Dropped Third Strike Rule: When the Batter Can Run

Strike three bounces. The hitter has swung over a slider that hit the dirt a foot in front of the plate, the catcher has smothered it against his chest protector, and for a moment a strikeout is not an out. The batter drops his bat and runs. The catcher picks the ball up, steps clear and throws to first.

That scramble is Rule 5.05(a)(2) of the Official Baseball Rules, the book Major League Baseball plays under, and it fits in a sentence. A batter who strikes out becomes a runner if the catcher does not catch the third strike cleanly, provided first base is unoccupied or there are two outs. The defense has to finish the play by tagging him or by getting the ball to first base before he arrives. With first base occupied and fewer than two outs there is no play to make. The batter is out, whatever happened to the ball.

The dropped third strike rule in one sentence, and what the rulebook calls it

"Dropped" is the fan's word. The rulebook never uses it. Its phrase is a third strike "not caught," and the difference matters, because most of the pitches this rule applies to were never in the catcher's glove to be dropped. They bounced in front of him, or sailed past him, or hit the heel of the mitt and rolled away.

Three provisions do the work between them. Rule 5.05(a)(2) says the batter becomes a runner when the third strike called by the umpire is not caught, providing first base is unoccupied, or first base is occupied with two out. Rule 5.09(a)(2) says a batter is out when a third strike is legally caught by the catcher. Rule 5.09(a)(3) covers the remaining case: he is out when a third strike is not caught by the catcher and first base is occupied before two are out.

Notice the word "called." It means declared by the umpire, and it covers both kinds of third strike. A batter who watches a fastball on the corner for strike three has the same right to run as one who swung and missed, if the catcher fails to hold the pitch. It looks strange, a hitter jogging to first on a pitch he never offered at, and it is entirely legal.

1. 1The pitchWas strike three missed or taken, and not fouled? A tipped ball that reaches the ground is only a foul, and nobody runs.
2. 2The catchDid the ball reach the catcher's mitt before touching the ground, and did he hold it? If so, the batter is out.
3. 3The outsAre there two outs? If so, the batter may run no matter who is on base.
4. 4First baseWith fewer than two outs, is first base occupied? If it is, the batter is out. If it is open, he may run.
5. 5The finishThe defense must tag the batter or throw to first ahead of him. Until one of those happens he is a live runner.

The questions that settle an uncaught third strike under Rules 5.05(a)(2) and 5.09(a) of the Official Baseball Rules, in the order an umpire needs the answers.

The first step in that chart trips people up more than any other. The rule applies to pitches the batter missed or took. If the bat touched the ball and the catcher could not hold it, the pitch is a foul, and a two-strike foul changes nothing. That boundary is drawn on our page about the foul tip rule.

What counts as caught: the breaking ball in the dirt

The rulebook attaches a definition to Rule 5.09(a)(2). "Legally caught" means in the catcher's glove before the ball touches the ground. It is not a legal catch if the ball lodges in his clothing or equipment, or if it touches the umpire and the catcher grabs the rebound.

Before the ball touches the ground. Those words decide a great many plays, because the modern strikeout pitch is so often aimed at the dirt. A splitter or a slider thrown with two strikes is meant to look like a strike for fifty feet and then dive below the zone, and plenty of them hit the ground in front of the plate. A catcher who picks one of those on the short hop, cleanly, with the ball never leaving his mitt, has not caught it for the purposes of this rule. He has fielded it.

That is why catchers tag hitters who are standing still. Watch any game and it will happen within a few innings: swing and miss at a ball in the dirt, and the catcher reaches over and taps the batter on the hip or the back before tossing the ball to the third baseman. It looks like habit. It is the completion of the out. Until that tag is made, or the ball is thrown to first, the batter has not been retired.

A few variations come up often.

A pitch that hits the mitt and pops out is not caught unless the catcher secures it again before it reaches the ground. One that is pinned against the chest protector and never controlled in the hand or glove is not caught. One that glances off the plate umpire's mask and drops into the mitt is not caught, by the express wording of the definition.

And a pitch that bounces and is then swung at is a perfectly legal pitch to swing at. If the batter misses it for strike three, it is uncaught automatically, since it touched the ground on the way in.

The judgment is the plate umpire's, and it is a hard one. He is behind the catcher, the mitt is turned down and away from him, and the difference between a ball caught an inch off the dirt and one trapped against it is often invisible from where he stands. The receiving skills described in our explainer on how catchers frame pitches are judged by cameras. This one is judged by a man looking at the catcher's back.

