Baseball

It must come from the player with no bench intervention. However, you can bet your bottom dollar that managers will tell players before the game starts who can and who can't challenge. The Mariners catcher, Cal Raliegh, was pretty good at it last spring. Batters are looking at the pitch from a different angle, so their challenges will naturally be successful less often, and some guys don't have much of a clue.

The couple of spring games I've seen, the players have been pretty liberally calling challenges. I don't expect that to continue when the games start counting. In the games I saw, the two challenge limit was reached pretty quickly in the early innings, leaving no recourse later in the game. Managers will be pretty strict on who can challenge and who can't.
