LOS ANGELES — Justin Turner hit a three-run homer with two outs in the bottom of the ninth inning, and the Los Angeles Dodgers beat the Chicago Cubs 4-1 on Sunday to take a 2-0 lead in the NL Championship Series.

Turner drove in every run for Los Angeles, going the other way for a tying single in the fifth before sending a long shot to center field off John Lackey in the ninth. A fan wearing a blue Dodgers jersey reached over a railing to catch the ball on the fly.

Turner’s second homer of the postseason ended another dramatic night for the Dodgers, who remained unbeaten in these playoffs and moved within two wins of their first World Series appearance since 1988.

And the red-bearded slugger even did it on the 29th anniversary of Kirk Gibson’s pinch-hit, walk-off homer to beat Oakland in the opening game of the Dodgers’ last World Series victory.

“It’s very cool, and J.T., we were talking about it in there after the game,” Dodgers manager Dave Roberts said. “Twenty-nine years to the day. It was special. Our guys feel it.”

Game 3 in the best-of-seven series is Tuesday night at Wrigley Field in Chicago. Midseason acquisition Yu Darvish starts for the Dodgers against Kyle Hendricks.

Yasiel Puig drew his third walk of the game leading off the ninth, and Charlie Culberson bunted him to second. After Brian Duensing struck out pinch-hitter Kyle Farmer, Chicago manager Joe Maddon went to the bullpen for the 38-year-old Lackey, who pitched on consecutive days for the first time in his 15-year career.

Lackey got the call over All-Star closer Wade Davis, and the veteran starter walked Chris Taylor on six tense pitches.

Turner stepped up and ended it with his long drive — the fourth playoff homer of his career.
