At this point in Jake Peavy's career, any type of progress on rehab assignments is notable.
Peavy tossed 5 2/3 innings for the White Sox's Triple-A affiliate Friday, giving up three runs and seven hits. He flashed his control by walking none and whiffed eight, which is a great barometer for his readiness.
"I gave up a few runs, a two-run homer late, but I made a lot of good pitches," Peavy told MLB.com. "I couldn't feel any better stuff-wise. I thought I was much better than I've been in the past. I feel better than I have in quite some time."
Peavy, who has been out with rotator cuff tendinitis, will pitch Wednesday for Double-A as the Triple-A club has an off day. The aim will be to throw 100 pitches in that outing, then evaluate his readiness for the majors. Barring any unexpected surprises (and with Peavy, nothing's unexpected), he should be able to rejoin Chicago's rotation.
That will represent an interesting issue for the 10-17 White Sox, who are scrapping to stay out of the cellar. Peavy's replacement in the rotation, Phil Humber, has pitched well, with 3.20 ERA in 35 innings. He's represented yet another success story for pitching guru Don Cooper, although it's too early to anoint Humber a legitimate pitcher. Meanwhile, Edwin Jackson has been the worst of the five pitchers with a 5.86 ERA.@cbssportsmlb on Twitter or subscribe to the RSS feed.
