--SS Edgar Renteria's homer gave the Giants their first first-inning run since opening day. It was Renteria's second homer of the season. He was hitting second in the lineup, having flip-flopped with 2B Emmanuel Burriss, something manager Bruce Bochy said he'd do when the Giants face a lefty. Arizona started LHP Doug Davis.

--RHP Sergio Romo (elbow) is with the team in Arizona, only to resume his rehab. He has been working out in extended spring training, and manager Bruce Bochy said he could throw a bullpen session before Sunday's game. Romo said it'll be at least mid-May before he'll be strong enough to pitch in a game.

--3B Pablo Sandoval has hit safely in six of seven games, hitting .345 (10-for-29). The stretch corresponds with his drop in the lineup to sixth. Previously, he was in the Nos. 3 and 5 slots, and manager Bruce Bochy said hitting sixth could take some pressure off. So far, he has been right.

MEDICAL WATCH:

RHP Joe Martinez (concussion, hairline fractures in skull) went on the 15-day disabled list April 10. He is unlikely to return before late May.

LHP Noah Lowry (left forearm surgery in March 2008, left elbow surgery in September 2008) went on the 15-day disabled list retroactive to March 27. In mid-April, manager Bruce Bochy said he hoped Lowry would able to return at some point this season.

RHP Sergio Romo (sprained right elbow) went on the 15-day disabled list retroactive to March 27. He could return as soon as early May.
