Cards place Penny on 15-day DL

ST. LOUIS -- The Cardinals placed Brad Penny on the disabled list on Saturday, due to a strained right lat muscle, but general manager John Mozeliak expressed optimism that Penny will be out for only the minimum 15 days. St. Louis recalled right-handed pitcher P.J. Walters from Triple-A Memphis to take Penny's roster spot.

Penny received an anti-inflammatory shot in the area of the injury on Saturday morning. The club hopes he can resume throwing in approximately 7-10 days, and be back on the mound in a game in 15 days.

"Right now, we think it'll be a minimal stay on the 15-day [DL]," Mozeliak said on Saturday morning. "That's what we're hopeful of."

Penny said he first felt the injury after he pitched last weekend in Cincinnati, and that he aggravated it while pitching on Friday night against the Angels.
