I'm trying to rationalize this. Trying very hard. So here are my rose-covered glasses view point:
The perception is that Dempster just can't get outs against elite teams, so let's look at Dempsters worst four starts of the year. Those starts pretty much killed his season. But without those four starts, he had an ERA of 2.25 and never gave up more than 4 runs. That's pretty sweet, right?
[table]
Oct 3-- Oakland. 1st inning -- single, single, double, one run scores. 4th inning-- A walk, a double, and two bloop singles, by Moss, Reddick, Donaldson, Smith and Dempster is out of the game. Both inherited runners score.
Sept 18 -- LAA-- 1st inning-- a pair of bloop hits and a steal led to a run. 4th inning-- single, walk, single, walk. The score is 3-3 when they pull Dempster. Two of the three inherited runs score.
Aug 13 -- NYY-- 1st inning was perfect, 2nd inning was perfect. 3rd inning was ugly. 4th single, out, double play. 5th was perfect. 6th-- one homer, three outs. Not a good game, but there were stretches where he did dominate the Yankee lineup. It just didn't include the 3rd inning where he gave up 5.
Aug 2 -- LAA-- Another ugly game. Pujols, Trumbo and Trout took advantage of him, badly.

He had some bad games, but who knows, maybe he won't be a complete failure in Boston?
