Foul Tip Rule: How a Foul Tip Differs From a Foul Ball
The foul tip rule in MLB explained: why a tip the catcher holds is a live strike on any count, and why the same nick is only a foul ball if it drops.

A fastball at the letters ticks the top of the bat, changes direction by an inch and smacks into the catcher's mitt. The plate umpire brushes the fingers of one hand across the back of the other and then punches the air. Strike. Nobody shouts "foul," and the runner who broke from first on the pitch keeps going.
That is a foul tip as Major League Baseball defines it. In the Official Baseball Rules, a foul tip is a batted ball that goes sharp and direct from the bat to the catcher and is legally caught. It is always a strike, including strike three, and the ball stays in play. If the catcher does not hold it, it was never a foul tip at all. It is an ordinary foul ball: dead the moment it hits the ground, a strike only if the batter had fewer than two, and no use to a runner trying to steal.
What is a foul tip in baseball? The definition, clause by clause
The entry sits in the Definitions of Terms and runs two sentences. The first says what a foul tip is: a batted ball that goes sharp and direct from the bat to the catcher and is legally caught. The second says what follows: it is not a foul tip unless caught, and any foul tip that is caught is a strike, and the ball is in play.
Each phrase is a condition, and a play has to meet all of them.
"Batted ball" means the bat touched it. A pitch that glances off the hitter's knuckles or his sleeve without meeting wood is not batted, and a different set of rules decides whether he swung or was hit.
"Sharp and direct" is the test that separates a tip from a pop-up. The ball has to go more or less straight back, on the line it was already traveling, with no arc the eye can pick up.
"To the catcher" limits the play to one fielder. The definition names the catcher and no one else.
"Legally caught" means held securely in the hand or the mitt before the ball touches the ground. A ball that wedges in the chest protector or the mask and stays there has lodged in the equipment, and the rulebook does not treat that as a catch.
Then the consequences, which are what surprise people. A caught tip is a strike. Not a foul with strike-like properties, a strike, with everything that comes with one. And the ball is in play, which is the reverse of what the word "foul" means everywhere else in the sport.
The name is the problem. Announcers say "foul tip" for any ball that nicks the bat and goes backward, including the ones that rattle off the backstop. By the book most of those are foul balls. The rule is easier to follow if you treat "foul tip" as the name of a kind of strike that happens to involve the bat.
Caught or not caught: foul tip vs foul ball on every count
Everything turns on what the catcher does in the next quarter of a second. Same pitch, same swing, same faint click off the bat. If the ball stays in the mitt, one set of results applies. If it reaches the dirt, the other does.
| Count before the pitch | Catcher holds the tip | Tip reaches the ground |
|---|---|---|
| No strikes | Strike one, ball live | Strike one, ball dead |
| One strike | Strike two, ball live | Strike two, ball dead |
| Two strikes | Strike three, batter out, ball live | Foul ball, count unchanged, ball dead |
| Any count, runner stealing | Steal or caught stealing stands | Runner returns to his base |
| Any count, runner picked off after the pitch | Out stands | No play, ball was dead |
On the first two counts the scoreboard cannot tell the difference. A strike is added either way. What changes is the status of the ball, and that only matters when someone is on base.
With two strikes the gap is as wide as the sport allows. One outcome is a strikeout. The other is a pitch that might as well not have been thrown, and the batter gets another.
Catchers are aware of this in a way few fans are. The receiving skills measured in our piece on catcher framing are about presenting a pitch the batter took. Holding a tip is a rawer skill: the ball arrives a few inches from where the mitt was set, a few hundredths of a second after the bat redirected it, and the catcher either closes on it by reflex or he does not.
The broader fair-or-foul framework, including what an uncaught foul does to the count and the runners, is covered in our guide to foul ball rules.
Foul tip with two strikes: why it is strike three
An ordinary foul with two strikes is free because the rulebook's definition of a strike says so. A pitch fouled by the batter is a strike only "when he has less than two strikes." The definition then lists the foul tip as its own item, a pitch that "becomes a foul tip," with no qualifier about the count attached. A caught tip is a strike on 0-0 and a strike on 0-2 for the same reason a swing and a miss is.
