Checked swing

A checked swing is a type of swing in baseball. A checked swing occurs when a batter starts to swing for the ball, but stops the swing in order to allow the ball to pass without hitting it. Initially, the home plate umpire must determine if a swing was checked or not checked. An appeal can be made by the catcher or his manager, and the home plate umpire can then make a request to either the 1st or 3rd base umpire to make the call as to whether or not the swing was indeed checked. To indicate a checked swing, the umpire will make a “safe” gesture with his hands; to indicate a full swing, he will clench his fist as if to signal “out”. If a ball that passes the batter is in the strike zone, it is a strike even if a swing is checked. If a ball is hit during a checked swing, it is in play as long as it is not ruled a foul ball. The Major League Baseball rulebook doesn't contain an official definition for a checked swing; it is the decision of the umpire presiding. Generally, factors such as whether the bat passes the front of the plate or the batter pulls his wrists back are considered in the ruling. Some umpires prefer to use the "breaking of the wrists" as the method to decide a checked swing.
