That’s the other side of the coin. Jurrjens’ ERA went from 2.60 to 4.64, while his strikeouts and walks stayed almost exactly the same as in his two previous campaigns. So a lot of that was “luck”, balls finding holes that they didn’t before or runs getting scored “earned” instead of “unearned”. But not all of it. His homers allowed went from .6 per 9 IP to 1.0, and that was a lot of it. But still not all of it.

It’s a good idea to look at the breakdowns. Now, most pitchers are going to pitch better in wins than in losses, obviously. But Jurrjens took it to an extreme. In his seven wins, his ERA was 1.83. In six losses, it was 10.25. (In no decisions, it was 4.14.) Jurrjens oscillated between pitching as well, or better, than he ever has (his good starts included some of the best of his career) to not being able to get anyone out.

Jurrjens had a variety of injuries; a shoulder problem that popped up during offseasons workouts caused him to miss most of spring training, and he aggravated it when he tried to pitch early in the season anyway and went back on the DL. He then hurt his knee after coming back, and required surgery on a torn meniscus after the season.

Jurrjens isn’t as good as he looked in 2009 or as bad as he looked in 2010. He’s a good pitcher. He’s also about to get very expensive, and the Braves might have traded him if he’d been healthy in 2010. They might trade him this offseason, if they don’t manage to unload Lowe instead.
