text: These two umpires also call checked swings, if asked by the plate umpire (often requested by catcher or defensive manager; however, only the plate umpire can authorize an appeal to the base umpire): the first base umpire for right-handed batters, and the third base umpire for left-handed batters; to indicate a checked swing, the umpire will make a "safe" gesture with his arms.
