LOS ANGELES -- The script is set for the Los Angeles Dodgers to win the NL West.
They'll have ace Clayton Kershaw on the mound in front of their fans against longtime rival San Francisco in the series finale Wednesday night.
"I like our chances," Matt Kemp said. "It would be nice to clinch against these guys."
The Dodgers set up a possible Hollywood ending with a testy 4-2 victory over the second-place Giants on Tuesday night, stretching their division lead to 4 1/2 games.
Justin Turner homered twice, and Kemp had a two-run shot in the first inning, when both benches and bullpens emptied after left-hander Madison Bumgarner hit Dodgers star Yasiel Puig on the left ankle with a pitch.
No punches were thrown, and order was soon restored.
"Tempers flare sometimes," Kemp said. "It's a big game."
Bumgarner said that in trying to throw a cutter, he pulled the ball across and it hit Puig, who ended up on his rear.
"Well, I probably said something first," Bumgarner said. "He's sitting there staring at me."
Puig confirmed that, saying through a translator, "He looked at me and said, 'What are you looking at?'"
The two have a turbulent history dating to a May game in Los Angeles in which Puig homered off Bumgarner, who thought Puig was going too slowly around the bases and yelled at him.
"We had a little back and forth," Puig said. "I'm not sure if this was a continuation of that. I just reacted to what he said."
Bumgarner doesn't see a friendly future for him and Puig.
"I don't think that's in the cards for us," he said.
The Giants' seventh loss in 10 games kept them from clinching a playoff berth after Milwaukee lost at Cincinnati.
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. He tied his career high in victories while throwing a season-high 118 pitches.
"Sometimes I get tired around 100 pitches. Other times I feel good," Greinke said. "Today was one of those when I felt good."
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.
"I was floating around those bases, and the fans were going nuts," Turner said.
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.
"It's a good birthday gift -- hitting a home run and getting a win," Kemp said.
Bumgarner pulled the Giants to 3-2 with his own two-run homer in the third. 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.
"The hitter creates a little drama," Giants manager Bruce Bochy said. "Sometimes you wonder why some guys don't go to first and create the drama. But it was over and Bum settled down."
Kemp, who had words with Puig in the dugout last week at Colorado, came to his defense.
"We needed him in the game," Kemp said. "You don't want anyone to do anything stupid."
Puig also was plunked by Jake Peavy in the first inning Monday night, when the Giants won 5-2 in 13 innings.
Turner is batting .385 with three doubles, three homers and 10 RBIs in 15 games this month.
"I haven't had the opportunity to play meaningful games in September," he said. "It drives you more than when you're playing games that don't mean anything."
Bumgarner's four homers this season are the most by a Giants pitcher since Hal Schumacher hit six in 1934, and his 15 RBIs tied the club record for a pitcher, set by Juan Marichal in 1966.
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. "This is a bad-luck situation because if the bulge moves a little bit more to the other side then I'll be playing, no problem," he said. ... 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. Mattingly said he'd be surprised if Ryu returns before the playoffs.
Giants: Tim Hudson (9-12, 3.52 ERA) has lost his past four outings and has just one win in his past 11 starts as part of the first losing season in his 18-year pro career. He has been bothered by a hip issue.
Dodgers: Kershaw (20-3, 1.80) is tied for the major league lead in victories, and his ERA is the lowest in the majors. The left-hander is 9-2 in 13 home starts with a 1.75 ERA. He owns four shutouts against the Giants.
