PHILADELPHIA -- On his last stride before beating out an infield single to third base Friday night, Geoff Jenkins felt a strain.
When Chris Coste erased him at second base on a double-play grounder, Jenkins said he "knew something wasn't good."
A day later, the Phillies placed their right fielder on the 15-day disabled list with a right hip flexor strain, and replaced him by purchasing the contract of first baseman Andy Tracy from Triple-A Lehigh Valley. The lefty-swinging Tracy is batting .288 with 21 home runs and 84 RBIs in 120 games for the IronPigs this season.
"I've never had this injury before, so I don't know [how long I'll be out]," Jenkins said. "It's hard, because you want to be out there with the guys."
Jayson Werth will start in right field while Jenkins recovers, though he had already been playing a lot, starting nine out of the past 14 games in right. Werth is hitting .267 with a career-high 17 home runs, while Jenkins is at .246 with nine home runs and 29 RBIs.
Jenkins suffered the strain in the third, and he appeared to be limping after beating Dodgers third baseman Casey Blake's throw to first.
Through Friday, Jenkins had played in 1,342 games without a playoff appearance, fourth-most among active players, behind the Mets' Damion Easley (1,687), the Mariners' Jose Vidro (1,419) and the Giants' Randy Winn (1,418).
Jenkins and Easley both have realistic shots of ending that spell, but Jenkins can worry about that next month. His concentration now will be to return in time to help the Phillies catch the Mets in the National League East.
"I've always been an everyday guy," Jenkins said. "I take pride in being on the field. It's tough. I want to get [to the postseason] bad. Hopefully, we can get this thing healthy."
