I'm not for replacing Marshall with Rain Delay in the rotation, but it's not like Sean's been blowing people away lately. Since the ASB, he has a 4.53 ERA, a 1.40 WHIP, and 23 Ks:14 BBs. In August, he had a 6.18 ERA, a 1.56 WHIP, and 13 Ks:9 BBs. Of course, the trouble is despite these very pedestrian numbers...he hasn't been appreciably less effective than either Marquis or Z. He doesn't give you the innings that either of those guys do, but that's more of a factor of his age and injury history than anything. At least presumably.
