SAN FRANCISCO -- Left-hander Tony Cingrani held the San Francisco Giants to two runs in 6 2/3 innings and recorded his first career RBI as the Cincinnati Reds rolled to a 9-3 victory Tuesday in the first game of a doubleheader.
Cincinnati was scheduled to send Greg Reynolds, making his Reds debut, to the mound in the nightcap against San Francisco's Barry Zito. Game 2 was the makeup of a July 4 rainout in Cincinnati.
On the heels of an 11-0 thumping of the Giants in the series opener Monday, the Reds jumped all over San Francisco left-hander Eric Surkamp (0-1) for four runs in the second inning and three more in the third en route to the comfortable win.
Entering the doubleheader nightcap, the Reds held a 5-0 record against the defending World Series champs this season, having outscored them 34-6.
Shortstop Zack Cozart drove in two runs with four hits, including a solo home run in the fifth inning, and catcher Devin Mesoraco homered for the second day in a row, a three-run blast in the second. Mesoraco had three of the Reds' 15 hits.
Joey Votto also homered for the Reds, his 16th of the season, a solo shot that led off the third. Third baseman Todd Frazier added two hits and two RBIs.
Cingrani (4-1) gave up a first-inning run on a Pablo Sandoval sacrifice fly, then only four more hits and one more run until departing after throwing a season-high 118 pitches. It was his fifth consecutive start allowing two runs or fewer.
Guillermo Quiroz drove in the second Giants run off Cingrani with a fourth-inning sacrifice fly.
Right-hander Alfredo Simon pitched the final 2 1/3 innings for the Reds, giving up a ninth-inning run on a fielder's choice groundball by Kensuke Tanaka. Quiroz scored the run after belting a one-out double.
Surkamp was making his first major league start since undergoing Tommy John surgery on his left (pitching) elbow last July. He failed to complete the third inning, pulled after Cingrani's two-out RBI blooper over the head of shortstop Brandon Crawford.
Surkamp gave up seven runs on nine hits in 2 2/3 innings.
Both starting pitchers were promoted from Triple-A before the game as a 26th man on the roster, allowable for doubleheaders. Cingrani was demoted in between games so that the Reds could use the same allowance to call up Reynolds from Triple-A Louisville and start him in Game 2.
NOTES: The Reds reached the 100-game mark with a 57-43 record, three games worse than last year's 60-40 mark. ... Before Game 1, the Giants sent RHP George Kontos to Triple-A Fresno after he threw a career-high 63 pitches in relief of RHP Tim Lincecum in Monday's game. RHP Yusmeiro Petit was summoned from Fresno to take his place and saw immediate action, replacing Surkamp in the third inning and providing 5 1/3 innings of two-run relief. ... San Francisco designated RHP Hunter Strickland, who had been pitching for Class A San Jose, for assignment to create a spot on the 40-man roster for Petit. ... Former San Francisco closer Brian Wilson is scheduled to throw for major league teams Thursday in Los Angeles after having held a private session for the Giants on Monday in San Francisco. Wilson hasn't pitched in game action since April 12, 2012, when he injured his right (pitching) elbow and subsequently underwent a second Tommy John surgery.