The first-base exception: can you run with a runner on first?

With fewer than two outs, no. And the reason is a double play that the rule was amended to prevent.

Imagine the rule without its exception. Runner on first, nobody out, strike three in the mitt. The catcher opens his glove and lets the ball fall. The batter is now a runner, which means the man on first is forced to go to second, and he has not moved because he assumed the hitter was out. The catcher picks the ball up and throws to second for the force. The shortstop relays to first ahead of a batter who started late. Two outs from a pitch that should have produced one.

With the bases loaded it could be worse: step on the plate, throw to third, throw to second. Three outs, started by a deliberate fumble.

This is not a thought experiment. Catchers of the late 1860s and early 1870s tried exactly this play. Newspaper accounts from the period describe one in September 1868 who dropped strike three with the bases loaded, stepped on home plate and threw to third, and another in August 1873 who missed the third strike on purpose to start a double play that his infielders then threw away.

So Rule 5.09(a)(3) takes the option away. When first base is occupied with fewer than two outs, the batter is out on strike three whether the catcher holds it or not. No force is created, the runners may stay where they are, and the catcher has nothing to gain by dropping anything.

Readers who know the infield fly rule will recognize the pattern. In both cases the offense would be trapped by a fielder who failed on purpose, and in both the rulebook's answer is to declare the batter out at once so that the failure buys nothing. Our explainer on the infield fly rule walks through the parallel case.

Only first base matters. A runner on second, or on third, or on both, does not trigger the exception, because with first base open the batter becoming a runner forces nobody. In those situations he may run with any number of outs.

Runners and outs	May the batter run?	How the defense retires him
Bases empty, any number of outs	Yes	Tag him or throw to first
Runner on second or third only, fewer than two outs	Yes	Tag him or throw to first; other runners are not forced
Runner on first, fewer than two outs	No	He is already out
Bases loaded, fewer than two outs	No	He is already out
Runner on first, two outs	Yes	Tag him, throw to first, or force the runner at second
Bases loaded, two outs	Yes	Step on home plate, or make any other force

Dropped third strike with two outs: every runner is forced

The exception has its own exception. With two outs, the batter may run even when first base is occupied.

The logic follows directly from the purpose. The first-base exception exists to stop a cheap double play. With two outs there is no double play to steal, because the defense needs only one more out and already had it in hand if the catcher had held the ball. A catcher who drops strike three on purpose with two outs has done nothing except give the offense a chance.

So the ordinary rule comes back, and it brings forces with it. When the batter becomes a runner with first base occupied, the runner on first has to vacate it. If second is occupied too, that runner has to move, and so on around the diamond. The defense can end the inning by making a force out at any base, which is often easier than the throw to first. Our guide to the difference between a force out and a tag out covers why the fielder needs only the bag.

The neatest case is bases loaded, two outs. Every runner is forced, including the one coming home from third, so a catcher who blocks strike three and has the ball at his feet can pick it up and step on home plate. Inning over. No throw, no tag.

It goes wrong in a specific way. A catcher who is used to tagging the hitter, or throwing to first, does that by reflex with the bases loaded, and a throw to first that pulls the first baseman off the bag lets a run score that a single step would have prevented.

Runners need to know the rule as well as catchers do. With two outs and first base occupied, everyone on base should run the moment strike three hits the dirt, since each of them is forced and standing still makes the defense's job easy. A runner on third who breaks late with the bases loaded is the force out that ends the inning.

Finishing the out: the tag, the throw and the running lane

There are two ways to retire a batter who is running on an uncaught third strike. Tag him with the ball, or get the ball to first base before he touches it. He is treated in every respect like a batter who hit a ground ball to the catcher.

The tag is the easy one when the ball stays close. The hitter is still in the box or a step out of it, and the catcher reaches over.

The throw is harder than it looks. The ball is usually on the ground somewhere behind or beside the plate, the batter is running up the first-base line, and the catcher is throwing from behind the runner toward a first baseman the runner is heading straight at. Catchers are taught to clear the runner before they throw, taking a step or two into fair territory or out into foul ground to open an angle, and to tell the first baseman which side the ball is coming to. A throw made straight up the line tends to hit the batter in the back.

The lane

The batter-runner has obligations too. Rule 5.09(a)(11) requires him to run the last half of the distance to first base inside the runner's lane when a ball is being fielded to first. If he runs outside it and, in the umpire's judgment, interferes with the fielder taking the throw, he is out.

