SAN FRANCISCO -- It took a few more tries than Bruce Bochy would have liked to earn his 1,500th managerial win.
He might remember this one for a while considering it came in the nightcap of a doubleheader wearing road gray uniforms while batting first as the home team.
Pablo Sandoval hit a two-run double to help Bochy reach the milestone victory, and the San Francisco Giants split a straight doubleheader with the Cincinnati Reds with a 5-3 victory in the nightcap Tuesday.
"I don't know what that number means, except I'm fortunate I've been doing this as long as I have," Bochy said. "I'm thankful. I know how lucky I am."
Hunter Pence hit an RBI single, Gregor Blanco had a sacrifice fly and Brandon Belt added an RBI groundout in San Francisco's first win in six tries against the Reds this season after being outscored 34-6 in the first five meetings -- including 11-0 on Monday night and 9-3 in the opener Tuesday. The Reds had 10 hits after combining for 32 in the first two games of this series.
The teams were forced to make up a July 4 rainout at Great American Ball Park. Cincinnati batted last and wore home uniforms as the visiting team.
Bochy became the 21st manager with 1,500 wins and third active along with Reds skipper Dusty Baker and Detroit's Jim Leyland. Bochy said "it's very humbling" to be mentioned among such managers.
"He's a fine manager. He's a guy that I enjoy managing against," Baker said. "I didn't even know it was 1,500, so congratulations to Bruce."
Bochy tipped his cap to the crowd when the milestone was announced as players shook hands afterward. And Barry Zito, the pitcher Bochy removed one out from qualifying for a win, praised the skipper's feat.
"I think he's a very underrated manager, maybe because he's a quiet guy and doesn't toot his own horn," Zito said. "That's a very special accomplishment, and we're all very happy for him."
The Giants were outscored 34-6 over their first five games with Cincinnati before doing just enough in Tuesday's second game.
Devin Mesoraco had a three-run homer among his three hits in the opener to put him at 6-for-9 with two homers through the first two games of this series. He didn't start the second game but struck out as a pinch hitter to end the seventh, with a runner on second, and stayed in the game.
The Reds called up former Stanford right-hander Greg Reynolds (0-1), a native of nearby Pacifica, from Triple-A Louisville to start the second game. He allowed five runs and eight hits in five innings in his first big league outing since a start Sept. 25, 2011, for Colorado.
Santiago Casilla (4-2) struck out two in 1 1/3 innings for the win, then Sergio Romo recorded the final four outs for his 24th save in 27 opportunities. He struck out Brandon Phillips to end the eighth with two runners aboard, then struck out the side in the ninth after Jay Bruce's leadoff single -- including Mesoraco to end it.
Casilla was the third pitcher in relief of struggling lefty Zito, replaced after allowing a pair of two-out hits in the fifth, including Todd Frazier's RBI double.
Zito, who won Game 1 of the World Series last fall, saw his winless streak reach nine starts since the lefty beat Oakland on May 30.
Frazier finished with two doubles and three of Cincinnati's hits on a night the Reds missed multiple chances. They stranded 14 baserunners, seven in scoring position. Bruce also had three hits.
"We were never really out of it," Bruce said. "We just couldn't get the timely hit, and Barry was making enough pitches to skirt around it."
"We've got some hot bats," Mesoraco said after the opener. "Ride it out as long as you can. You want to go out there and put up as many runs as you can, especially early, and take a little pressure off the starting pitcher. That's what we were able to do the last two nights."
Cozart finished 4-for-4 with two RBIs and three runs to back Tony Cingrani (4-1). The left-hander was added to the roster as the Reds' permitted 26th player for the doubleheader. He was headed back to the Arizona Rookie League after the game to fulfill the final five days required after being optioned previously to the minors. He is set to return and start Sunday for Cincinnati.
The Reds had dominated the Giants this year after allowing San Francisco to rally from an 0-2 deficit to win the NL Division Series matchup last October.
In the opener, the Reds knocked Eric Surkamp (0-1) out after 2 2/3 innings in his first start since late September 2011 after undergoing Tommy John elbow surgery.
"I still have a lot of work to do coming back," Surkamp said. "I feel like I'm close. I feel a little herky-jerky throwing pitches."
