SAN DIEGO -- The Los Angeles Dodgers slugged five home runs to defeat the San Diego Padres 8-4 on Friday night.

The win pushed the Dodgers' lead over the San Francisco Giants to a season-high 7.5 games in the National League West.

Mike Bolsinger (6-3) won his third straight start but for the first time since July 29. Bolsinger, who pitched five innings and allowed three runs on two hits and two walks, spent the last month in Triple-A Oklahoma City.

Bolsinger beat the Padres for the second time this season, throwing eight innings of shutout ball against them on May 23.

Los Angeles rallied twice in the game and then pulled away with a five-run sixth. That inning included a two-run, pinch-hit homer by Justin Ruggiano, a two-run shot by first baseman Adrian Gonzalez and a solo blast from second baseman Chase Utley.

Marcus Mateo (1-1), who pitched to two batters in the sixth, got the loss.

The Dodgers' other homers, both solo, came from left fielder Carl Crawford in the first and right fielder Scott Schebler in the second. It was Schebler's first major league homer.

Los Angeles, the NL-leader with 162 home runs, has won nine of its last 11 games.

The Padres' James Shields had a rocky start. He collected a season-high six walks in five innings, charged with three runs and three hits. He struck out four.

San Diego's Brett Wallace hit his third pinch-hit homer of the season in the eighth. It was contest's eighth homer, which tied the single-game mark at Petco Park.

Shields surrendered his second lead of the game in the fifth inning when the Dodgers pushed the tying run across.

Shortstop Jimmy Rollins scored to make it 3-3 when third baseman Corey Seager reached on a fielder's choice. Rollins had doubled and advanced on walks to first baseman Adrian Gonzalez and second baseman Chase Utley.

In the third inning second baseman Jedd Gyorko hit a double that became a home run. It was initially thought the ball ricocheted off the top of the left-field wall, but after a 1:50 review, it was ruled a homer, putting the Padres ahead 3-2.

The Padres seized a 2-1 lead on right fielder Matt Kemp's two-run homer in the first inning. Kemp's blast, his 17th of the year, drove in third baseman Yangervis Solarte after he walked.

Shields has been haunted by the home run ball this season and that was true against the Dodgers.

Left fielder Carl Crawford gave Los Angeles a 1-0 lead in the first when hitting a homer deep in the right-field bleachers.

In the second, right fielder Scott Schebler redirected a Shields changeup 443 feet for a solo homer to tie the game, 2-2. It was the 28th home run allowed by Shields, tied for the third-most in major leagues.