The lane changed in 2024. For generations it was a three-foot strip marked in foul territory, which forced a batter leaving the box to veer across the line into foul ground. MLB widened it that season to take in the dirt between the foul line and the edge of the infield grass, a strip the league set at between 18 and 24 inches in every park, so a batter may now run on the fair side of the chalk as long as he stays on the dirt.

Interference near the plate

The area around home is covered by its own provision. Rule 6.01(a)(1) says that if, after a third strike that is not caught, the batter-runner clearly hinders the catcher in his attempt to field the ball, the batter-runner is out, the ball is dead, and every other runner returns to the base he held at the time of the pitch.

"Clearly hinders" is a deliberately high bar. The ball often kicks off the catcher's shin guard toward the batter's feet, and the rulebook's comment says that a pitch which deflects off the catcher or the umpire and then touches the batter-runner is not interference unless he clearly hinders the catcher. A hitter who accidentally kicks a ball he never saw has usually done nothing wrong. One who stands over it, or boots it away, has. The broader distinctions are in our guide to obstruction and interference.

When the batter gives up his chance: the dirt circle

A batter who does not run has not automatically surrendered. He has to be put out, or to remove himself.

The comment attached to Rule 5.05(a)(2) sets the boundary: a batter who does not realize his situation on a third strike not caught, and who is not in the process of running to first base, shall be declared out once he leaves the dirt circle surrounding home plate. That circle, the round cutout of dirt the plate sits in, is 26 feet across on a regulation field.

The provision dates from the 2006 season. Before it, a batter could change his mind much later, and the rule let him try for first until he had reached the bench or the dugout. The winter after the 2005 American League Championship Series, in which an uncaught third strike decided a game, the rule was tightened. Whether that game was the sole cause is harder to say than the timing suggests, but the two have been linked ever since.

In practice the circle gives the defense a clock. A hitter who swings through strike three in the dirt, mutters something and walks toward his dugout is out when his foot leaves the circle, and the umpire will say so. Until then he is live. He may realize what happened and take off, and a catcher who has rolled the ball back toward the mound is in trouble.

That is why coaches drill the tag even when the hitter looks finished. The circle provision protects a defense that was slow. It does nothing for one that threw the ball away.

A batter who is heading toward first, however slowly, is "in the process of running" and is not affected by any of this. He has to be retired the ordinary way.

How it goes in the scorebook, and four strikeouts in one inning

The official scoring rules treat the strikeout and the out as separate things. Rule 9.15 credits the pitcher with a strikeout, and charges the batter with one, whenever a batter is put out by a third strike or becomes a runner because a third strike was not caught. Whether he was then retired is a second question.

What happens after strike three	Pitcher	Catcher	Also scored
Catcher holds the pitch	Strikeout	Putout	Nothing
Uncaught, catcher tags the batter	Strikeout	Putout	Nothing
Uncaught, catcher throws him out at first	Strikeout	Assist	Putout to the first baseman
Uncaught, batter reaches because the pitch was wild	Strikeout	Nothing	Wild pitch charged to the pitcher
Uncaught, batter reaches because the catcher should have held it	Strikeout	Passed ball	No error is charged
Uncaught, catcher's throw to first is wild	Strikeout	Error	Batter safe on the error

On a scorecard the out at first is written K 2-3: strikeout, catcher to first baseman. A batter who reaches is K with WP, PB or E2 beside it. The notation is covered in our guide to keeping score.

The split between a wild pitch and a passed ball is the scorer's judgment about blame, and it has consequences. A run that scores later because a batter reached on a passed ball or an error may be unearned. One that follows a wild pitch is the pitcher's own doing. The accounting is explained on our page about earned and unearned runs.

The four-strikeout inning

Because a strikeout does not have to be an out, a pitcher can record more than three in an inning. Strike out the first hitter, strike out the second and have him reach on a wild pitch, then strike out two more. Four strikeouts, three outs.

Ed Crane of the New York Giants is credited with the first, on October 4, 1888. It has been done more than a hundred times in the major leagues since, and the total creeps up most seasons, a product of pitchers throwing more two-strike breaking balls in the dirt than their predecessors did. Chuck Finley did it three times, twice for the Angels in 1999 and once for Cleveland in 2000. Through the 2025 season no major league pitcher had been credited with five in an inning.

