The dropped third strike rule, explained

The dropped third strike rule lets a batter run to first base after strike three if the catcher does not catch the ball cleanly, but only when first base is empty or there are two outs. If first base is occupied with fewer than two outs, the batter is simply out. The rule surprises many new fans, and it works the same way in most standard rulebooks.

The rule in one paragraph

A strikeout is not always the end of the at-bat. In standard rules, if the catcher fails to catch strike three, the batter may try to reach first base. The batter becomes a runner, and the defense has to get him out the normal way: throw to first base, or tag him. If the defense does not, he is safe at first, and the pitcher is still credited with a strikeout.

That last part trips people up. The batter did strike out. He just got a chance to run because the ball got away.

When the batter may run

The rule depends on two things: whether first base is occupied and how many outs there are.

SituationCan the batter run?
First base empty, fewer than two outsYes. He may run to first.
First base empty, two outsYes.
First base occupied, fewer than two outsNo. The batter is out automatically, even if the catcher dropped the ball.
First base occupied, two outsYes. Runners are forced to move if the batter runs.

Why the restriction with first base occupied? If the batter could run in that situation, a catcher could drop the ball on purpose, pick it up, and turn an easy double play. The rule closes that loophole. With two outs, there is no double play to worry about, so the batter is free to run.

What counts as dropped

  • The ball hits the dirt before the catcher gets it. A pitch that bounces in front of the plate and is caught on the hop is not a clean catch, so the rule applies even though the catcher has the ball in his glove.
  • The ball gets past the catcher. A wild pitch or passed ball on strike three counts.
  • The catcher drops it. If the ball pops out of the glove before he has control of it, the batter may run.
  • A foul tip that is caught. A foul tip is a ball that goes sharply off the bat directly to the catcher's glove and is caught. If strike three is a caught foul tip, the batter is out.
  • A foul bunt on strike three. This is a strikeout and the batter is out, not a dropped third strike situation.

For how pitches are called balls and strikes in the first place, see the strike zone explained.

What happens on the play

  1. Strike three is thrown and the catcher does not hold it. The umpire has already called the strike.
  2. The batter breaks for first. If the rule applies, he has the right to try. The umpire may signal the play is live.
  3. The catcher finds the ball. He either throws to first or, if the batter is close, tags him with the ball.
  4. The result is an out or a safe batter. If the throw beats the runner, it is an out. If it does not, the batter reaches first.
  5. Runners may move too. Other runners can advance on the play at their own risk, just as they can on any wild pitch.

Batters should know the rule, but umpires usually remind players when it applies. If you are not sure, run first and sort it out afterward. A batter who walks back to the dugout without running is generally treated as out once the play is over.

How a dropped third strike is scored

The pitcher gets a strikeout. If the batter reaches, the scorer writes the strikeout (K) and then notes how the batter got to first, such as a wild pitch (WP) or a passed ball (PB). If the catcher throws him out, it is scored like a strikeout with an assist, commonly written K 2-3. The details of the symbols vary slightly by scorebook. How to keep score and how to read a scorebook in depth show the standard marks.

The confusion about wild pitches and passed balls is common. In general, a wild pitch is the pitcher's fault, and a passed ball is the catcher's. The scorer decides based on how hard the pitch would have been to catch.

Dropped third strikes in youth baseball

This is a rule that youth leagues change a lot. Many divisions with younger players do not use it at all, so a strikeout is always an out. Some leagues allow it but limit how many times a batter can reach, or only allow it in older divisions where catchers are better equipped to handle it. Others follow the standard rule exactly.

Because it varies, ask your coach or league which version your team plays. This is also in the baseball rules for beginners and confusing baseball rules lists as something that gets argued often.

Tips for catchers and batters

  • Catchers: Block pitches in the dirt, keep the ball in front, and know the situation before every pitch. If strike three gets away, find the ball first, then decide whether to throw or tag. See catcher basics.
  • Batters: After strike three, watch the catcher for a moment before walking away. If the ball gets by and first base is empty, run hard. A strikeout is not over until the umpire calls the batter out or the play is dead.
  • Pitchers and infielders: Be ready to back up first base. A throw that gets away from the first baseman can turn one mistake into two.
  • Coaches: Practice this play. Many teams only see it a few times a season, which is why it often goes badly.

Common mix-ups

  • "If he reaches, it is not a strikeout." It is still a strikeout for the pitcher, even if the batter is safe.
  • "The catcher must drop it for the rule to count." A pitch that bounces and is caught also counts as not clean in standard rules.
  • "A batter can always run." Not with a runner on first and fewer than two outs.
