SAN DIEGO -- Shortstop Edgar Renteria missed his fourth consecutive start with a strained right hamstring Tuesday, though he was available to pinch-hit in the Giants' series opener against the San Diego Padres.
Renteria remained uncertain regarding whether he'd be ready for full activity by Friday, when the Giants open their next series at Seattle.
Manager Bruce Bochy said that infielder Juan Uribe, Renteria's would-be replacement who went on bereavement leave after last Saturday's game, might be back in San Diego on Wednesday as previously announced but likely wouldn't play until Thursday. Uribe visited the Dominican Republic to spend time with an ailing grandfather.
Outfielder Andres Torres, who tested his mending left hamstring by tripling Monday while playing for Triple-A Fresno on his injury rehabilitation stint, will push himself further by playing nine innings Thursday at Iowa, Bochy said.
Right-hander Sergio Romo (elbow), who pitched a scoreless inning Monday for Fresno in his third rehab appearance, will stay in California while the Grizzlies travel to Iowa so he can stick to his throwing schedule. Romo is expected to pitch Wednesday for Class A San Jose.
In the cheeriest injury-related news for the Giants, right-hander Joe Martinez played catch for the first time since being cleared for activity. Martinez, who was skulled by Mike Cameron's ninth-inning line drive on April 9, threw at a 70-foot distance for about five minutes.
"It's still sinking," Martinez said, referring to the movement on his tosses. "I'm a little excited about playing catch, which is hilarious."
