I played my home games in Coors. Granted I had a very high range team behind him (+196, -16) but this season is worth posting so here it is...
G W-L SV IP ERA OAV WHIP K/9 BB/9
25 12-7 0 153.1 2.17 .255 1.11 1.35 1.00
Game after game he continued to dominate. Until his last few starts of the season he had his ERA under 2.
Anyone else found any similar surprises lately?