An uncaught third strike has one other effect on the record book. A batter who reaches base on one ends a perfect game, since a man got on. It does not end a no-hitter, because no hit was recorded.

What the runners already on base may do

The ball is live from the moment it gets away. Runners may advance at their own risk, exactly as they would on any wild pitch or passed ball, and the fact that the pitch was strike three changes nothing for them.

A run can score. With a runner on third and first base open, a third strike that skips to the backstop lets the runner come home, and the batter may reach first on the same play. The strikeout still goes in the book. So does the run.

Two outs add a condition that catches people out. A run cannot score on a play in which the third out is made by the batter-runner before he touches first base. So with two outs, a runner from third who crosses the plate well before the catcher's throw reaches first has scored nothing if that throw retires the batter. The run counts only if the batter is safe. It is the same principle that wipes out a run on an inning-ending ground ball.

With fewer than two outs and first base occupied, the batter is out regardless, but the ball is still loose. Runners can move up on the wild pitch or passed ball in the ordinary way. What they cannot be is forced, because the batter never became a runner.

That last situation produces a small theater of its own. A batter who is already out will sometimes run to first anyway, either from confusion or to draw a throw. If the catcher takes the bait and fires to first, a runner on third may break for the plate. Umpires treat a retired batter running the bases as part of the game and not as interference in itself, which puts the burden on the defense to know the situation. Catchers are taught to know the outs and the occupied bases before every two-strike pitch for exactly this reason.

The umpire's signals, and what went wrong in the 2005 ALCS

A plate umpire has two different facts to communicate on an uncaught third strike, and trouble comes when one signal is taken for both. The first fact is that the pitch was a strike. The second is that the batter is not out.

The mechanic taught to amateur umpires in the United States keeps them apart. The umpire gives his strike signal without the word "out." If the ball was not caught he may add a safe signal, or point at the ground, and say "no catch." Some say nothing and simply stay with the play, watching the catcher. The point of the training is that a strike call should never look like an out call.

October 12, 2005, U.S. Cellular Field in Chicago, Game 2 of the American League Championship Series. The White Sox and the Angels were tied 1-1 with two outs and nobody on in the bottom of the ninth. Kelvim Escobar threw a low splitter, A.J. Pierzynski swung through it for strike three, and Angels catcher Josh Paul gloved the ball near the dirt, rolled it toward the mound and jogged toward his dugout.

1. 1The pitchWith two outs and the score 1-1, A.J. Pierzynski swings and misses at a low splitter from Kelvim Escobar for strike three.
2. 2The signalPlate umpire Doug Eddings extends his right arm and then closes his fist. He does not call the batter out.
3. 3The catcherJosh Paul, believing the inning is over, rolls the ball toward the mound and heads for the dugout.
4. 4The batterPierzynski starts toward his own dugout, turns and runs to first base. Eddings rules that the pitch was not caught.
5. 5The runPinch runner Pablo Ozuna steals second, and Joe Crede drives him in. Chicago wins 2-1.

The sequence of the uncaught third strike in Chicago on October 12, 2005, as recorded in accounts of the game. Replays did not settle whether the pitch touched the dirt.

Plate umpire Doug Eddings had raised his right arm and then made a fist. To the Angels that was strike three and out. Eddings explained afterward that the fist was his normal mechanic for a swinging strike and that he had never called the batter out; he had judged that the ball touched the ground and was watching to see what Paul would do. Pierzynski took a step toward his dugout, turned and ran. He was safe at first without a throw.

Pablo Ozuna ran for him and stole second. Joe Crede doubled him home. The White Sox evened the series, won the next three games and went on to win the World Series.

Replays never settled whether the ball hit the dirt, and plenty of people who watched them thought Paul caught it. There was no replay review in 2005. There would not be one for this call now either, since MLB's replay regulations confine catch-or-trap reviews to balls hit to the outfield. The judgment still belongs to the plate umpire and his crew.

The fairest reading is that two things went wrong together. The signal was ambiguous, and the catcher assumed. A tag would have cost him half a second.

Mickey Owen and Game 4 of the 1941 World Series

• 2Outs when Henrich swung
• 1Brooklyn's lead at that moment
• 4Yankees runs after the strikeout
• 7Yankees runs in the final score

New York Yankees at Brooklyn Dodgers, Ebbets Field, October 5, 1941. The four runs all scored after the strikeout that would have ended the game.

The most expensive uncaught third strike in the sport's history came 64 years before Chicago, at Ebbets Field in Brooklyn.

