SAN FRANCISCO — Pablo Sandoval hit a two-run double to help Bruce Bochy earn his 1,500th win as a manager, and the San Francisco Giants split a straight doubleheader with the Cincinnati Reds with a 5-3 victory in the nightcap Tuesday.
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.
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 tipped his cap to the crowd when the milestone was announced as players shook hands afterward.
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. 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 of 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 Barry 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.
Earlier, Joey Votto and Zack Cozart also homered for the swinging Reds, who had pizza and sushi delivered to the clubhouse for a quick dinner between games.
"We've got some hot bats," Mesoraco said. "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.
