SAN FRANCISCO -- Jose Guillen stood in front of his locker and grinned.
"I guess I'm officially a Giant now," he said. "I finally did something when it counted."
He sure did!
Guillen hit a grand slam and drove in six runs, Barry Zito won for the first time in two months and the San Francisco Giants regained first place in the NL West with a 9-2 win over the Milwaukee Brewers on Sunday.
After a loss Saturday to fall behind San Diego in the West, the Giants moved a ½-game up on the Padres, who lost to St. Louis 4-1.
"Nothing comes easy from this point on," Guillen said. "You have to be smart, go hard and do whatever it takes to win games."
Zito (9-13) pitched six solid innings to end a career-worst nine-game losing streak and record a victory for the first time since July 16. He gave up two runs and three hits, walking one and striking out three.
"The last couple of starts the team lost but personally I felt better than I have previously," Zito said. "I was building off those. After the four-spot it's up to me and not take anything for granted."
Ryan Braun hit a two-run homer for the Brewers, who were officially eliminated from the NL Central division race. Braun also robbed Cody Ross of a home run in the first inning, reaching over the fence to pull back his drive.
"It was right down the line," Braun said. "I didn't think I had a chance at it. I was pretty excited to come back with it. It was well over the fence."
Pat Burrell hit a three-run homer in the seventh and Guillen added a two-run single in the fifth.
"The main thing was finding my consistency," Guillen said. "The last few days I've been able to find it. Everything is clicking at the right time."
Guillen's first-inning grand slam off Chris Narveson (11-8) was the fifth of his career and first since June 2008.
"Braun was one of the best catches I've seen," Giants manager Bruce Bochy said. "That could have been disheartening. You appreciate the catch but I was disappointed because that was a run. That's not a great way to start a game after two tough losses and we've been having trouble scoring runs. Guillen gave us a lift right away."
Zito, meanwhile, breezed through 5 2/3 innings, retiring 16 of 18 before giving up Corey Hart's single and Braun's 23rd home run of the season.
"It seems like his arm angle was a little bit different," Braun said. "He had more movement on all his pitches and late life on everything. He's throwing the ball better than his record would indicate."
Guillen, acquired from the Kansas City Royals, has been among the Giants' hottest hitters of late. He's batting .305 since joining the Giants on Aug. 13 and is 7 for 13 over his past four games.
Posey, who was 2 for 2 with three walks, has hit safely in 11 of his last 15 games.
Narveson lost for the first time since July 28, giving up six runs and four hits over 4 2/3 innings. He walked four and struck out one. Narveson was 3-0 in his last eight decisions.
"Giving up a four-spot to them in the first inning was rough," Brewers' manager Ken Macha said. "Zito had command of his pitches."
