The announcement was made a day after Schumaker returned to St. Louis to be further examined by team doctors. However, this outcome was anticipated. Schumaker expressed little optimism on Wednesday that he'd be able to avoid a second DL stint this year.
Said Schumaker: "It's about as frustrating as it can get."
Schumaker will remain in St. Louis, where he will soon begin a rehab program. Manager Mike Matheny said that Schumaker projects to miss two to four weeks as he recovers. Craig, who also had a hamstring injury, missed the minimum 15 days.
"I do know that he's a physical specimen and that he comes back pretty quick because of the extra work he puts in," Matheny said of Schumaker. "That's one you don't push real fast, real hard, but they've got an aggressive program to put him on."
Schumaker opened the season on the DL while recovering from an oblique strain he sustained during a Spring Training game. He was riding an eight-game hitting streak at the time of this latest setback.
With Schumaker out, the Cardinals will fill that center-field hole with Carlos Beltran, Shane Robinson and Adron Chambers. Beltran earned the start there on Friday.