The reasoning behind the difference is about what the batter achieved. When a hitter fouls a two-strike pitch into the seats, he made contact solid enough to send the ball somewhere, and the rule rewards the contact by letting him continue. When he nicks one into the mitt, the ball ended up exactly where it would have if he had missed. The pitcher beat him. The catcher did his part. Calling that anything other than strike three would hand the hitter a reprieve for the faintest contact a bat can make.
It also keeps the rule honest at the margins. If a held tip with two strikes were merely a foul, umpires would have to decide on every swinging third strike whether the bat had grazed the ball, and each of those calls would decide an at-bat. Under the rule as written the call matters only if the catcher drops the ball.
The two-strike bunt sits next to it
A bunt has its own third-strike provision. Rule 5.09(a)(4) puts the batter out when he bunts foul on the third strike, wherever the ball goes. So a two-strike bunt attempt that is tipped back has no good outcome for the hitter: held by the catcher it is a foul tip and strike three with the ball live, and dropped it is a foul bunt and strike three with the ball dead.
A full swing leaves the door open if the catcher cannot hang on. A bunt does not.
Sharp and direct, or a pop-up the catcher happens to catch
The same catcher catching the same batted ball can produce two different rulings depending on the path it took to reach him.
A ball that goes straight back into the mitt is a foul tip and a strike. A ball that leaves the bat with a visible arc, rising even a couple of feet before the catcher gloves it, is a foul fly. A foul fly caught is an out, on any count, and it is not a strikeout. On 0-0 the difference is between strike one and an out. That is a large swing for a few inches of trajectory.
The rulebook gives no height in feet or inches. Nineteenth-century versions of the rule tried to, describing a tip as a ball that did not rise above the batter's head, and the modern text dropped the measurement in favor of two adjectives. Umpires are left to judge, and the working test most of them describe is about the catcher: did he receive the ball where his mitt already was, or did he have time to see a new flight and go get it. If the catcher reacted to a ball in the air, it was a fly.
- ContactDid the pitch touch the bat? If it did not, this is a swing and a miss or a taken pitch, and the foul tip rule is not involved.
- FlightDid the ball go sharp and direct to the catcher? If it rose with a visible arc, it is a foul fly, and a catch is an out on any count.
- First touchDid it reach the catcher before touching the ground, the batter or the umpire? If something else got there first, it is a foul ball.
- CatchDid the catcher secure it in his hand or mitt before it reached the ground? If so, it is a foul tip: strike, ball in play.
- DropIf he did not hold it, it is a foul ball: dead, runners return, and a strike only with fewer than two.
The questions a plate umpire works through under the foul tip definition in the Official Baseball Rules. The order matters, because the first answer that takes a play out of the definition ends the inquiry.
The runners feel the distinction as well. On a caught foul fly they are subject to the retouch rule and have to be on their base when the catch is made, or get back to it, as on any fly ball; our page on tagging up explains that obligation. On a foul tip there is nothing to retouch, because a strike is not a catch in that sense.
Which produces an oddity. A catcher who snags a tiny pop-up eighteen inches above his mask with a runner stealing has an out at the plate and a runner caught well off first base. The same ball six inches lower and straighter is a strike and a stolen base.
A live ball behind the plate: can you steal on a foul tip?
Yes, and a runner who is already moving should not slow down.
The definition ends with the words "the ball is in play," and that changes what the catcher is holding. After an uncaught foul he has a dead ball and nothing to do with it. After a foul tip he has a live one, and whatever was happening on the bases when the pitch was thrown is still happening.
So a runner who broke for second keeps running, and the catcher may come up throwing at once. If the runner beats the throw he has a stolen base. If he does not, he is caught stealing. With two strikes on the hitter, a tip held and a throw that beats the runner is a strikeout and a caught stealing on one pitch, the double play scorers call a strike-'em-out, throw-'em-out.
No runner has to go back. That is the most common misunderstanding of the rule, and it comes from the word "caught." A caught fly ball triggers the obligation to retouch. A foul tip is a strike, so there is no base to go back to and no appeal for leaving early.
What a drop takes away
The other branch can cost the defense an out it had already made. If the catcher gloves a tip, starts his throw and the ball squirts free and hits the dirt before he has control of it, the play is a foul ball. It was dead from the moment it touched the ground. A runner thrown out at second on the continuation goes back to first, because there was no live ball to throw.
