The Dropped Third Strike Rule: When a Strikeout Is Not an Out
A third strike does not always end the at-bat. This guide explains when a batter may run after a dropped third strike, why first base and the number of outs matter, how the play is scored, and where the rule has decided games.
A batter who swings and misses at strike three has struck out, and the strikeout counts in his statistics and against the pitcher's line. But he is not necessarily out. If the catcher does not hold the ball cleanly, and the situation meets two simple conditions, the batter may run to first base, and if he gets there safely he is a baserunner who has also been charged with a strikeout.
The rule is short, rarely invoked and regularly misunderstood by fans, young players and even some coaches. This article sets out exactly when it applies and when it does not, gives a table of situations you can check against, explains the reasoning behind the two conditions, shows how the play is scored, and looks at two famous October moments in which it mattered. Rule numbers below follow the current Official Baseball Rules; for the full text, check the rulebook published by Major League Baseball, since rules are revised from time to time.
The rule in plain language
The core of the rule is in two parts of the Official Baseball Rules. The batter is out on strike three when the catcher legally catches the ball (Rule 5.09(a)(2)). He also becomes out automatically on strike three, even if the ball is not caught, when first base is occupied before two are out (Rule 5.09(a)(3)). In every other situation, an uncaught third strike turns the batter into a runner (Rule 5.05(a)(2)).
Put as a checklist, the batter may run after strike three only if both of these are true:
- The catcher did not legally catch the pitch.
- Either first base is empty, or there are two outs.
If the catcher catches the ball, the batter is out. If the catcher drops it but there is a runner on first base and fewer than two outs, the batter is out anyway. If the catcher drops it and first base is empty, or if there are two outs with any runners on, the batter may run, and the defense has to get him out.
A table of every situation
The rule only depends on three things: whether the catcher caught the ball, whether first base is occupied, and how many outs there are. That makes it possible to list every case.
| Catcher catches the pitch? | First base | Outs | Batter |
|---|---|---|---|
| Yes | Any | Any | Out |
| No | Empty | 0, 1 or 2 | May run; must be put out |
| No | Occupied | 0 or 1 | Out immediately |
| No | Occupied | 2 | May run; must be put out |
The second and fourth rows are the ones that surprise people. In the second, a runner is not on first base, so the catcher's mistake gives the batter a chance. In the fourth, the batter can run even though first base is occupied, because with two outs the defense can end the inning by getting any runner or the batter out. The rule is called the dropped third strike rule, but a pitch that gets by the catcher, bounces off his chest protector or is blocked and rolls away is treated exactly the same as one he drops.
Why first base and the outs matter
The restriction in row three, that a batter is out automatically with a man on first and fewer than two out, exists to stop a trick. Suppose the batter were allowed to run in that situation. A catcher with a runner on first could deliberately let the ball drop, pick it up, throw to second base for a force out on the runner, and then watch the second baseman relay to first to retire the batter. The defense would turn a strikeout, which should be one out, into a double play on a single pitch.
Baseball's rulebook closes that loophole by declaring the batter out whenever there is a runner on first base and fewer than two outs. The batter can no longer be used as a decoy to force a runner, and a catcher gains nothing by dropping the ball on purpose. It is the same kind of reasoning that produced the infield fly rule, which protects baserunners from a defense that could otherwise drop a pop-up on purpose to get two outs. In both cases the sport protects the offense from a play that would be unfair but technically possible.
With two outs the trick no longer works. A force at second base would be the third out, ending the inning, so there is no double play to be had and no reason to bar the batter. That is why the rule applies with two outs even when first base is occupied. It is also why a batter with two outs and runners on, who may be able to extend the inning by running, should always run on a dropped third strike.
What counts as a legal catch
Everything depends on the catcher having caught the pitch, and the rule defines that carefully. A catch must be made before the ball touches the ground. If the pitch hits the dirt first and the catcher scoops it up, the ball has not been caught, even if the catcher is holding it when the umpire looks. This is the heart of many arguments, because the catcher's glove and the dirt are often only inches apart and the pitch is moving fast. The home-plate umpire makes the judgment, and it is a judgment call.
