Every term you'll see in a Rundown situation, explained plainly. Tap anywhere outside to close.

R1 · R2 · R3: Runner on 1st / 2nd / 3rd base.
Bases loaded: Runners on all three bases.
Tag up: On a fly ball, the runner touches the base after the catch, then tries to advance.
Leadoff: How far a runner stands off the base before the pitch. Bigger in baseball; softball requires the runner to stay on the base until the pitcher releases.

So a 6-4-3 DP = SS throws to 2B covering 2nd, 2B fires to 1B. Double play.

Cutoff: An infielder positioned between an outfielder and the target base to intercept and redirect the throw if needed.
Relay: On long throws from deep outfield, an infielder goes out to meet the throw and relays it to the base.
Backing up: A fielder positioning behind another fielder in case a throw or ball gets past.
Infield fly rule: With runners on 1st+2nd (or bases loaded) and less than 2 outs, the umpire calls the batter out on a catchable infield pop-up, so the defense can't drop it and turn a double play.
Rundown (pickle): A runner caught between bases. Defense runs the runner back to the previous base with the fewest throws possible.

RHB · LHB: Right-handed batter / Left-handed batter. Affects which middle infielder covers 2nd on a steal.
Sacrifice bunt: Batter bunts expecting to get thrown out so the runner can advance.
Squeeze: Runner on 3rd breaks for home while the batter bunts. Suicide squeeze = the runner is already going.
Steal: Runner advances on the pitch without the ball being hit.
Double steal: Two runners advance at the same time.

Slapper: Left-handed hitter who starts moving toward 1st while swinging. Slap contact creates tough infield plays.
Leaving early: A softball runner cannot leave the base until the pitcher releases the ball. Leaving early = out.

Pickoff: Pitcher throws to a base to catch a runner who's leading off too far.
Dropped 3rd strike: If catcher doesn't cleanly catch strike 3, batter can try to reach 1st, when 1st base is open or with 2 outs.
Balk: Illegal pitcher motion that advances every runner one base.

Infield in: Fielders play shallower to try to cut down a run from 3rd base. Gives up range for speed home.
Infield back: Normal depth. Prioritizes the out, concedes the run from 3rd if needed.
Hold the runner: 1B stands on the bag to prevent a big lead.
