According to the manual, players will be injured for 25-75% of the time they are injured in real life. Under injury status, PB lists Andy Pettite with 1 injury for 101 days (games). This is simply inaccurate.

Andy Pettite was injured for approximately 32 games. I have no idea where PB got 101 days, but that would mean that he would have missed almost the entire season.

I don't know if Pettite's statistical inaccuracy is isolated, but judging from the bang up job from the commish, I really doubt it.
