Martinez didn't learn that warming up pitchers wears them out as much as having them actually appear in the game, that they prefer to come in at the beginning of the inning, or that they will say they are ready even when their arm is tired, he already knew all of that, we all know those things. His problem was not finding the right balance of accounting for those factors while still playing to win the games, so far not so good. This team needs to start winning a whole lot more games real fast and keeping the players happy better be Martinez's least concern.
