SAN FRANCISCO - CC Sabathia’s transition from Cleveland to Milwaukee and from the American League to the National League has been seamless to say the least.

The ace left-hander pitched a complete game for the Brewers in their final game before the All-Star break and another in their first game back.

Sabathia, the reigning AL Cy Young Award winner, tossed a four-hitter Friday night to win his third straight start since joining Milwaukee, leading the Brewers past the San Francisco Giants 9-1.

“I can’t say I feel like a Cy Young winner but I feel good,” Sabathia said. “I wasn’t worried what the starts would be like. I was worried about how I’d get along with the guys in the clubhouse. That’s been the easy part. It’s been relaxing.”

It was Sabathia’s 21st career complete game and second straight. His lone blemish for much of the night was a leadoff infield single in the first inning by Fred Lewis.

Prince Fielder hit a three-run homer in the seventh to help Sabathia’s cause, then Mike Cameron added a three-run shot in the ninth.

Sabathia (3-0), pitching in his native Northern California for the first time since the Brewers acquired him in a trade with Cleveland, retired 17 straight batters until Lewis reached on an error to start the seventh. Aaron Rowand homered leading off the eighth for the second hit off Sabathia to end the shutout bid.

“He was really on tonight,” Brewers manager Ned Yost said. “He was just banging strike after strike. He was Cy Young.”

Sabathia struck out 10 and didn’t walk a batter in the 110-pitch effort.

Rowand has seen his share of Sabathia, as they faced each other in the minors.

“When he came up he threw a lot more fastballs and was more of a power pitcher,” Rowand said. “But as he’s gotten a little older, he throws a lot more of his off-speed stuff. He’s gotten better and better the longer he’s been in the league because he’s not only got great stuff but he knows how to pitch.”

He doubled in the third, his third hit in 10 at-bats this season, and scored Milwaukee’s first run. All of his hits have been for extra bases, including two home runs. He scored his team’s first run on J.J. Hardy’s RBI groundout, then Hardy doubled in a run in the seventh.

Sabathia outpitched Matt Cain (5-8) to improve to 2-4 on the road this season. Sabathia, the burly left-hander from nearby Vallejo, also won in the Giants’ waterfront ballpark in June 2005.

“He’s one of those big stoppers,” Cameron said. “He has that kind of dominating stuff.”

Giants manager Bruce Bochy was ejected for arguing a call during the fifth inning. He came out of the dugout to complain after home plate umpire Jim Wolf ruled Ryan Braun safe at third after a triple to left-center. San Francisco third baseman Jose Castillo took the relay throw from shortstop Omar Vizquel and appeared to tag Braun, but Wolf — covering third when crew chief Ed Montague ran to the outfield to watch the hit — called Braun safe.
