Schierholtz, Posey get big hits vs. Rockies

Torres also stars; Wellemeyer hurls four shutout frames

at Tucson, Ariz.
Friday, March 12

Giants at the plate: Andres Torres, Nate Schierholtz and Buster Posey paced the Giants' offensive outburst, collecting two hits apiece. Torres doubled twice and scored two runs, Schierholtz doubled and singled, drove in two runs and scored twice, and Posey added a double and single and two RBIs. Matt Downs tripled and scored, and Ryan Rohlinger, Roger Kieschnick, Steve Holm and Conor Gillaspie added RBIs.

Rockies at the plate: Ian Stewart had a 2-for-2 afternoon that included a hard-hit double that hit high off the wall in right-center field. Carlos Gonzalez went 1-for-3 with an RBI, and Clint Barmes went 1-for-3. Paul Lo Duca added a single.

Giants on the mound: Right-hander Todd Wellemeyer had his best outing of the spring, pitching four scoreless innings on two hits, not walking anyone, and needing only 41 pitches. Converted infielder Tony Pena gave up the Rockies' first run in one inning of work, allowing two hits while striking out two.

Rockies on the mound: Starter Jorge De La Rosa kept his strong spring going, logging four innings and giving up two runs -- one earned -- on four hits while striking out three and not walking a batter. Manuel Corpas struggled in the fifth inning, however, giving up four runs on four hits and raising his spring ERA to 10.38. Justin Speier pitched a scoreless inning of relief.

Worth noting: Jason Giambi made his spring debut for the Rockies, starting at first base and going 0-for-1. Gonzalez hit leadoff for the Rockies and stole his second base of the season. Melvin Mora started in left field for Colorado a day after starting at second base. Wellemeyer became the first Giants pitcher to go four innings in a spring game. Torres has five hits this spring and four have gone for extra bases. De La Rosa won't pitch in Sunday's game against the D-backs in Hermosillo, Mexico, but he will make the trip because it's his hometown and he plays for that city's winter league team. He will be accompanied there by special assistant to the general manager Vinny Castilla, the former big league slugger who's a legend in Mexico.

Cactus League records: Giants 8-2; Rockies 6-5

Up next: In split-squad action, the Giants face their cross-bay rivals, the Oakland A's, for the first time this spring on Saturday. Until recently, playing Oakland during the regular season or in the Cactus League virtually meant a guaranteed loss for the Giants. But that hex has ended, now that San Francisco has won seven of its last eight regular-season confrontations with the A's. Right-hander Matt Cain (1-0), who has pitched three innings in each of his two outings, will start for the Giants against Oakland left-hander Gio Gonzalez (0-1). In the Giants' other game, right-hander Kevin Pucetas (0-0) will try to stay afloat in the competition for the fifth starter's spot as he confronts the Seattle Mariners.

The Rockies travel up Interstate 10 to Phoenix on Saturday to take on the Brewers at Maryvale Baseball Park. Righty Jason Hammel will try to build on the consistent work he's turned in in his first two spring starts, in which he combined for five innings, giving up two runs while striking out three. He'll be followed on the mound by Matt Daley, Craig Baker, Andrew Johnson, Al Albuquerque, Juan Nicasio and Shane Lindsay.
