On June 18, 2001 A mandate issued by the commissioner’s office imposes a two-minute limit for warm-up tosses thrown by relievers who come in during an inning, with the time starting when the pitcher enters fair territory. At the beginning of a frame, the allotted warm-up time for a hurler will be one-minute and forty-seconds, unless the game is on national television; in that event, the time limit will be increased by 20 seconds.
