Thanks for the replies.
In reply to a couple of posts, here is the game log for the closer (Shaw) this year. Looking at his last two starts, he went 5.1 innings throwing 74 pitches and 5.2 innings throwing 97 pitches. That's a tad high for a 7 endurance rating, isn't it? At any rate, it looks like he's adapting quite well to the role as a SP, even though he can't get past the 6th inning. I'm not sure if this is a good or bad thing...
Here is the starting pitcher that he replaced in the rotation. His ratings are nowhere near as good as Shaw's, but he was #4 in the rotation in 2009 and had a decent year at 14-9 with a 4.89 ERA.
