a player is eligible he stays eligible. A player passed over at 22 can be taken at 23 or 24, and some of the more useful selections have been men in their third year of exposure who finally figured something out. Where each of those minor-league levels sits is set out in our guide to minor league baseball from the complex leagues to Triple-A.

The November protection deadline and the 40-man roster crunch

The decisions that shape a Rule 5 draft are made about three weeks before it, on a weekday evening in mid-to-late November. That is the deadline for clubs to set their 40-man rosters ahead of the draft. Any eligible player not added by then is available to the other 29 organizations.

For a club with a deep farm system this is one of the harder days of the year. Suppose it has 37 players on the 40-man roster and seven eligible prospects it would like to keep. Three can be added. To protect the other four, four players already on the roster have to go, by trade, by release or by being designated for assignment, and each of them was on the roster for a reason.

So the days before the deadline produce a recognizable flurry: small trades in which a club with too many eligible prospects sends one to a club with roster room, veterans cut loose, fringe relievers placed on waivers. Clubs with a surplus would rather get a low-level prospect back than lose a player for the $100,000 fee.

1. 1Protection deadlineIn November each club finalizes its 40-man roster. Eligible players left off it are exposed.
2. 2Draft dayIn December, at the Winter Meetings, clubs select in reverse order of the previous season's standings.
3. 3Onto the 40-manA selected player goes straight onto his new club's 40-man roster and the $100,000 fee is paid.
4. 4Spring trainingHe competes for a job. The club must decide by Opening Day whether it can carry him.
5. 5Opening DayIf he makes the 26-man active roster, the season-long clock starts. If not, he goes on waivers and is offered back.
6. 6Regular seasonHe cannot be optioned to the minors. He must log at least 90 days on the active roster.
7. 7Season's endHaving met the conditions, he becomes an ordinary member of the organization and can be optioned the next year.

The usual sequence for a player selected in the major-league phase. Exact dates move from year to year; the order does not.

The calculation a front office makes

Protecting a player is not free. A place on the 40-man starts his option clock and narrows the club's flexibility for the whole of the next season. So the question asked in November is not "is this player good" but "would another club keep him in the majors for a full year." A 21-year-old shortstop in Class A with a high ceiling may be the better prospect and the safer one to leave exposed, because no club can hide a hitter that raw on a big-league bench for six months. A 24-year-old reliever in Triple-A with a 97 mile-an-hour fastball is the lesser prospect and far more likely to be taken.

Clubs get this wrong in both directions every year. They protect players who never reach the majors, and they expose players who are taken and stick. The second kind of mistake is the one that gets remembered.

Draft day mechanics: reverse order, an open roster spot, and a lot of passing

The draft itself takes a few minutes. It is held as the Winter Meetings are winding up, clubs are called in reverse order of the previous season's winning percentage, and each one either names a player or passes.

One precondition thins the field before it starts. A club may select only if it has an open place on its 40-man roster, because the player goes onto that roster immediately. A club at 40 cannot pick. Front offices that intend to draft will leave a place open in November for the purpose; those that filled the roster protecting their own prospects are spectators.

The rounds continue as long as anyone is still selecting. A club can take a second or third player in later rounds if it has the roster room, though it is unusual to see more than a few clubs go beyond one.

The speed of the session hides what a selection commits a club to. In one sentence read into a microphone, a front office has added a player to its 40-man roster, spent $100,000, and in effect promised an Opening Day job to someone its manager may never have seen play.

Most clubs pass, and the reason is the cost of carrying the player, not the cost of buying him. A contender expects to use all 26 places on its active roster to win games. Giving one of them, for six months, to a player who was in Double-A last year means playing short. In the years since the fee was raised, the major-league phase has usually produced somewhere between ten and twenty selections across all 30 clubs. The 2021 major-league phase was not held at all, a casualty of the owners' lockout that winter, although the minor-league phase went ahead.

The order matters less than in the amateur draft, because clubs are not choosing among the same handful of names. Each has its own short list built around a specific need, usually a bullpen arm or a bench role. Still, the first two or three picks are worth having, and they are sometimes traded for.

The condition that makes it hard: a full season on the 26-man roster

Everything difficult about the Rule 5 draft is contained in what happens after it.

A player selected in the major-league phase must remain on the selecting club's 26-man active roster for the entire following regular season. He cannot be optioned to the minors. He cannot be outrighted there either, not without the steps described below. For a healthy player the choice is binary: he is in the big-league dugout, or the club is in the process of giving him up.

