If so then why didn't you vote for him?.
Peavy had some clutch moments this year and some not so clutch moments. I think the clutch moments probably outweighed the unclutch moments. It's a tough question to ask right after his most unclutch performance, when all anybody is thinking about are his last starts against the Rockies and the D-Backs.
He did stop some skids a few time this year and he did get 19 wins and most likely the Cy Young award. Let's not forget those things.
So is he clutch? Gaslamp Ball's official answer is... maybe yes.
