Yankees After George Sherrill?
Presumably, Sherrill would be a backup plan if the Yanks can't acquire Mike Gonzalez. From what I hear, there are still a handful of teams involved on the Pittsburgh reliever.
Sherrill has an interesting stat line that doesn't seem repeatable - fewer than seven hits per nine, zero home runs in 40 innings, a 4.28 ERA despite six walks per nine. If used as a strict LOOGY, though, he should be pretty good.
