Bourjos leaves game with strained hamstring

ANAHEIM -- Angels center fielder Peter Bourjos left Thursday's game against Seattle after straining his right hamstring.

Alberto Callaspo came in immediately to run for Bourjos after he suffered the injury rounding second on his eighth-inning double. Manager Mike Scioscia said that the measure was precautionary, as Bourjos experienced tightness in his hamstring. With three games remaining before the All-Star break, Los Angeles may play things safe.

"He might have limited availability," Scioscia said. "But to play center field, obviously you need to run, so we're going to see how this thing sets up. We don't want this thing progressing. Right now it looks like its manageable. So we'll see how it sets up over the weekend, and obviously we'll use the [All-Star] break."

Bourjos is hitting .272 this season, including a .412 mark on the Angels' current 10-game homestand. Bourjos' true value has come in the form of his defense, though, with many singing his praises as an early Gold Glove candidate in center field.
