Which position player and which pitcher is the best out of these players?

Juston Upton and Randy Wolf. Upton is having a good year but one that he can maintain. Some of the guys you have listed will have trouble keeping their stats up. They are playing over their heads. Wolf has 44 SO's in 48 innings. Coupled with a 2.77 ERA and a 1.07 WHIP, he is awesome this year. Last week he had 8 SO's in 6 innings. With a 1.50 ERA and 1.00 WHIP. Wandy is good, Wolf is better.
