a pitch that the catcher should have caught but did not; allows a base runner to advance a base
a legally delivered ball that should have been held or controlled by the catcher with ordinary effort
A pitched ball missed by the catcher, allowing a runner to advance.
A pitch which the catcher cannot handle and which allows runners to advance.
A catcher's failed attempt to catch a good pitch, allowing a baserunner to advance to the next base.
A pitched ball that gets by the catcher and allows one or more runners to advance. If it occurs on a third strike, the batter may attempt to get to first base. The catcher is not charged with an error. If there are no runners on base, the catcher cannot be charged with it.
A pitch not hit by the batter that gets past the catcher, which otherwise should have been caught or stopped.
A pitch which the catcher fails to field or hold onto which allows runners to advance, and which (in the judgement of the official scorer) should have been handled with "ordinary effort". See also Wild Pitch.
A pitch that is not wild which is missed or dropped by the catcher allowing the runner to advance.
In baseball, a catcher is charged with a passed ball when he fails to hold or control a legally pitched ball which should have been held or controlled with ordinary effort, thereby permitting a runner or runners to advance or score. A runner who advances due to a passed ball is not credited with a stolen base unless he breaks before the pitch is delivered.
