Cardinals place Jhonny Peralta on DL with strained left thumb

The St. Louis Cardinals placed Jhonny Peralta on the 15-day disabled list Tuesday with a strained ligament in his left thumb, marking the second time this year that the veteran infielder has been sidelined by a thumb injury.

Peralta is the latest Cardinals infielder to be placed on the DL, joining All-Star third baseman Matt Carpenter (oblique) and first baseman Brandon Moss (ankle).

Despite the injuries to those three impact players, the Cardinals are not interested in trading for a hitter unless they can acquire a long-term impact player, a source told ESPN's Mark Saxon.

Peralta, 34, said he jammed his thumb while swinging the bat last weekend. Cardinals general manager John Mozeliak acknowledged that he thinks this latest injury is related to the torn thumb ligament that Peralta suffered in spring training.

"It's a different spot, but to say it's completely unrelated, I don't think anyone can tell you that," Mozeliak said.

Peralta missed the first nine weeks of the season after undergoing thumb surgery in March. He has played in 30 games since his June 7 return to the Cardinals, batting .221 with five home runs and 13 RBIs.

Moss, the Cardinals' leading home run hitter, is out of his walking boot and expected to begin a minor league rehabilitation assignment early next week, Mozeliak said. Carpenter's return is at least three weeks away.

The Cardinals announced Peralta's injury amid a series of roster moves before Tuesday's game against the San Diego Padres. St. Louis recalled outfielder Jeremy Hazelbaker and right-hander Miguel Socolovich from Triple-A Memphis and also designated catcher Michael McKenry for assignment.

Jedd Gyorko will start at third base Tuesday for the Cardinals.
