Can someone explain to me why someone who has been throwing warm up pitches needs to throw 8 more warm up pitches after a 400 foot jog (or, preferably, a 30 second bullpen cart ride)? I get it at the beginning of the inning, but these guys have just thrown at least a dozen pitches usually. If they aren't ready when you make the move, either don't bring them in or deal with the consequences. Only explanation I’ve heard is that the game mound feels different than the bullpen mound and they need some pitches to get s feel for it
