SAN FRANCISCO -- As the Giants rekindle their age-old rivalry for the first time in three months, the team's outfield entered a state of flux, with players shuffling in and out of the lineup and on and off the 15-day disabled list.

Before Game 2 of their set with the Los Angeles Dodgers on Tuesday at AT&T Park, San Francisco will make a 25-man roster move to accommodate Nate Schierholtz (strained left hip), who has missed 14 games. The right fielder went 4-for-18 during his five-game rehabilitation assignment at Triple-A Fresno.

The return of Schierholtz coincides with the murkier status of Aaron Rowand.

The center fielder (tight left hamstring) wasn't in Monday's starting lineup. He was available to pinch-hit (which he did with a groundout in the eighth inning) and play late-inning defense after sustaining the minor ailment while pursuing a fly ball in Sunday's loss to the Cincinnati Reds.

"He probably could play," manager Bruce Bochy said before Monday's loss. "It's not worth the risk."

While Bochy added he doesn't want his players getting "overamped" in facing their divisional foe, it will be tough for the skipper to keep Rowand on the bench for Games 2 and 3.

"It's frustrating, because you want to be in every moment you can, especially in this series," said Rowand, who would especially enjoy taking hacks against Dodgers Saturday starter Randy Wolf, against whom he's homered once in 15 career at-bats.

Another injured outfielder, Andres Torres (strained left hamstring), could return by mid-August, leaving Eugenio Velez (red hot at the plate), Fred Lewis (lukewarm) and Randy Winn (ice cold) in the mix for playing time.

Pitching matchup
SF: RHP Joe Martinez (2-0, 5.87 ERA)
Pitching in his first Giants-Dodgers game won't rattle Martinez. After enduring the skull fractures and the concussion caused by a line drive that struck him in his forehead in the season's third game, nothing should faze the 26-year-old, who won his first Major League start last Wednesday at Houston. This will be Martinez's first AT&T Park appearance since his April mishap, so expect the crowd to be solidly behind him.

LAD: LHP Randy Wolf (5-6, 3.55 ERA)
Wolf told reporters after Thursday's no-decision against the Braves that he felt he had some of his best stuff of this season on the mound that night. He also said that fact made the four runs he gave up in seven innings a little bit frustrating. Wolf kept the Dodgers within striking distance of the Braves, and his seven innings gave the bullpen an easier night. In all, Wolf pitched well and was not hit hard except for a few specific instances. Wolf is 6-4 with a 3.44 ERA in his career against the Giants.
