Giants 10, Reds 2

CINCINNATI -- Brandon Belt and Buster Posey homered and Madison Bumgarner pitched seven solid innings, lifting the San Francisco Giants to a 10-2 victory over the Cincinnati Reds on Friday night at Great American Ball Park.

Center fielder Billy Hamilton and shortstop Zack Cozart homered for Cincinnati (18-18), which had a three-game winning streak snapped.

About the only drama came in the sixth inning when one of the Power Stacks beyond center field at Great American Ball Park, made to resemble steamboat smokestacks and used as a home-run feature, caught fire, sending thick smoke throughout the ballpark.

Two sections of stands were evacuated while firemen extinguished the flames. The game wasn't interrupted. A propane valve malfunction was cited for the blaze.

Shortly after the fire was put out, the Giants heated up again, scoring three times in the seventh off rookie right hander Michael Lorenzen.

RBI doubles from Belt and right fielder Jason Maxwell and a run-scoring single by shortstop Brandon Crawford pushed San Francisco's lead to 9-2.

Belt went 3-for-5 with a double, homer and four RBIs to pace a 13-hit attack by San Francisco, which moved back to .500 (18-18) for the seventh time this season.

After allowing Cozart's home run in the first inning, Bumgarner (4-2) mostly cruised, giving up two runs and eight hits. He allowed two homers but didn't walk a batter.

Reds starter Jason Marquis (3-2) allowed six earned runs and seven hits, including two homers, in a season-low three innings.

San Francisco didn't waste any time getting to Marquis.

Left fielder Gregor Blanco walked leading off the game and second baseman Joe Panik followed with a single. With two outs and on the first pitch from Marquis, Belt hit a towering home run into the visitor's bullpen in right field, putting the Giants ahead 3-0.

It was Belt's first home run since Sept. 25.

Cincinnati got a run back in the bottom of the first when Cozart hit his sixth homer of the season.

But Posey's two-run blast in the third, his sixth homer of the season, made the score 5-1. Third baseman Casey McGehee added an RBI single later in the inning.

That was it for Marquis, who has allowed five homers in his last 8 2/3 innings.

Bumgarner elevated an 0-2 pitch to Hamilton, who sent it into the left field seats in the fifth. Hamilton's third homer of the year made the score 6-2.

NOTES: Giants RF Hunter Pence, on the disabled list since fracturing his left forearm in the third spring training game, will rejoin the club in Cincinnati on Saturday and likely will be activated. Pence went 5-for-17 with two homers and five RBIs during five rehab appearances at Triple-A Sacramento. ... Reds 2B Brandon Phillips returned to the lineup on Friday after missing two games with turf toe. ... Giants RHP Matt Cain, on the DL with a sore right forearm, threw 30 pitches in a bullpen session on Thursday. He is expected to throw again on Tuesday and mix in breaking balls.
