In Friday's contest, Huff went 3-for-5 with two home runs, and he followed that with another 3-for-5 performance Saturday. Huff drove in two runs for the Giants, who have won the first three in this four-game set.
Madison Bumgarner (4-2) took the win after limiting Arizona to two runs on five hits and three walks in seven innings. He also struck out seven as he won his fourth consecutive start.
While the Giants won, outfielder Eugenio Velez was injured in the fourth inning while in the dugout, as he was struck in the head by a foul ball off Pat Burrell's bat. Velez fell to the ground and, after being attended to by trainers, was carried off on a stretcher and taken to a hospital, where he will remain overnight.
Ian Kennedy (5-8) gave up four runs in 6 2/3 innings to take the loss for Arizona, which has lost six in a row to the Giants.
The majority of the scoring was done in the late innings. Huff's run-scoring groundout in the first got the Giants on the board, and in the fifth, they added runs on Edgar Renteria's groundout and Buster Posey's single.
Mark Reynolds' solo homer in the sixth made it a 3-1 game.
But the Giants opened a big lead in the seventh thanks to Uribe's blast. With two outs, Kennedy walked Renteria before being removed. Jordan Norberto entered and gave up a single to Huff, the only batter he faced. Sam Demel came in from the bullpen and walked Posey to load the bases for Uribe. Demel threw a first-pitch fastball down in the zone, but Uribe put a good swing on it and lifted it out to left field, giving San Francisco a 7-1 lead.
After Tony Abreu plated a run with a sacrifice fly in the home seventh, the Giants tacked on three more in the eighth on Andres Torres' RBI single, Renteria's run-scoring groundout and Huff's RBI base hit.
Adam LaRoche hit a two-run homer in the eighth inning to complete the scoring.
