Clayton Kershaw finished with a major league-leading 2.53 ERA, Adrian Gonzalez singled in the go-ahead run in the sixth inning, and the Los Angeles Dodgers defeated the San Francisco Giants 5-1 to end their season on Wednesday, a day after being eliminated from playoff contention for the third straight year by the NL West champions.

Kershaw (14-9) allowed one run and three hits in eight innings, struck out eight and walked three in his 33rd start, tying a career high. The reigning NL Cy Young Award winner recorded 229 strikeouts, one behind NL leader R.A. Dickey of the New York Mets. The left-hander became the first pitcher to lead the league in ERA in consecutive seasons since Arizona's Randy Johnson in 2001-02.

Kershaw became the first Dodgers pitcher to do so since Sandy Koufax accomplished the feat from 1962-66.

Gonzalez finished on a 15-game hitting streak, longest on the team he joined from Boston at the July 31 trade deadline. He drove in Andre Ethier, who doubled, with two outs to give the Dodgers a 2-1 lead. They tied the game 1-1 on Kershaw's RBI single in the fifth -- the Dodgers' first hit off Giants starter Ryan Vogelsong, who also retired his first 10 batters.

Kenley Jansen pitched the ninth to earn his 26th save in 32 chances.

Clay Hensley (4-5) gave up one run and two hits in one inning to take the loss for the Giants, who open the NL division series on Saturday against Cincinnati.

Giants catcher Buster Posey went 0 for 2, finishing the regular season with a .336 average to claim the NL batting title. He's the first Giants player to win it since Barry Bonds in 2004 and the first Giants catcher to do so. The last catcher to win the NL title was Boston's Ernie Lombardi, who hit .330 in 1942.

The Dodgers made it 5-1 in the eighth on homers by Alex Castellanos and Juan Rivera, who had a two-run shot.

San Francisco led 1-0 in the fourth on Posey's RBI groundout to shortstop, scoring Marco Scutaro, who singled to extend his hitting streak to 20 games.

Dodgers slugger Matt Kemp struck out twice to end the season 0 for 10 with seven strikeouts in the three-game series, which the Dodgers won, 2-1, giving them four straight series victories for the first time this season.

Vogelsong allowed one run on two hits in five innings, struck out seven and walked one.
