Cardinals reliever Jordan Walden will be out 'a few months'

PITTSBURGH -- An MRI performed on St. Louis Cardinals reliever Jordan Walden revealed a Grade 2 strained latissimus muscle, general manager John Mozeliak said, and Walden could be out until after the All-Star break -- if he pitches for the Cardinals at all this season.

Mozeliak indicated that Walden will be out for “a few months,” in part because tests on his shoulder have also shown “significant” wear and tear on his rotator cuff.

“I do think this is one that we have to be really patient with, unfortunately,” Mozeliak said.

The Cardinals were hopeful Walden could be a key member of their bullpen this season and he fanned those hopes by pitching eight scoreless innings, with eight strikeouts, this spring. Instead, it looks as if they’ll go with Seung-Hwan Oh as their primary right-handed setup man.

“What’s disappointing is how well he was throwing. Unfortunately, he’s not someone that can go and I’m glad we added some depth,” Mozeliak said.

Also, catcher Brayan Pena is scheduled for surgery to remove floating cartilage from his left knee on Tuesday, Mozeliak said. Pena will be out 2-4 weeks, presuming the surgeon doesn’t find any other damage in his knee.
