Mark Mulder walks two batters and leaves the game against the Phillies after recording just one out:

The Cardinals said Mulder had left shoulder discomfort and will be evaluated on Thursday.

Mulder, coming back from two shoulder operations, made his first start since September and hasn't won a game in 25 months. The former 20-game winner struck out Jimmy Rollins to start the game, then walked Shane Victorino and Chase Utley.

It seems to me the Cardinals rushed Mulder back a bit. I wonder if this means the Cardinals are more likely to trade for someone like A.J. Burnett. Burnett gave up one run through the first five innings against the Orioles tonight, but then allowed six in the sixth. That's not helping his trade value.

The Phillies break their scoreless streak with a run in the 5th, and lead the Cardinals 1-0.
