More to this one. Culbreth and the crew know the rules and it was argued immediately. Umpires will always get together on a rule issue and make sure that they don't lose a protest. Actually in the minors umpires are fired immediately if they lose a protest. Well, one exception-- Pam Postema blew a rule in AAA, even after the other members of her crew told her that she was wrong but she was the high profile female and kept her job.
Anyway, although the umpires would not comment post game and the league has told them not to on protests, this was an issue of the pitcher warning up becoming injured during his warm up. Ok, that's the simple answer. The rub is that umpires are told, "You are not doctors, even if a supposed injury is suspicious or seems like a convenient advantage, trust that the player is injured because they are highly paid athletes with careers on the line."
Sounds like the umpires were suckered/ forced into buying the injury excuse. I'll find out tomorrow for sure if I can.
