Renteria departs with right ankle injury

Shortstop left after twisting it in eighth inning on Thursday

ATLANTA -- Braves shortstop Edgar Renteria left Thursday's game against Houston with an ankle injury, and had to be helped from the field.

Renteria leaned back to field a hard ground ball off the bat of Ty Wigginton. In the process, his ankle bent back and twisted. Renteria limped off the field under the aid of trainer Jeff Porter. Renteria has never been on the disabled list.

"He's going to miss some games," Braves manager Bobby Cox said. "Hopefully not two weeks -- maybe three or four games, I don't know."

With Renteria's injury and a depleted bench because of pinch-hitting appearances, Chipper Jones moved to shortstop, a position he hasn't played since he spent six games there in 2000. Willie Harris, a second baseman with the White Sox during their World Series-winning season of 2005, moved from left field to third base.

"His ankle is not good, and he hurt his back also," Cox said. "The ball kind of took him back and he rolled over his ankle."

Renteria, who went 1-for-5 in the game, is batting .336. Rookie Yunel Escobar would likely become the everyday shortstop in Renteria's absence. Escobar is currently in a platoon role at second base with Kelly Johnson. If Renteria is forced to miss extended time, Johnson would probably play full-time at second base.