It can cut the other way. A runner who had the base stolen easily is sent back by a dropped tip, and with fewer than two strikes the batter is charged the same strike either way. In theory a catcher would rather drop that ball than hold it. In practice nobody decides anything in the time a tipped fastball takes to arrive.
Everything else that can happen on a live pitch can happen on a foul tip. The batter can be called for interfering with the throw. The catcher can throw behind a runner at first. A runner on third may break for the plate. The hitter is the only person for whom the play is over.
The 2020 rewrite that removed the glove-first requirement
For most of the modern era the rule was narrower than the one above and a good deal harder to umpire.
Until baseball's rules committee rewrote it in 2020, the definition described a ball going sharp and direct from the bat "to the catcher's hands." It also carried a third sentence, since deleted: it was not a catch if it was a rebound, unless the ball had first touched the catcher's glove or hand. Umpire references do not agree on which printing first carried the new text, some citing the 2020 book and others the 2021 edition. The 2019 rulebook has the old wording and the 2021 rulebook the new.
Read together, those two pieces made the first thing the ball touched decisive. A tip that went bat, mitt, chest protector and was then trapped against the body was a foul tip. A tip that went bat, mask, mitt was not. It had touched equipment before it touched a hand, so even though the catcher ended up holding a ball that had never been near the ground, the ruling was a foul ball. Dead ball, runners back, and with two strikes the batter stayed alive.
The plays it produced were the kind that make a rule look silly. A ball would tick the bat, carom off the catcher's shoulder or the bars of his mask, and drop into his waiting glove, and the plate umpire, who was standing behind all of it, was expected to know whether leather or steel had been touched first. He usually could not. Nobody could at that speed. And the answer decided whether a hitter had struck out.
The new text made two changes. "To the catcher's hands" became "to the catcher," and the sentence about rebounds was removed. The effect is that any part of the catcher will do. A ball that goes sharp and direct from the bat to his mask, his chest, his shin guard or his bare forearm and is then secured in his hand or mitt before it reaches the ground is a foul tip.
| The tipped ball's path | Before the rewrite | Since the rewrite |
|---|---|---|
| Bat, mitt, held | Foul tip | Foul tip |
| Bat, mitt, chest protector, then secured | Foul tip | Foul tip |
| Bat, mask, then caught in the mitt | Foul ball | Foul tip |
| Bat, chest protector, then caught in the mitt | Foul ball | Foul tip |
| Bat, mitt, ground | Foul ball | Foul ball |
| Bat, umpire, then caught by the catcher | Foul ball | Foul ball |
It was the right change, and an unusual one for baseball, a rule made shorter. The old first-touch test asked an official to see something that could not be seen and attached an at-bat to his guess. The new one asks only whether the catcher caught the ball.
One caution for anyone who plays or umpires below the professional level. The college and high school rulebooks define the foul tip in their own words, and the first-touch question is the place where their wording has differed from the professional rule. The NCAA took up the professional wording soon after the change. The National Federation of State High School Associations did not follow at the time, so for a while a tip caught off the mask was a strike in a college game and a foul ball in a high school one. Both bodies revise their books on their own schedules, so the edition in force is the one to read.
What can never be a foul tip
The definition excludes more than it includes. Four things take a tipped ball out of it for good.
The ground. A ball that touches the dirt at any point before the catcher has secured it is a foul ball. That includes the short hop the catcher picks cleanly, the one that looks like a catch from the upper deck and from the dugout. It includes a ball that hits the mitt, pops out and lands.
The batter. A tipped ball that strikes the hitter's body or his back leg before the catcher gets it is a foul ball, and the play is dead when it hits him.
The umpire. A ball that glances off the plate umpire's mask or chest and is then caught by the catcher is not legally caught. The rulebook says so directly in its discussion of what a legal catch is. It is a foul.
A drop. The second sentence of the definition is blunt: it is not a foul tip unless caught.
That last point closes off a question that comes up every season. With two strikes, a hitter tips a pitch, the catcher cannot hold it, and the ball rolls ten feet away. Can the batter run to first? He cannot. The uncaught third strike rule applies when a third strike is not caught, and a tipped ball that reaches the ground is not a strike at all on that count. It is a foul ball, play is dead, and the hitter steps back in. The conditions under which a batter may run are laid out in our guide to the dropped third strike rule.
So a two-strike tip has exactly two endings. Held, the batter is out and cannot run. Dropped, he is still batting and cannot run. There is no third branch in which a tipped ball becomes a race to first base.
