Catch (baseball)

Rogers Hornsby making a catch

In baseball, a catch occurs when a fielder gains secure possession of a batted ball before it bounces, and maintains possession until they voluntarily or intentionally release the ball.[1] When a catch occurs, the batter is out (said to have flied out), and runners are in jeopardy of being put out if any fielder with possession of the ball reaches their starting base before they do.

Unlike in American football and other sports, neither secure possession for a time nor for a number of steps is enough to demonstrate that a catch has occurred. A fielder may, for example, appear to catch and hold a batted ball securely, take a few more steps, collide with a wall or another player, and drop the ball. This is not a catch.

Umpires signal a catch with the out signal: a fist raised into the air, often with a hammering motion; if there is doubt about it, the umpire will likely shout "That's a catch!" On a close no-catch, the umpire will signal with the safe signal, which is both arms swept to the side and extended, accompanied by the call "No catch, no catch!" with an emphasis on the word "no".

To avoid ambiguity with the common term catch meaning any action that gains possession of a ball, some may say that a fielder gloved a thrown or batted, bouncing ball.
