It was clear that something was wrong with Roy Oswalt.

The Phillies righthander has struggled the entire season with a variety of issues, including a back injury, a loss of velocity and an inability to locate his pitches. Thanks to those problems, he went into his start Thursday in St. Louis with a 1-3 record and 4.81 ERA in June.

Things got worse on this night for Oswalt as he departed after just two innings because of more back pain. He allowed four runs on five hits and appeared to be in some discomfort as the Cardinals scored three runs on four hits in the bottom of the second inning.

The Phillies announced that Oswalt left with lower back tightness and that's a bad sign for a man who has had back problems in recent years.

We'll update after the game.