One more case causes confusion: the bat hitting the mitt. A catcher who reaches forward and has his glove clipped by the swing has not been involved in a tip of any kind. That is catcher's interference, and the batter is awarded first base unless his manager prefers the result of the play. The sound is similar. The ruling could not be more different.
How the plate umpire judges it and signals it
He is working with three clues, none of them reliable alone.
The first is sound. A tip makes a tick or a click that is distinct from the pop of a ball hitting leather, and it is usually the first cue he gets. In a full ballpark it can be lost entirely, and a bat that clips the catcher's mitt or a pitch that skims the dirt can make a noise close enough to fool anyone.
The second is the ball's path. A tipped pitch changes direction slightly, and the catcher's glove jumps to follow it. An umpire set up in the slot between the catcher and the batter has the best view on the field of that deflection. He has the worst view of what happens next, because the catcher's body is between him and the mitt.
The third is the catcher. A glove that stabs downward and comes up with the ball tells the umpire there was a change in flight. It does not tell him whether the ball touched the dirt first.
The signal
A foul tip gets a two-part signal and no call of "foul." The plate umpire brushes the fingers of one hand across the back of the other, usually up near his chest or over his head where the dugouts and the base umpires can see it, and then gives his normal strike signal. The brush says the bat touched the ball. The strike signal says the catcher held it. Shouting "foul" would tell everyone the ball was dead, and it is not.
When the ball was not held, the mechanic is the ordinary one for a foul: both arms up and a loud call, which stops any runner.
The argument
Nearly every dispute is about the dirt. The catcher comes up showing the ball in his mitt, the hitter insists it bounced, and the plate umpire has to decide something that happened behind a crouching body. He may ask a base umpire for help, and with two strikes it is worth asking, since the answer is the difference between a strikeout and a live at-bat.
What he cannot do is go to the monitor. MLB's replay regulations list the calls a manager may challenge, and whether a pitch was tipped, or whether the catcher held a tip cleanly, is not among them. The ball-strike challenge system does not reach it either. That system, described in our explainer on the automated ball-strike system, checks the location of pitches the batter took, and a foul tip by definition involves a swing or at least contact. Whether a batter offered at a pitch is a separate judgment again, covered on our check swing rule page.
Foul tip or swing and miss on strike three
When the catcher holds the ball, it makes no difference whether the bat touched it. The batter is out on strikes either way, the pitcher gets the strikeout, and the ball is live. The umpire's brush of the hand is a courtesy to the scorer and to nobody else.
When the catcher does not hold it, the question of contact decides everything.
| Two-strike pitch | Catcher holds it | Catcher does not hold it |
|---|---|---|
| Swing and a clean miss | Strikeout, ball live | Uncaught third strike: the batter may run if first base is open or there are two outs |
| Swing that tips the ball | Strikeout on a foul tip, ball live | Foul ball, count stays at two strikes, at-bat continues |
| Called third strike, no swing | Strikeout, ball live | Uncaught third strike, same conditions as a miss |
| Bunt attempt that tips the ball | Strikeout on a foul tip, ball live | Strikeout on a foul bunt, ball dead |
Look at the right-hand column. A slider in the dirt gets swung at and skips to the backstop. If the hitter missed it, he has struck out, but he is also a runner, and so is everyone else on base. If he got a piece of it, the ball is dead, nobody goes anywhere, and he is still at the plate with two strikes.
Which ruling each side wants depends on the situation, and that is what makes these arguments odd to watch. A batter with first base open and a ball rolling to the screen may be better off having missed. A batter whose catcher smothered the ball at his feet and is about to tag him would much rather have fouled it, and will tell the umpire so with great sincerity. The defense's interest flips in the same way. Sometimes a catcher who has just blocked a pitch tags the hitter and throws to first anyway, for insurance, before anyone knows what the call is.
The practical advice to players is the same at every level. On a two-strike pitch that ends up on the ground, the batter runs and the catcher finishes the play, and they let the umpire sort out what it was.
What foul tips cost catchers
The rule's tidy language hides a blunt fact. The ball in question is traveling at something close to pitch speed, it has just changed direction, and the catcher's face is about two feet behind the point of contact. A tip that does not find the mitt often finds the mask.
