Crap - Sproat has arm talent, but cannot be in the zone enough for MLB hitters to respect it and when he is in the zone they can hit it hard as we saw earlier this year.
Sproat and Harrison were supposed to help solidify the starting staff, but they are the two biggest wild card, well Harrison is, Sproat should not be on the team in October, and will hopefully start next year in AAA and see if he can locate better. Bummer that Peralta trade looks even worse with a lost season for Jett as well.
