SAN FRANCISCO -- Jose Cruz Jr. and Andres Galarraga drove in three runs apiece, and rookie Jesse Foppert got his first major league victory as the San Francisco Giants beat the Cincinnati Reds 9-6 Saturday.

Galarraga and Yorvit Torrealba hit two-run homers as the Giants jumped to an eight-run lead in the fourth inning, tagging Cincinnati starter Paul Wilson (1-3) for nine hits and nine runs.

Foppert (1-2), the Giants' highly regarded 22-year-old right-hander, allowed just two hits over the first five innings before Jose Guillen's three-run homer in the sixth. He struck out six and walked six, throwing 107 pitches in just his third big league start.

But Foppert didn't need to be perfect, because the Giants' offense finally awoke following a dismal week. San Francisco (20-9), off to its best start in 30 years, won for just the second time in seven games.

After San Francisco scored just 11 runs in its previous six games, manager Felipe Alou shuffled his lineup Saturday. J.T. Snow, Marquis Grissom, Benito Santiago and Neifi Perez sat down, while Galarraga, Ruben Rivera, Torrealba and Rich Aurilia took over.

The Giants scored four runs in the first inning on Cruz's two-run triple and Galarraga's homer. They got three more in the third on Edgardo Alfonzo's RBI double and Torrealba's first homer of the season.

Barry Bonds and Cruz had back-to-back doubles in the fourth to chase Wilson, who had been the steadiest starter in Cincinnati's shaky rotation.

Kelly Stinnett had a sacrifice fly for the Reds, whose three-game winning streak ended. Over the first eight innings, Cincinnati's top four hitters -- Felipe Lopez, Adam Dunn, Sean Casey and Austin Kearns -- went 0-for-12 with seven strikeouts.

After Scott Eyre gave up four hits and two runs in the ninth, Tim Worrell got the final out for his career-best eighth save in nine chances. He retired Kearns on a flyball with two on to end it.

For the second straight day, the teams waited out more of the rain that has drenched Northern California this spring. In the Reds' 5-1 victory Friday night, there were two rain delays totaling 88 minutes.

Steady rain was falling at gametime Saturday, and crews rolled out the tarpaulin while a middle school choir sang the national anthem. The rain soon abated, and the game began 70 minutes late.

After Foppert left, right-hander Joe Nathan pitched 2 2-3 innings of scoreless relief. Nathan, who missed nearly all of the past two seasons while recovering from shoulder surgery, hasn't allowed a run in 20 1-3 innings -- San Francisco's longest scoreless streak in two seasons.

Notes: Reds manager Bob Boone vehemently argued with second base umpire Bill Miller when Aaron Boone was called out in the eighth for failing to re-touch second base when he returned to first following Guillen's flyout. Bob Boone screamed and gestured violently at Miller, but he wasn't tossed. … Aurilia returned to the Giants' lineup after missing three games with abnormally dry eyes. He went 0-for-5. … 3B Aaron Boone fumbled Galarraga's sharp grounder in the third, adding to Cincinnati's major league-worst 36 errors. But Boone made up for it with a spectacular play in the fourth, fielding Aurilia's grounder behind the bag and making a long throw. … Former Giants manager Dusty Baker, an avid fisherman, gave Alou a bunch of cooked albacore tuna when Baker's Chicago Cubs visited San Francisco earlier in the week. ''I've been eating well,'' said Alou, who's also a fisherman.
