SAN FRANCISCO (AP) — Madison Bumgarner struck out eight and took a share of the major league lead with 18 wins, and the San Francisco Giants moved within one game of NL West-leading Los Angeles by beating the Dodgers 9-0 on Friday night.

Pinch-hitter Travis Ishikawa splashed a three-run homer into McCovey Cove, and Brandon Crawford hit a two-run drive in the fifth to help Bumgarner win his fifth straight start. Buster Posey and Crawford hit RBI doubles in the first as the Giants jumped on Hyun-Jin Ryu (14-7).

The Dodgers’ left-hander exited after only one inning because of irritation in his pitching shoulder.

San Francisco, which leads the NL wild-card race, is one game back of Los Angeles for the first time since Aug. 4. The Giants have won a season-best 10 straight home games after handing the Dodgers their fifth shutout loss.

Bumgarner (18-9) reached 200 strikeouts for the first time in his career when he fanned Scott Van Slyke in the second. The lefty is tied with Dodgers Sunday starter Clayton Kershaw, Cincinnati’s Johnny Cueto and the Cardinals’ Adam Wainwright for most wins in the majors.

Los Angeles lined up its top starters for this series, while Giants manager Bruce Bochy opted to keep his pitchers on their regular schedule since things have been working well so far in September.

The Dodgers had the best road record in baseball and swept the Giants in three games at AT&T Park from July 25-27 — outscoring San Francisco 17-4.

“It’s live theater every night, we just don’t know the ending here,” Dodgers manager Don Mattingly said of the race.

Posey hit an RBI double in the first that sent the orange towel-twirling fans into a frenzy. Hunter Pence followed with a run-scoring single, then Joaquin Arias added an RBI single.

San Francisco’s home winning streak is its longest since an 11-game run from July 7-25, 2003, which is the best in the 15-year history of AT&T Park.

Bumgarner needs two wins over his final three starts to become the Giants’ first 20-game winner since John Burkett (22) and Bill Swift (21) in 1993. Bumgarner has 207 strikeouts, most in a season by a San Francisco left-hander.

Ishikawa’s second career pinch-hit homer was the 102nd into the water and 67th by a San Francisco hitter.

Trainer’s Room

Dodgers: LHP Paco Rodriguez, on the disabled list since Aug. 4 with strained muscle below his pitching shoulder, threw a simulated game that went well. If he bounces back fine, Mattingly said a decision could be made as soon as Saturday about activating Rodriguez.

Giants: 1B Brandon Belt took batting practice a day after being medically cleared from a concussion. OF-1B Michael Morse missed his 10th straight game with a strained left oblique. He took some pregame swings but still needs at least a couple of days.

Up Next

Dodgers: RHP Zack Greinke (14-8, 2.73 ERA) puts his unbeaten mark against NL West opponents this season on the line in the middle game of the series. He is 9-0 in 12 starts vs. the division.

Giants: RHP Tim Hudson (9-10, 3.12) makes his 16th career start against the Dodgers and second this season, trying to end a two-start skid.
