LOS ANGELES -- Matt Kemp tweeted on his way to the stadium, "Let's end the season wit a bang!" Did he ever.

Kemp went 4-for-5 with a two-run homer and a career-high three doubles in his final home game of the season, Juan Rivera homered and drove in three runs and the Los Angeles Dodgers beat San Francisco 8-2 Thursday night, pushing the Giants to the brink of elimination in the NL West playoff race.

The Giants open a three-game series at first-place Arizona on Friday and a victory by the Diamondbacks, who were idle Thursday, would eliminate the defending World Series champions.

"We're still in there, I guess, but we've got to win from here on out and hope the other teams don't," Giants starter Madison Bumgarner said. "Everything went wrong this year pretty much."

The Dodgers moved a game over .500 with Hall of Famer Tom Lasorda serving as honorary coach of the team he managed to two World Series titles during his 20-year tenure.

"They played hard, they played great," said Lasorda, who stood next to rookie manager Don Mattingly at the dugout railing for much of the game. "It was a great night. It was fun."

Mattingly said Lasorda spent the game telling him stories.

"He was into the game the whole night," he said.

Fans saluted Hiroki Kuroda as he left the game in the eighth, and they chanted "MVP!" in response to Kemp's offensive show.

"I felt it tonight," Kemp said. "I had my mom sitting there in the front row. It was definitely a happy night."

Kemp's mother, Judy, was in town from her home in Oklahoma and she'll follow her son to San Diego for a three-game series starting Friday.

"I might take her to Arizona, too," Kemp said, laughing. "Every time my mom comes, I play good."

Kemp's two-run homer in the eighth inning off Barry Zito was his 36th, second-best in the NL. The league MVP candidate scored three times to extend his NL lead to 109 runs and and 118 RBIs. His .326 batting average is just shy of league leader Ryan Braun of Milwaukee, who is hitting .330.

"To see a night like that really puts an exclamation mark on what he's been doing all season," Mattingly said.

Kemp said, "I wish we'd been playing like this at the beginning of the season."

He told fans after the game that the Dodgers would make the playoffs next year, something they haven't done since 2009.

"It's sad we're not making the playoffs, but we've been playing great the last two months," Kemp said. "We're going to come back even harder next year. I have all the faith in my team to go out there every day and win."

Kuroda (13-16) allowed two runs and five hits in seven-plus innings to extend his career high in wins. The right-hander struck out four and walked none. By pitching the first inning, Kuroda earned a $175,000 bonus. He gave up a run and two hits as the Giants took a 1-0 lead on Carlos Beltran's two-out homer.

It might have been Kuroda's final start at Chavez Ravine. He becomes a free agent after the World Series and will turn 37 in the offseason. He was the subject of considerable trade speculation before the non-waiver deadline, when he declined to waive his no-trade clause with the only major league team he's pitched for since coming from Japan four seasons ago. Kuroda has spoken of wanting to pitch the final seasons of his career with the Hiroshima Carp in his hometown.

"At this moment, I really don't know (about the future)," Kuroda said through a translator. "It was great to win the last game of the season here."

Bumgarner (12-13) gave up four runs and nine hits in four innings, struck out one and walked none to snap his five-game winning streak. It was the left-hander's shortest outing since he also pitched four innings in a 7-2 loss at Cincinnati on July 30.

Nothing worked for Bumgarner against Kemp.

"It seemed like it didn't matter where I threw it. He was going to find a way to get a knock," Bumgarner said. "It seemed like that this whole series. He's having a career year. When you're facing a good hitter and he's hot, it makes it even harder."

The Dodgers took the lead for good in the bottom of the first on Rivera's two-out, two-run homer. His RBI single in the third made it 3-1.

Dee Gordon's RBI single with two outs in the fourth extended the Dodgers' lead to 4-1.

Waldis Joaquin gave up a bases-loaded walk to Rod Barajas, the first batter he faced in the fifth, before Jamey Carroll's fielder's choice grounder increased the Dodgers' lead to 6-1.

The Giants' other run came on Pablo Sandoval's 23rd homer on Kuroda's first pitch of the seventh.