Rule	Ordinary 40-man player	Rule 5 pick in his first season
Can be optioned to the minors	Yes, if he has option years left	No
Can be placed on the injured list	Yes	Yes, but the time does not count toward his 90 days
Can be traded	Yes	Yes, and the restrictions go with him
Can be sent outright to the minors	After clearing waivers	Only after clearing waivers and being declined by his old club
Cost to the club if it gives up on him	None beyond his salary	Half the draft fee is refunded if his old club takes him back

1. 1DecisionThe selecting club concludes it cannot keep the player on its 26-man active roster.
2. 2WaiversHe is placed on outright waivers. Any of the other clubs may claim him.
3. 3ClaimedA claiming club pays the waiver price and inherits every Rule 5 restriction for the rest of the season.
4. 4UnclaimedHe is offered back to the organization he was drafted from for $50,000.
5. 5Old club acceptsHe returns to his original organization, which may send him to the minors without adding him to its 40-man roster.
6. 6Old club declinesThe selecting club may then outright him to its own minor-league system and keep him.

The return procedure under Rule 5 for a major-league phase selection who has not yet satisfied the season-long roster condition.

The last step is the least known and it produced one of the draft's better stories. Shane Victorino was a Rule 5 pick twice. San Diego took him from the Dodgers after the 2002 season and returned him. Philadelphia took him from the Dodgers again two years later, decided in spring training that he could not make the club, put him through waivers and offered him back. Los Angeles said no. So the Phillies kept him, sent him to Triple-A, and by 2008 he was the center fielder on a World Series winner.

The waiver step has teeth too. Jose Bautista was selected by Baltimore from Pittsburgh in the 2003 draft and spent 2004 passing through five organizations, claimed and traded and traded again, with the Rule 5 conditions attached to him at every stop. He ended the year back with the Pirates. The mechanics of claims and priority are in our explainer on how waivers and options work.

The injured list and the 90-day requirement

The obvious way around the rule would be to select a promising player, discover a sore shoulder in March, and leave him on the injured list until October. The rules anticipated it.

A Rule 5 pick may go on the injured list like anyone else. Time spent there does not count as time on the active roster, and the rule requires at least 90 days on the active roster before the restrictions lift. A player who finishes his first season short of 90 active days carries the restrictions into the next one. He must open that season on the active roster and stay there until the balance is made up.

Anthony Santander is the standard example. Baltimore selected him from Cleveland in December 2016, and injuries kept him on the shelf for most of 2017. He did not reach 90 days. The Orioles therefore had to carry him on the big-league roster at the start of 2018 for the remaining weeks before they could send him to the minors for the development time he plainly needed. They did, and he later became one of the more productive hitters the draft has turned up in the past decade.

Why the 90 days are there

The requirement is aimed at the phantom injury. A club with a talented but unready pick has every incentive to find something wrong with him, and the league has no practical way to audit every sore elbow. Ninety active days is a blunt answer: the club can use the injured list, but it cannot use it to avoid the test the draft was designed to set.

Ninety days is roughly half of a regular season, which runs a little over six months. A pick who is hurt in April and returns in July can still get there. One who has surgery in spring training cannot, and the club must decide whether it is willing to repeat the exercise a year later. The different injured lists, and what the 60-day version does for a 40-man roster, are explained in our guide to MLB injured list rules.

A serious injury to a Rule 5 pick is therefore a strange piece of luck for the club. It keeps the player without having to play him, at the price of a roster place the following spring.

The minor-league phase: a cheaper round with no strings attached

When the major-league phase ends, a second draft begins in the same room. This is the Triple-A phase, and it runs on different rules.

Each organization files reserve lists for its minor-league affiliates as well as its 40-man roster, and the Triple-A list has a fixed limit. A player who is eligible by the calendar and is on neither the 40-man roster nor the Triple-A reserve list can be selected in the minor-league phase by any club with room on its own Triple-A list.

The fee is $24,000. Nothing is owed after that. The player does not have to be kept at any level, does not have to be offered back, and joins his new organization as an ordinary minor leaguer. A club takes a 25-year-old catcher to fill out its Double-A roster, or a left-hander with one good pitch, and both sides move on.

Fee	$100,000	$24,000

Roster the player joins	The selecting club's 40-man	The selecting club's Triple-A reserve list
Must stay in the majors	Yes, all season	No

There used to be a third tier, a Double-A phase with a fee of $4,000, which was dropped starting with the 2022 draft. The Triple-A fee doubled at the same time, from $12,000.

More players usually change hands in this phase than in the first one, and almost none of them are heard of again. Almost. Justin Bour, taken by the Marlins from the Cubs in the minor-league phase in 2013, became a regular first baseman in the majors. Finds like him are the reason clubs keep scouts on the assignment. A team gets a few such picks a year for the price of a used car, and one in a great many turns into something.

