Cubs pitching depth

We're watching the situation with the Cubs rotation with no little amount of interest. From today's papers:

Pitcher Sergio Mitre saw his ERA balloon to 5.82 in a 7-6 loss Friday, but manager Dusty Baker said he had no choice except to keep the 23-year-old in the rotation.

"Yeah," Baker told reporters. "You got any better choices?"

Yes sir, yes. We recommend this guy.

In five innings, Mitre allowed seven runs on 10 hits, walked one batter and threw two wild pitches. He also gave up a base after he ignored a runner on a comebacker to the mound.

"This was a young man who was 7-9 in Double A," Baker said. "For his lack of experience and lack of success, he's 2-3 in the big leagues. Not many kids could come up from Double A and done what he's done. This is on-the-job training in the big leagues in the heat of a pennant race."

I can see the steam escaping from his ears as Baker contemplates the fact that he has to go with a pitcher who couldn't win in AA at the end of the pre-Memorial Day leg of the pennant race. Meanwhile our man is is winning at AAA. Something tells me the Cubs will deal for a starter or two during the July leg of the pennant race.