The Dodgers led the Yankees 4-3 in Game 4 and trailed two games to one in the Series. Reliever Hugh Casey got the first two outs of the ninth. Tommy Henrich worked the count full, and Casey threw a pitch that broke sharply down and in. Henrich swung and missed. Strike three, and for an instant the Series was tied.

The ball got past catcher Mickey Owen and rolled away toward the stands. Henrich saw it and ran. With two outs and the bases empty there was no doubt about his right to, and he reached first easily as Owen chased it. By most accounts police officers, expecting the final out, had already started onto the field to hold back the crowd.

What followed is why the play is remembered. Joe DiMaggio singled. Charlie Keller doubled off the right-field wall and both runners scored, putting New York ahead. Bill Dickey walked, and Joe Gordon doubled to bring in two more. The Yankees won 7-4, led the Series three games to one, and finished it the next afternoon.

Casey was credited with a strikeout on the pitch. Owen was charged with an error. He had been one of the surest defensive catchers in the National League that season, which is part of why the play followed him for the rest of his life.

What kind of pitch it was has been argued about ever since, with some accounts calling it a hard curve and others suspecting a spitball that Owen was not expecting. The rule does not care. The ball was not caught, first base was open, and the batter had every right to it.

Why the dropped third strike rule exists at all

It exists because it is older than the strikeout.

The Knickerbocker Base Ball Club of New York wrote its rules down in 1845, and the one on strikes reads: "Three balls being struck at and missed and the last one caught, is a hand out; if not caught is considered fair, and the striker bound to run." In that sentence the third strike is a ball in play. The batter has, in effect, hit it, and the catcher is a fielder who must catch it or throw the batter out.

The baseball historian Richard Hershberger, writing in the Baseball Research Journal in 2015, traced the idea further back, to a German book of games published by Johann Christoph Friedrich Gutsmuths in 1796. In the bat-and-ball game Gutsmuths described, a batter had three tries to hit a softly tossed ball, and after the third the ball was in play whether he had hit it or not. The purpose was to keep a hopeless batter from holding up the game without denying him the fun of running.

In the early American game the rule made sense on its own terms. Pitching was underhand and gentle, catchers stood well back, and a third strike that got away was a real fielding chance. For many years the catcher could complete the out by taking the ball on one bounce, an allowance that was removed for good in 1879.

Then catchers moved up behind the bat, gloves and masks arrived, and catching strike three became routine. The rule stopped describing a play and started describing a loophole, the deliberate drop for a double play described earlier. In 1887 the rule makers patched it by declaring the batter out when first base was occupied with fewer than two outs. The rule has had substantially its modern form since then.

Hershberger's account presents the rule as a leftover from a game that no longer exists, and that is hard to dispute. Nobody designing baseball from scratch would include it. It has survived because the 1887 patch removed the only harm it did, and because what remains is a small tax on wildness that asks the defense to finish what the pitcher started.

Where younger players do not use it

Not every level of American baseball plays the rule. It asks a catcher to block a ball in the dirt, find it and make an accurate throw past a moving runner, and it asks hitters and baserunners to know the outs and the occupied bases. Leagues for the youngest players generally decide that is too much.

Level	Uncaught third strike in use?
Major League Baseball and the minor leagues	Yes, under the Official Baseball Rules
College baseball under NCAA rules	Yes
High school baseball under NFHS rules	Yes
Little League, Major Division and older divisions	Yes
Little League, Minor League divisions	No, the batter is out on any third strike
Tee Ball	No

Little League is the clearest example. In its Tee Ball and Minor League divisions a batter is out on the third strike whether or not the catcher holds it. The full rule switches on in the Major Division, the level whose champions play in the Little League World Series in Williamsport, Pennsylvania, and stays on in the older divisions above it.

Other youth organizations and local leagues draw the line at different ages, and tournament rules sometimes differ from regular-season ones. A parent or coach should check the rulebook the league plays under and should not assume.

The first season with the rule is a rough one for most teams. Innings that would have ended on a strikeout keep going because a nine- or ten-year-old catcher could not find the ball, and hitters who struck out stand at the plate until someone screams at them to run. It earns its practice time. It is the one play in baseball where a strikeout is only the start.

High school and college baseball use the rule as the professionals do, including the first-base exception and the two-out provision. The surrounding details are not identical in every book, so the exact point at which a batter is treated as having abandoned his effort to reach first is worth checking in the NFHS or NCAA text.
