Disagree with the above assessments. He is equal to Hubbel against Righties and better than ANYBODY (maybe Ojeda is close) against Lefties.
If my league wasn't righty batter heavy, I would take him over Pfiester.
And better than Koufax (my favorite), McLain, or Scott in a HR park. Only Alexander, Reulbach, and Adams (no *s for the last two, and not counting Eckersley) is better.
