Preventing stolen bases by throwing to second base or third base to allow an infielder to tag a baserunner attempting to reach the base. A catcher who is very good at preventing stolen bases is said to have a low stolen-base percentage. (A pitcher who is slow to deliver is often more at fault for stolen bases than the catcher is.) Ideally, a catcher should be able to get the ball from their glove to that of the player covering second base in under two seconds. This is referred to as a catcher's "pop time", the time elapsing between the popping sound of the pitch striking the catcher's mitt and the similar pop when the ball arrives at the glove of the fielder covering second base.
