CINCINNATI -- Todd Frazier hit a three-run home run and drove in four runs, and Bronson Arroyo allowed just two hits, lifting the Cincinnati Reds to an 8-1, rain-shortened victory over the San Francisco Giants on Monday night at Great American Ball Park.
The rain began to fall steadily in the fifth inning. By the sixth inning, lightning and thunder started as heavier downpours rolled in, and the game was delayed prior to the start of the seventh inning. The game was called after a 1-hour, 28-minute delay.
Frazier, Brandon Phillips, and Jay Bruce each went 2-for-3 with two runs, pacing an 11-hit revival for the Reds' struggling offense.
The eight runs matched the Reds' total for the previous four games combined.
San Francisco (39-43) has lost nine of its past 11 games. The Giants' only run came on Brandon Belt's solo homer in the fifth inning.
Arroyo (7-6) allowed one run in six innings. He walked one and struck out three while earning the Reds' first rain-shortened complete game since Cory Lidle threw five innings in a victory over Atlanta in 2004.
Giants starter Mike Kickham (0-3) has lost each of his three career starts. He pitched a perfect first inning for the third straight start, but Cincinnati got to him in the second.
Frazier's RBI single and a sacrifice fly by Zack Cozart put the Reds ahead 2-0. A two-run double by Derrick Robinson made the score 4-0. Cincinnati hadn't scored four runs in an inning since June 11.
With runners on first and second with one out in the third, Frazier launched Kickham's 2-1 pitch 441 feet into the left field bleachers. That three-run shot put the Reds ahead 7-0.
Kickham lasted only 2 2/3 innings, allowing seven runs on nine hits.
NOTES: The teams met for the first time since Game 5 of the 2012 National League Division Series. The Giants rallied from a 2-0 deficit in that series with three consecutive wins at Great American Ball Park en route to a World Series title. "Walking in here, it crossed my mind, the exciting playoff series we had here," Giants manager Bruce Bochy said. ... Robinson batted leadoff for the 11th time, something manager Dusty Baker prefers when facing a left-handed starter. ... Kickham doubled in the third for his first career hit. ... Frazier's homer was his first since June 11. ... San Francisco's Buster Posey, who earned NL Player of the Week honors after batting a big-league-best .500 last week, was back behind the plate Monday after playing first base the past two games due to tightness in his legs. .. Belt's homer was his ninth of the season, tying a career high.
