"Manager Challenges" -- Louis Sheehan's notes

Manager Challenges

1. Each Club will receive: (a) two (2) Manager Challenges to start each All- Star Game, postseason game and Divisional or Wild Card tie-breaker game; and (b) one (1) Manager Challenge to start every other game. A Manager may challenge as many reviewable calls within a single play as he desires using one challenge. If the Replay Official overturns any call challenged by a Club (even if he upholds other challenged calls), the Club retains its Manager Challenge. If the Replay Official does not overturn any of the calls challenged by a Club, the Club will lose its Manager Challenge. Once a Club has exhausted its available Manager Challenge(s), it will no longer have the ability to challenge any additional play or call in the game.
2. A Club's Manager is the only person authorized and permitted to request or initiate Replay Review on behalf of the Club during a game, unless the Manager cannot perform his Replay Review responsibilities due to injury, illness, ejection, removal or other legitimate reasons, in which case the coach designated to assume the Manager's responsibilities shall have the sole right to request or initiate Replay Review. As used in these Regulations, the term "Manager" refers to a Club's Field Manager or such other person who assumes his duties as described above.
3. Upon being prompted by the Umpire, a Manager must immediately inform the Umpire whether he wishes to use his Manager Challenge to invoke Replay Review. If, upon such prompting, the Manager does not immediately respond that he is using his Manager Challenge, then the Umpire shall revoke the Manager's right to challenge any call relating to that play, and the Club shall retain its Manager Challenge.
