Buerhle has had three straight quality starts right now, and could have won all three with better run support. Foppert is an unproven and inconsistent rookie with a 4.58 ERA and 1.55 WHIP. Since it seems like Buerhle is turning it around, I'd start him. In a mixed league, Foppert isn't even worth having on your roster because he is too inconsistent. Unless it's a keeper league, he's waiver material.