Catchers absorb these blows many times a season, and for most of the sport's history they were shaken off. That changed formally in 2011, when MLB and the players' union adopted a concussion policy. It introduced baseline neurological testing in spring training, required an evaluation after any suspected head injury, and made a player's return subject to clearance from MLB's medical director. It also created a seven-day list for concussions, shorter than the standard list of the time, so that a club would not be tempted to keep a symptomatic player active to avoid losing him for two weeks. The mechanics of that list and the others are in our guide to MLB's injured list rules.
The seven-day list applies to every position. Catchers have the most reason to know it exists: published research on concussions in the major leagues has found that catchers sustain them at a higher rate than other position players, with foul balls off the mask among the most common causes. Plate umpires, who stand directly behind the catcher, take the same hits.
The mask
Equipment has been the main line of defense. On September 13, 1996, Charlie O'Brien of the Toronto Blue Jays became the first big league catcher to wear a hockey-style mask in a game, a one-piece shell modeled on a goaltender's that covers the top and sides of the head. Within a decade it was common.
Whether it is safer than the traditional two-piece design, a cage worn over a skullcap, has never been settled to everyone's satisfaction. The argument for the traditional mask is that it is knocked off by a direct hit and carries some of the energy away with it. The argument for the hockey style is coverage. Catchers have gone back and forth, manufacturers have added padding systems and sprung cages to both designs, and it would be overstating the evidence to say one has won.
The stance
Catching has changed shape in the last several years, with most receivers now setting up on one knee. The change was made for receiving low pitches, not for safety. Its effect on blows to the head is not something anyone can state with confidence, though a lower target does change where a deflected ball is likely to go. It is a fair example of how little of the catcher's exposure the rules can do anything about. No wording in the rulebook moves his head.
Where the rule came from: when a caught tip was an out
- The early gameAny foul ball caught by a fielder retired the batter, and catchers stood well back of the plate to take pitches on the bounce.
- The catcher moves upMasks, mitts and chest protectors let catchers crouch directly behind the hitter, and tips caught off the bat became a steady supply of outs.
- 1889The rules separated the foul tip from other foul hits, and a tip caught by the catcher close behind the plate no longer put the batter out.
- 1895A tip held by the catcher became a strike, which gave the pitcher credit without awarding an out.
- 1901 and 1903The foul-strike rule made uncaught fouls strikes up to two, leaving the caught tip as the one foul that could be strike three on a swing.
- 2020The first-touch requirement was deleted, so a tip off any part of the catcher counts if he secures it before it reaches the ground.
The main stages in the professional rule, drawn from the nineteenth-century rule changes and the current Official Baseball Rules. Dates for the early stages are those usually given by rules historians.
The oldest version of the rule had no subtlety. In the amateur game of the 1850s and 1860s a foul ball caught by a fielder was an out, and for many years one caught on the first bounce was an out too. A ball ticked backward and held by the catcher retired the batter exactly as a towering pop-up did.
It did not happen often, because catchers were not standing where they stand now. With no mask and no mitt, a catcher of that period set up many feet behind the hitter and took most pitches on the hop. Moving up close was a risk reserved for moments when it was needed, such as holding a runner.
Equipment changed the geometry. The catcher's mask appeared in 1877, devised at Harvard by Fred Thayer for a player named James Tyng, and padded mitts and chest protectors followed over the next decade. Protected, catchers moved up under the bat and stayed there. From that spot a tipped ball reached them before it could drop, and a rule written for long foul flies was suddenly handing out an out for the lightest possible contact.
Players and writers of the 1880s complained that this was a cheap way to be retired. Stories of trickery circulated as well, since a sharp click at the right moment could be produced by something other than a bat, and an umpire working alone had little way to check. In 1889 the rules drew a line. A foul tip was distinguished from other foul hits, and a tip caught by the catcher standing within ten feet of the plate was no longer an out.
For a few seasons it was nothing at all, neither an out nor a strike, which rewarded hitters for barely touching the ball. In 1895 the National League made the caught tip a strike. Six years later the league extended strikes to ordinary fouls, up to two.
That sequence explains the modern rule's odd shape. The foul tip is older, as a strike, than the foul strike is. It was never folded into the two-strike limit because it had its own logic from the start: a ball that ends up in the catcher's hands is a pitch the batter failed to hit, whatever sound it made on the way.
