LOS ANGELES (AP) — Justin Turner homered twice and Matt Kemp had a two-run shot in a testy first inning, helping the Los Angeles Dodgers beat the second-place San Francisco Giants 4-2 to stretch their NL West lead to 4 1/2 games Tuesday night.

The Giants’ seventh loss in 10 games kept them from clinching a playoff berth after Milwaukee lost at Cincinnati.

The Dodgers can win the division title behind ace Clayton Kershaw with a victory in the series finale Wednesday night.

The game got off to a rocky start when both benches and bullpens emptied after left-hander Madison Bumgarner hit Dodgers star Yasiel Puig in the left foot with a pitch. No punches were thrown and order was soon restored.

Zack Greinke (16-8) extended his mastery of the Giants, improving to 5-0 against them this season. He is unbeaten in seven career starts against San Francisco.

The right-hander allowed two runs and six hits in eight innings, striking out five and walking none. He retired 17 of his final 19 batters.

Kenley Jansen pitched the ninth to earn his 44th save.

Bumgarner (18-10) had been dominant at Dodger Stadium with a 7-2 career mark coming in, but he was stymied in pursuit of his fourth straight win there. He gave up four runs and six hits in 7 1/3 innings, striking out five and walking none.

Turner homered into the left-field pavilion in the eighth for the second time in the game, chasing Bumgarner.

After the tension subsided in the first, Puig took first base and Kemp celebrated his 30th birthday by hitting his 24th homer, extending the Dodgers’ lead to 3-0. Turner got things started with his first career leadoff shot in the first.

Bumgarner pulled the Giants to 3-2 with his own two-run homer in the third after Juan Perez grounded into a fielder’s choice to third base. The pitcher pumped his right arm and yelled as he rounded first base.

Puig came in hitting .300 against Bumgarner, but the Cuban outfielder was hitless in three at-bats with two strikeouts.

After getting hit, Puig quickly tailed plate umpire Adrian Johnson toward the mound, yelling at Bumgarner. The pitcher chucked his glove behind him and gestured with both hands as if to say, “Bring it on.”

Johnson pushed Puig away, and Kemp got in front of Puig before Dodgers manager Don Mattingly restrained his emotional star.

Puig also was plunked by Jake Peavy in the first inning on Monday night, when the Giants won 5-2 in 13 innings.

Trainer’s Room

Giants: OF Angel Pagan (inflamed nerve in lower back) will have season-ending surgery to repair a bulging disk in his back Thursday in Los Angeles. ... OF Michael Morse has shown some improvement with a strained oblique and might be ready for the upcoming San Diego series.

Dodgers: LHP Hyun-Jin Ryu (shoulder inflammation) is playing catch while slowly increasing distance and velocity. “He’s moving forward and not having any complaints afterward,” Mattingly said, adding that he’d be surprised if Ryu returns before the playoffs.

Up Next
