Renteria’s grand slam powers Giants past Padres

SAN FRANCISCO — Edgar Renteria hit a grand slam off Jake Peavy and matched his career high with five RBIs, leading the San Francisco Giants to an 8-3 victory over the San Diego Padres on Tuesday night.

Renteria connected in the fourth for his first homer with the Giants, who have won three of four. It was his seventh career grand slam and the first allowed by Peavy in his seven-year career.

Peavy, who struck out 10 and came within two outs of a complete game in a 6-3 win over the Giants on April 11, allowed six runs and seven hits in six innings.

Matt Cain beat San Diego for the first time since 2006 and improved to 2-0 for the first time in his career. The right-hander, who didn’t get his first win last year until April 23, scattered nine hits over six innings, yielding just two runs.

Renteria was batting just .200 through the first two weeks, leading to some early criticism for the shortstop’s $18.5 million, two-year deal with the Giants in the offseason.

But Renteria added to his history of success with Peavy, collecting three more hits off the San Diego ace to raise his career average to .455 against right-hander.

He scored the Giants’ first run on a double-play grounder in the third then hit the first pitch he saw from Peavy in the fourth deep into the left-field stands to make it 5-2. The home run was just the sixth of the season for the Giants, lowest in the NL and second-fewest in the majors behind Oakland.

Peavy (2-2), the 2007 NL Cy Young Award winner, took a step backward after two solid starts and couldn’t recover after Renteria’s grand slam.

It was the first grand slam allowed by Peavy in 1,284 1-3 innings, the second-longest active streak in the majors, according to Elias Sports Bureau. Houston Astros right-hander Brian Moehler has the longest active streak with 1,360 innings.

Brian Giles singled in a run in the first and Kevin Kouzmanoff added an RBI double in the fourth to give San Diego a 2-1 lead. Chase Headley tried to score on Kouzmanoff’s hit and was tagged out at the plate by Bengie Molina.

Renteria also singled in Travis Ishikawa in the sixth, giving him five RBIs in a game for the eighth time in his career.

Ishikawa had two hits, two RBIs and scored twice for San Francisco.