Trades around the draft: picks sold within minutes and rights bought back

A Rule 5 selection can be traded, and a good many are dealt before the session has ended. The Santana swap is the model. Minnesota wanted Santana and Florida wanted Camp, but draft order would have had each club take the other's target, so they picked for one another and exchanged. Josh Hamilton's route to the majors ran the same way. The Chicago Cubs selected him from Tampa Bay with the third pick in December 2006 and sold him at once to Cincinnati, which had arranged the whole thing and paid for it.

Why not simply trade up? In practice what clubs trade is the player, after the pick. A club lower in the order that fears its man will be gone finds a partner near the top, agrees a price in cash or a minor leaguer, and waits for the announcement.

The restrictions travel with the player

Whoever ends up with a Rule 5 pick holds him on Rule 5 terms. Cincinnati had to keep Hamilton on its roster all of 2007 exactly as the Cubs would have. A club that claims a pick on waivers in May is bound for the rest of the year. Bautista's 2004 is what the rule looks like when nobody can quite commit.

That differs from an ordinary trade in one useful respect: the calendar does not interfere much. A Rule 5 pick is on a 40-man roster, so during the season he is subject to the same cutoff as everyone else, described in our guide to MLB trade deadline rules, but nearly all the dealing around these players happens in December and March, when the market is open.

Buying the rights outright

One trade makes the restrictions disappear. If the selecting club and the player's original club agree a deal for him, the selecting club acquires his full rights, the Rule 5 conditions fall away, and he can be optioned to the minors like any other young player.

Seattle did this with R.A. Dickey in the spring of 2008. The Mariners had taken the knuckleballer from Minnesota in the draft that winter, did not have a place for him on the Opening Day roster, and sent the Twins a minor-league catcher so they could keep him and start him in Triple-A. The original club has the leverage in these talks, since its alternative is to pay $50,000 and get its player back, and the price is set accordingly. It is usually modest. A club that left a player unprotected has already told the market what it thinks he is worth.

Who actually gets taken, and which clubs can afford to carry them

Look down the list of selections in any December and two types recur.

The first is the reliever with one loud tool: a fastball in the upper nineties, a slider nobody in Double-A could hit, and command that comes and goes. He is the easiest player to carry. A big-league bullpen has eight places, the last of them belongs to a pitcher who works in games already decided, and a manager can limit a raw arm to those innings for months. Our guide to bullpen roles from closer to long man describes the job a Rule 5 reliever is usually given. It is the one at the bottom.

The second is the athletic position player from the low minors, a runner and defender whose bat is two years away. He survives as a pinch-runner and late-inning replacement, and he hits .190 in 150 plate appearances while the club waits. Scouts grade such players on the tools described in our guide to the five-tool player and the 20-80 scale, and a Rule 5 selection of this kind is a bet on the grades over the statistics.

Starting pitchers and everyday hitters are taken far less often. Both need regular work to develop, and the big-league roster of a team trying to win cannot offer it.

Why rebuilding clubs do most of the keeping

A team that expects to lose 95 games has a use for its 26th roster place that a contender does not. It can treat that place as a development slot and accept the losses that come with it. The San Diego Padres carried three Rule 5 picks through the whole of the 2017 season, none of whom had played above Class A, because the club was at the bottom of a rebuild and the wins were not the point. Kansas City found a place in its 2018 rotation for Brad Keller, selected by Cincinnati from Arizona the previous December and traded to the Royals the same day, in a season in which the club lost more than 100 games.

There is a cost even then. A Rule 5 pick thrown into the majors early loses the at-bats or innings he would have had in the minors, and a year spent on a big-league bench can set a hitter back. Clubs know this and take the player anyway, on the reasoning that a year of slow development for someone they now own beats a year of fast development for someone they do not. Spring training is where that judgment is tested, and the way clubs sort out the last roster places in March is described in our guide to MLB spring training.

A fair share of each December's selections are back with their original organizations before the summer.

The Rule 5 picks that worked: Clemente, Santana, Hamilton and the rest

The list of successes is short enough to memorize and good enough to keep every club looking.

Draft	Player	Selected by	Taken from
1954	Roberto Clemente	Pittsburgh Pirates	Brooklyn Dodgers
1980	George Bell	Toronto Blue Jays	Philadelphia Phillies
1999	Johan Santana	Florida Marlins, traded to Minnesota	Houston Astros
2004	Shane Victorino	Philadelphia Phillies	Los Angeles Dodgers
2005	Dan Uggla	Florida Marlins	Arizona Diamondbacks
2006	Josh Hamilton	Chicago Cubs, sold to Cincinnati	Tampa Bay Devil Rays
2006	Joakim Soria	Kansas City Royals	San Diego Padres

Roberto Clemente is the greatest of them and the product of a rule that no longer exists. The Dodgers signed him in 1954 for a bonus large enough to trigger that era's bonus rule, which required a club to keep such a player in the majors or leave him open to the draft. Brooklyn sent him to its Montreal farm club and played him sparingly, in what has always been read as an attempt to hide him. It failed. Pittsburgh had the worst record in the league and the first selection that November, and its general manager was Branch Rickey, who had run the Dodgers a few years earlier. Clemente collected 3,000 hits for the Pirates and went into the Hall of Fame in 1973.

