Aubrey Huff homered and drove in four runs as the San Francisco Giants completed the four-game sweep of the Milwaukee Brewers with a 9-3 victory on Thursday.

Andres Torres and Buster Posey each homered for the second straight game for the Giants, who outscored the Brewers 36-7 in the series.

One day after Posey’s huge game led them to a 15-2 rout, Huff and the Giants took aim against Manny Parra. Huff had an RBI single in the first, a two-run homer in the third and a sacrifice fly in the fourth that gave San Francisco a 6-0 lead.

Parra (3-6) allowed six runs - four earned - and 10 hits in five innings.

His counterpart Barry Zito was handed an early cushion, but couldn’t qualify for the win. The left-hander allowed two runs and seven hits in 4 2/3 innings. He left with the bases loaded after throwing 113 pitches.

Denny Bautista (3-0), the first of five relievers, got the final out of the fifth to earn the win. Santiago Casilla and Dan Renzler combined to work the sixth and Chris Ray threw two scoreless innings before All-Star Brian Wilson closed it out.

Prince Fielder had an RBI single for Milwaukee, which went 2-for-17 with runners in scoring position en route to its fifth straight loss.
