Cardinals’ manager Tony La Russa indicated Tuesday night that starting pitcher Chris Carpenter is likely to be out for a while after he strained his left rib cage during the fourth inning of St. Louis’s 9-6 loss to the Diamondbacks.

“Couldn’t throw,” Carpenter said. “I tried to throw the last one there and it hurt pretty good.”

Carpenter was removed from the game after throwing his warmup pitches for the fourth inning. The righthander was diagnosed at the scene with a strained rib-cage muscle. Carpenter later described it as an oblique injury, pointing to the left side of his torso as he explained that it was still sore after the game. He said he will return to St. Louis and meet with team doctors Thursday.
While the Cardinals wouldn’t confirm their plans to make move Wednesday morning, it is certain that Carpenter is headed to the 15-day disabled list and the Cardinals will be looking for a starter.

“The most important thing is that Chris Carpenter got hurt,” manager Tony La Russa said after his team’s 7-6 loss in extra innings to Arizona. ” No matter what happens in the game, the most important thing is it looks like he’s going to be out for awhile. That kind of overwhelms everything else that happened in the game.”

So much for Carpenter turning in a full year. The risk of him getting hurt is always high and it happened again just three starts into his 2009 campaign. Hopefully for the Cardinals’ sake, that it’s nothing too serious and that he’ll only make one trip to the DL, but either way this has to be frustrating for a team that needs Carpenter to stay healthy in order to make a serious run this season.
