CINCINNATI (AP) - Miguel Cairo and Ryan Hanigan each homered twice, and the Reds hit seven in all off starter Tim Stauffer and the Padres bullpen - matching a San Diego record - while powering their way to a 13-1 victory on Saturday night.
The Reds won their fourth straight game - one shy of their season high - with their biggest home run splurge of the season.
Stauffer (7-9) gave up five homers in only three innings, tying Woody Williams' club record for most allowed in a game. Stauffer gave up three - his previous career high - in a 9-8 loss to the Mets on Monday.
Reds starter Homer Bailey (7-5) gave up six hits in seven innings, including Kyle Blanks' homer.
One of the major leagues' most homer-friendly ballparks was at its most gracious. All 14 runs scored off homers. The eight combined homers matched Great American's record for a game.
Joey Votto hit a solo homer in the first inning, latching onto a below-the-knees fastball from Stauffer. After Jay Bruce walked, Cairo hit an at-the-knees breaking pitch for a 3-0 lead.
Todd Frazier led off the second with a homer, and the Reds sent eight batters to the plate for five runs in the third. Bruce hit a two-run shot - his fourth homer in the last six games - and Hanigan completed the rally with a three-run shot that left Stauffer rattled.
The right-hander dropped the baseball that catcher Nick Hundley tossed to the mound while Hanigan rounded the bases. Second baseman Orlando Hudson then jogged to the mound for a pep talk. Stauffer retired Bailey to end the inning and his appearance - three innings, seven hits, nine runs.
It was a stunning turnaround for Stauffer, who had been at his best in his last dozen starts, putting up a 2.25 ERA.
Cairo hit another two-run shot off Anthony Bass for his first multihomer game. Hanigan had a two-run shot in the eighth off Joe Thatcher for his second career multihomer game.
It was the fourth time San Diego gave up seven in a game, the last time on Sept. 18, 2006, at Dodger Stadium. The last time Cincinnati homered seven times was July 4, 2010, at Wrigley Field.