A catch also requires the catcher to hold the ball. If he catches it cleanly and then drops it while taking it out of his glove to throw, the umpire's judgment is that he caught it and the batter is out. If the ball hits his glove and bounces away, it was never caught, and the batter may run.
Two related situations need separating. A foul tip, a pitch the batter barely touches that goes directly to the catcher's glove, is a strike. If the catcher holds a foul tip on strike two, the count is two strikes; if he holds it on strike three, the batter is out. If he does not hold it, it is a foul ball and the batter stays at the plate. A bunt attempt that goes foul with two strikes is a strikeout, an out, with no running allowed.
What the batter can do, and when he is out
The batter on a dropped third strike has become an ordinary runner, though he does not have to be forced to run. The catcher can retire him in either of two ways: by tagging him with the ball or his glove with the ball in it, or by throwing the ball to first base so that it arrives before the batter touches the bag. A throw that beats him is a putout for the first baseman and an assist for the catcher.
The rule has one oddity about not running. If the batter does not realize the ball was not caught and leaves the dirt circle that surrounds home plate, he is declared out. A batter who stands in the box and does nothing while the catcher picks up the ball is not yet out, since he could still run, but one who heads toward the dugout and steps outside the circle has given up his chance. At every level, coaches tell hitters the same thing: do not leave the plate until the umpire calls you out, and if the ball gets away from the catcher, run.
The batter may run even when the defense has plenty of time to throw, for the same reason that any runner may run out a ground ball: the defense can still make a mistake. A hard throw from the catcher's knees, a first baseman who stretches too early, or a tag attempt that misses can all turn a routine out into a safe runner.
Runners already on base
A dropped third strike is a live ball. The runners already on base may advance at their own risk, in the same way as on a wild pitch, and the defense may try to get them out. When first base is occupied with two outs, a runner who advances can score on a pitch that also lets the batter reach first.
When first base is occupied with fewer than two outs, the batter is out immediately, but the ball is still live for the runners. A runner on second who sees the ball roll to the backstop may try for third. The result is a strikeout that also becomes a wild pitch or passed ball with a runner advancing, a combination that can score a run without a hit.
The situation puts a premium on the catcher's skill: blocking a ball in the dirt keeps it in front of him, so that runners are held and the strikeout is not turned into a baserunning advantage. Catchers practice blocking for precisely this reason.
How the play is scored
The scoring of a dropped third strike has a few details worth knowing, which is why the play is a favorite in scorekeeping classes. The batter is still charged with a strikeout (K) and the pitcher is credited with it, whether or not the batter reaches. If the catcher throws him out at first base, it is scored as a strikeout with the putout going to the first baseman (K 2-3 in standard notation), where the 2 stands for the catcher and the 3 for the first baseman.
If the batter reaches first base because the pitch got past the catcher, the official scorer charges either a wild pitch to the pitcher or a passed ball to the catcher, depending on whether the pitch was catchable with ordinary effort. If the batter reaches because the catcher made a bad throw, an error is charged to the catcher. In all of these cases the strikeout still counts.
| What happened | Strikeout charged to batter and pitcher? | Other entry |
|---|---|---|
| Catcher throws batter out at first | Yes | Putout, first baseman; assist, catcher |
| Catcher tags batter | Yes | Putout, catcher |
| Pitch gets away; batter reaches | Yes | Wild pitch or passed ball |
| Catcher's throw is wild; batter reaches | Yes | Error, catcher |
| First base occupied, fewer than two outs | Yes | Putout, catcher |
You can practice with the site's scoresheet tool, which is useful for learning how these entries look in a game record. A passed ball and a wild pitch are the key distinction: a pitcher who throws a ball no catcher could handle is charged, and a pitcher whose pitch is a reasonable one to catch is not. The decision rests with the official scorer.
Why batters reach on strikeouts: the knuckleball and the dirt
In practice the rule matters most on pitches that are hard to catch. A knuckleball, which has little spin and moves unpredictably, is the classic example: catchers have to adjust their equipment and technique, and a knuckleballer's catcher has a harder time than most holding on to the ball. Breaking balls in the dirt are the other typical cause, especially with two strikes, when a pitcher throws a pitch intended to be swung at and missed.