George Bell was 21 when Toronto took him from the Phillies in 1980. Seven years later he was the American League's Most Valuable Player.

Dan Uggla had spent five seasons in Arizona's system without getting past Double-A. Florida made him its second baseman in 2006, and he hit 27 home runs and was an All-Star as a rookie.

Josh Hamilton had been the first overall pick in the 1999 amateur draft and had hardly played in three years when the Reds engineered his selection. He was traded to Texas after one season and was the American League MVP in 2010.

Joakim Soria had been pitching in the Mexican League while under contract to San Diego. Kansas City took him in the same 2006 draft that produced Hamilton and got a closer who went on to make two All-Star teams.

More recent drafts have yielded useful players without matching that group: Ryan Pressly, Odubel Herrera, Mark Canha, Santander, Keller, Garrett Whitlock. The pattern in the table is hard to miss. Its last entries are from 2006, the year the eligibility clocks were lengthened.

Why it is called the Rule 5 draft

The name is a filing reference. Baseball's player transactions are governed by a document called the Major League Rules, a set of numbered rules agreed among the clubs and administered by the Commissioner's Office. Rule 5 of that document is headed "Annual Selection of Players." The draft is the selection that rule describes.

The amateur draft has the same kind of name for the same reason. It is set out in Rule 4, headed "First-Year Player Draft," and inside the industry it is routinely called the Rule 4 draft to distinguish it from this one.

Feature	Rule 4 draft	Rule 5 draft
Who is selected	Amateurs from high schools and colleges	Professionals already under contract to another club
When it is held	July, during All-Star week	December, at the Winter Meetings
Length	A fixed number of rounds	Until every club has passed
What a pick costs	A signing bonus negotiated with the player	A flat fee paid to the club that loses him
Roster consequence	None; the player starts in the minors	The player must stay in the majors all season

The numbering accounts for other scraps of front-office jargon as well. The same document's provisions on waivers, optional assignments and reserve lists are cited by rule number inside the game, though only the two drafts have escaped into public use.

The two drafts have almost nothing in common beyond the word. One brings players into professional baseball. The other redistributes players already in it. A fan who follows the NFL will find no real equivalent there. The nearest thing by name, covered in our guide to the NFL supplemental draft, is an entry draft for late-eligible amateurs and works on a different principle altogether.

On the spelling: "Rule V" turns up in print now and then, but the league's own documents use the numeral 5.

Why the draft exists, and how the eligibility clock was lengthened in 2006

Organized baseball has had some form of draft of minor-league players since the 1890s, long before the amateur draft and before the farm system. In the early version, independent minor-league clubs owned their players, and the draft let a higher league buy a player at a fixed price so that he could not be held back by an owner who preferred to keep a gate attraction.

The problem changed shape in the 1920s and 1930s, when Branch Rickey built the St. Louis Cardinals a chain of minor-league clubs and other organizations copied him. Now the club holding a player down was his own parent club. A wealthy organization could sign hundreds of players, control them for years, and promote a handful. Commissioner Kenesaw Mountain Landis loathed the arrangement and twice acted against it, declaring more than 70 Cardinals farmhands free agents in 1938 and about 90 Detroit Tigers minor leaguers in 1940. Those were one-off rulings. The Rule 5 draft is the standing remedy: a recurring test that asks every organization, every winter, whether the players it has had for four or five years are worth a roster place.

It does that job imperfectly, and by design it has done it less since 2006. Until then the clocks were a year shorter, four seasons for players signed at 18 or younger and three for those signed at 19 or older. The Basic Agreement reached in 2006 added a year to each.

The clubs' argument was that three and four years were not enough to evaluate a teenager, and that the short clock forced premature 40-man decisions. Both points are fair. The effect, though, was to hand organizations an extra year of control over every minor leaguer and to drain the draft of its best material. A player good enough to become a star has usually shown it by his fifth professional season and been protected. The change took effect at once, exempting many players from the 2006 draft itself, and it is the likeliest reason the table of famous picks stops in 2006.

What remains is a market for the 26th man. That is still worth something to the player concerned, who gets a big-league salary and a head start on the service clock that leads eventually to arbitration and the open market, the route described in our guide to how MLB free agency works. And every few years a Whitlock or a Santander turns up to remind front offices why they keep a 40-man place open in November. The rest of our coverage of the sport's rules and roster machinery is gathered in the baseball hub.
