SAN FRANCISCO -- When Barry Bonds' fifth-inning hit slammed into the right-field wall Saturday, it was good enough for a double and good enough for another record.

Bonds blasted career double No. 376 with the Giants on Saturday night to tie his godfather, Willie Mays, for most doubles in San Francisco history. But Bonds said tying the record is not what's important. He didn't even realize he had done it until after the game.

"I don't worry about that. You just play long enough and at the end of it, you'll see what it is."

Bonds belted another double Sunday in the fifth inning, moving ahead of Mays and giving him 2,900 career hits. It's no secret that Bonds wants to hit 3,000 before he retires, but how soon he will do it is a question to be asked of opposing teams.

"They can not throw to me if they want to. Baseball is the only sport where defense dictates the game," Bonds said.

Bonds was walked in his first two plate appearances Sunday, increasing his Major League-leading total to 84 walks this season.

Halftime hope: The Giants are halfway through the season now, and Barry Zito, who starts against Cincinnati on Tuesday, is the perfect pitcher to give the Giants a fresh start.

Zito hasn't gotten off to the season start he probably imagined, but Zito has always been a second-half pitcher. During his seven years with Oakland, Zito's second-half performance was a big part of their five trips to postseason play.

In 108 career starts after the All-Star break, Zito has gone 59-27 with a 3.26 ERA. His 59 post-break wins are the most by any pitcher since 2000, and that beats out some pretty impressive company -- Tim Hudson (57), Andy Pettitte (56) Greg Maddux (55) and Bartolo Colon (54).

"My whole career, I've always been better in the dog days," Zito said. "You get into more of a comfort zone. I can just be more myself out there like I was [Monday vs. the Padres]."

"If we get back to .500 by some point in August, then anything can happen," manager Bruce Bochy said.

Aurilia improves: Rich Aurilia made his first rehabilitation start with the Triple-A Fresno Grizzlies on Saturday, going 1-for-2 and knocking in two runs. Bochy said Aurilia will play shortstop or third Sunday and will most likely rejoin the Giants in Cincinnati on Tuesday.

Aurilia's anticipated return likely puts backup outfielders Nate Schierholtz and Fred Lewis on the bubble.

Klesko plays: First baseman Ryan Klesko was back in the lineup Sunday after he was scratched before Saturday's game with a strained abdomen. Klesko tested out the strain in batting practice before making the decision to play.

"I can't feel it doing anything but a full swing," Klesko said.

Quotables: "This is the pros; hitting is never optional," Mark Sweeney said on Saturday after seeing optional batting practice scheduled for Sunday.

On deck: The Giants hit the road for a series opener in Cincinnati on Tuesday at 4:10 p.m. PT. Zito (6-8, 4.61 ERA) will test his stuff against the Reds' Aaron Harang (8-2, 3.80).