That is why a two-strike slider that bounces is a more dangerous pitch than it looks. The batter swings and misses, the catcher blocks it but the ball squirts away, and the batter who would have been out ends up at first base. A pitcher who strikes out ten batters in a game and watches two of them reach first base has still struck out ten, and the strikeout totals in the box score do not tell you which ones were caught. It is one of the many things a box score cannot show; how to read a baseball box score lists the details it does carry.
Two famous cases
The most famous dropped third strike in baseball history came in the 1941 World Series. In Game 4, with the Brooklyn Dodgers ahead and two outs in the ninth inning, the Yankees' Tommy Henrich swung and missed a third strike. Brooklyn catcher Mickey Owen did not hold the pitch, and Henrich reached first base. The Yankees went on to win the game and, in the historical record's record of the Series, won it four games to one. For decades afterward, the play was one of baseball's best-known mistakes.
The second case came in the 2005 American League Championship Series. In a tied game in the ninth inning, with two outs, Chicago White Sox batter A. J. Pierzynski swung and missed at a low pitch. The Angels' catcher, Josh Paul, believed he had caught it and rolled the ball toward the mound; umpire Doug Eddings ruled that the ball had hit the ground, so the batter was entitled to run, and Pierzynski ran to first base. The White Sox scored in the same inning to win the game. The arguments afterward were about the umpire's judgment on whether the ball had been caught, which is exactly the kind of judgment call the rule leaves in his hands. Both plays are reminders that the rule can change an inning, a game and, in October, a series. For more on how the postseason is structured, see how the MLB postseason works.
The batter's and catcher's playbook
For hitters, the practical advice is simple. On any strike three that is not clearly caught, run, unless first base is occupied with fewer than two outs. Do not rely on the umpire to tell you; the umpire will signal a catch, or "no catch", but if you are watching the catcher's glove you may be a step late.
For catchers, the advice is to block rather than catch, whenever the pitch is in the dirt, and to make sure the umpire sees the catch when the pitch is caught cleanly. Some catchers make a point of showing the ball to the umpire or tagging the batter, a habit that removes the argument. For pitchers, the two-strike dirt ball is both a weapon and a risk, and the rule is part of why they trust their catchers to block.
For coaches, the lesson is bookkeeping: with a runner on first base and fewer than two outs, the batter must not run on a dropped third strike, but the other runners may still try to advance on the live ball. Players at any level should learn the table above.
The rule is the same in the major leagues, in college and in high school, and in the softball codes. Youth leagues sometimes modify it for younger age groups, either turning the rule off because young catchers drop many pitches or restricting it to certain divisions. The reason is practical, since a rule that turns most strikeouts into baserunners makes games long and defenses frustrated. If you coach or play in a youth league, consult that league's rulebook; for guidance and local rules, see the pages on youth baseball and the topic page for rules and umpiring.
Rules that govern the pace and structure of play have changed in recent seasons, from the pitch clock to restrictions on defensive shifts, and some readers wonder whether the dropped third strike might be next. The rule has been part of the game, in some form, since the nineteenth century, and as of the 2025 season it remains in the Official Baseball Rules. For the recent changes, see the pitch clock in detail and the shift restrictions explained.
Common questions
Can the batter run if the catcher drops strike three with a man on first and one out? No. With first base occupied and fewer than two outs, the batter is out automatically, whether or not the catcher holds the ball.
Can he run with two outs and a man on first? Yes. With two outs, a dropped third strike lets the batter run regardless of who is on base, because a force out ends the inning.
Does the pitcher still get a strikeout? Yes. The strikeout is credited to the pitcher and charged to the batter whether or not the batter reaches base.
What if the batter does not run? If he leaves the dirt circle around the plate, he is out. If he stays in the batter's box, he is not yet out, but the catcher can tag him or throw to first.
Is it a wild pitch or a passed ball? The official scorer decides. If the pitch was one an ordinary catcher should handle, it is a passed ball; if it was beyond reasonable reach, it is a wild pitch.
