San Diego ? Phil Nevin homered in consecutive at-bats, and Humberto Quintero, Brian Buchanan and Brian Giles also connected, leading the San Diego Padres past the Kansas City Royals, 7-5, Friday night.

The five homers were the most in a game in nearly two seasons for the Padres, who griped early this season about the spacious outfield at their new $458 million ballpark.

Jake Peavy (5-2) returned from the disabled list and combined with five relievers on a seven-hitter. The 22-year-old right-hander, out since May 20 because of a strained right forearm, lowered his earned-run average to 1.98 by holding the Royals to one run and three hits in 51/3 innings. He struck out six and walked one.

At the time of his injury, Peavy led the NL with a 2.01 ERA.

Peavy was pulled after giving up Ken Harvey’s shot into the home-run porch down the right-field line with one out in the sixth, his ninth. Harvey finished with three hits.

The Royals scored four times in the ninth on Matt Stairs’ two-run homer off Jay Witasick, Alberto Castillo’s RBI single and a wild pitch by Trevor Hoffman.

Hoffman got two outs for his 19th save in 21 chances.

Dennys Reyes (2-3) allowed the first

three Padres homers, all solo shots. Shawn Camp gave up the last two, including Giles’ three-run shot into the porch to cap a five-run sixth.

Nevin complained the most about how the ball didn’t carry well to the parts of Petco Park he likes to hit to, right-center and right field. The gap in right-center is the deepest part of the ballpark at 411 feet.

San Diego's Brian Giles gazes at the flight of his three-run home run in the sixth inning against Kansas City. The Padres beat the Royals, 7-5, Friday in San Diego.

His first homer Friday night sailed into the Padres’ bullpen beyond the fence in center field leading off the second inning, and he lined his second shot into the seats in left leading off the fourth. His 13th and 14th of the season, they were both on waist-high fastballs.

It was Nevin’s 10th career multihomer game, and first since July 31, 2002, at Wrigley Field. That also was the Padres’ last five-homer game.

San Diego’s previous home-run high at Petco was two, which they had accomplished five times.

Quintero, a rookie catcher, homered to left with one out in the sixth, his second. Buchanan, pinch-hitting for Peavy, hit Camp’s second pitch into the second deck in left. Giles’ shot, his 12th, landed in the first row of the home-run porch.

Reyes allowed three runs and eight hits in 52/3 innings. He struck out six and walked two.

Notes: Royals 1B Mike Sweeney sat out because of a stiff lower back. … The Padres have sold 2,560,690 tickets for their first season in Petco Park, enough to break the club’s home attendance record of 2,555,901 set in 1998, the season San Diego went to the World Series and the last time it had a winning record.
