According to Evan Grant, Mendoza knew his shoulder was hurt prior to the game and even though the coaches asked him about it repeatedly, he never acknowledged the pain until he came out in the 2nd.

I think Nolan should demonstrate that we don't put up with this crap (as Jerry would say 'Stop this crap'), and not let Mendoza pitch again this year in the majors.  Probably too harsh, though, and a waste of a 40 spot.  Seriously, we've got to start playing with maturity.
