HOUSTON — Los Angeles Dodgers outfielder Juan Pierre was placed on the 15-day disabled list today after spraining a ligament in his left knee in Sunday's 1-0 loss to the Angels.

Pierre left in the sixth inning after hurting his knee sliding into second base on a successful steal. Angels shortstop Erick Aybar fell on Pierre's knee and Pierre writhed in pain for a few moments before limping off the field.

Pierre had an MRI exam in Los Angeles today that revealed a sprained medial collateral ligament. The 30-year-old Pierre's DL stint is his first in nine seasons.

The Dodgers recalled Jason Repko from Triple-A Las Vegas to fill Pierre's roster spot. Repko joined the team in Houston today, where the Dodgers were opening a four-game series against the Astros. Repko was hitting .277 with six homers, 29 RBIs and 15 steals in 74 games with Las Vegas.

Pierre is hitting .277 with 35 steals, second in the NL. The Dodgers' regular leadoff man is baseball's active steals leader with 424.
