Again, I don't think he's really struggling. He's basically only been beat tonight by arguably the best player in baseball. That inning had a ball pop out of someone's glove, a ball hit where the defender normally would be if not for the hit and run, and another ball that would probably have been caught had Gomez been out there. But because 4 runs have scored, the average fan (not calling you that) will say Marcum sucks. Shaun Marcum's last 6 starts -- 33 IP, 46 H, 30 ER. That's an 8.18 ERA. I'm pretty sure that could be called "struggling". I'm pretty sure he said post-season. And I've said earlier, I don't think he was as bad as the numbers show in AZ. edit: And before those starts he gave up 4 runs in 34 innings. I can do it too. As many here have said, there is really no such thing as hot or cold. If a guy is a better pitcher than your other options, you usually use him.
