Pitching is very dependent on fielding but, just eyeballing it and using "average" fielding in a neutral park as guide, I'd expect him to be somewhere around 1.35 WHIP while walking a batter every 2 innings with a K9 around 7(maybe a little better). His ERA should be around 4. You'll need to be careful with his PC. The high stamina will tempt you to use 120. I'd keep it down to 100 or 105 for max effectiveness. Because of his control, you'll need to give him a little more leash with the pull rating. He's going to walk himself into trouble. You've got to give him the chance to get out of it.
I would assume it's the same as it take to qualify for end of season league leader. 3.1 PA per game and 1 IP per game.
