Padres power up to beat Giants

SAN FRANCISCO — Kevin Kouzmanoff and Eliezer Alfonzo hit three-run homers, Will Venable also homered and set a career-high with four hits, and the San Diego Padres beat the San Francisco Giants 10-4 to snap a season-high seven-game losing streak.

Kevin Correia pitched five-plus strong innings for his career-best sixth win of the season, while Luis Rodriguez drove in a pair of runs for the Padres, who broke out of a month-long slump to set a season-high for scoring.

San Diego, which had scored six runs total its previous four games, had that many in the first three innings off San Francisco starter Barry Zito. Kouzmanoff and Alfonzo both homered off the Giants’ left-hander, who was tagged with his team-leading ninth loss of the season.

The Padres, who were held without a hit by San Francisco lefty Jonathan Sanchez on Friday, broke out of their offensive slump early against Zito.

Kouzmanoff’s homer came after Everth Cabrera and Venable — son of former Giants outfielder Max Venable — led off the game with singles. Alfonzo’s three-run shot to left in the third drove in Venable and Kouzmanoff, who went a combined 8 for 10 with seven runs scored.

That was enough for Correia (6-7), who gave up three runs on eight hits in his second career start against his former team. The right-hander retired 11 of 12 during one stretch and got some help from his defense before tiring in the sixth.

He gave up a pair of one-out singles in the first but got out of the inning with a 5-4-3 double play, then held the Giants offense in check until John Bowker’s solo homer in the fifth.

Correia ran into trouble in the sixth after giving up a two-out double to Bengie Molina and walking Nate Schierholtz. Edgar Renteria and Bowker followed with RBI singles to chase Correia before reliever Luke Gregerson struck out Juan Uribe to end the inning.

San Francisco added another run in the ninth off San Diego closer Heath Bell.

Zito (5-9) had yet another rocky outing. The left-hander retired the side in order just once and was booed heavily by the crowd after surrendering the three-run homer to Alfonzo.

The booing continued when Zito left the mound after giving up three hits in the fifth. All three runners eventually scored, marking the third time in Zito’s career that he has given up nine runs or more in a game.

The loss prevented San Francisco from reaching the 50-win mark before the All-Star break for the first time since 2003.

Bowker hit his first homer of the season and his first since Sept. 24, 2008 in the fifth for the Giants, who still head into the All-Star break with the third best winning percentage in the National League behind the Los Angeles Dodgers and Philadelphia.

Venable, whose four hits are a career high, homered off San Francisco reliever Merkin Valdez in the eighth.

NOTES: Kouzmanoff had four hits for the third time in his career … Molina was back in San Francisco’s lineup after taking two days off to be with his wife for the birth of the couple’s first child, daughter Jayda Marie, who was born early Saturday afternoon. … The Giants had been a season-high 11 games over .500 before the loss.
