The Los Angeles Dodgers took a 2-0 World Series lead Saturday night after defeating the New York Yankees 4-2.

Yoshinobu Yamamoto allowed one hit over 6 1/3 innings, Freddie Freeman homered for the second straight night and Los Angeles hit three early longballs off Yankees starter Carlos Rodon.

But Dodgers superstar Shohei Ohtani injured his left arm during the seventh inning when he was caught stealing second base. The severity of the injury wasn't immediately clear.

Ohtani clutched his left forearm after being tagged by shortstop Anthony Volpe for the final out in the inning on a feet-first slide. He laid near the bag for a couple minutes before being tended to by trainers and leaving the field.

Ken Rosenthal of Fox Sports reported from the Dodgers dugout that the issue was with Ohtani's left shoulder.

Tommy Edman and Teoscar Hernandez also went deep for the Dodgers.

After the Yankees closed to 4-2 on Giancarlo Stanton's RBI single in the ninth against Blake Treinen, Alex Vesia relieved with the bases loaded and retired pinch-hitter Jose Trevino on a first-pitch flyout for the save.

Yamamoto allowed Juan Soto's third-inning homer, then retired his last 11 batters and 15 of his final 16.

Soto also singled in the ninth and scored on Stanton's one-out hit off the third-base bag. Jazz Chisholm Jr. singled and Anthony Rizzo was hit by a pitch, loading the bases. Treinen then struck out Anthony Volpe before Vesia relieved.

Game 3 on Monday in New York

Game 3 is Monday night at Yankee Stadium. Forty-five of 56 teams holding 2-0 World Series leads have gone on to win the title.

New York's Aaron Judge went 0 for 4 with three strikeouts and is hitting .150 with six RBIs and 19 strikeouts in 40 post-season at-bats.

Soto's tying homer on an inside fastball was the only run Yamamoto allowed in two starts and 13 1/3 innings against the Yankees this year. The rookie left to a large ovation and gave the very slightest tip of his cap to fans when he walked to the dugout.

Yamamoto joined the Dodgers last December for a $325 million, 12-year contract, a record for pitchers, teaming with Ohtani to create record interest in Major League Baseball back in Japan.

Yamamoto was sidelined from June 15 to Sept. 10 because of a strained rotator cuff and this was his finest start since the injury.

In his longest outing since his start in the Bronx, Yamamoto struck out four and walked two with a five-pitch array that included curveballs, splitters, sliders and cutters. He improved to 2-0 in four post-season starts.

He threw his best regular-season game at Yankee Stadium in June when he allowed three hits over seven shutout innings. Hernandez had three homers and nine RBIs over that three-game series.

A night after Freeman hit the first walk-off grand slam in Series history to transform a 3-2 deficit with two outs in the 10th inning into a 6-3 win, Edman put the Dodgers ahead with a solo shot in the second.

After Soto tied the score, Mookie Betts singled with two outs in the bottom half and Hernandez, in a 3-for-27 slide, homered into the right-centre pavilion.

Freeman, who before Friday hadn't gone deep since Sept. 16, was greeted with huge cheers before each plate appearance. He worked the count full and also homered to right-centre.

Playing on a sprained right ankle, Freeman has homered in four straight Series games dating to Atlanta's last two games against Houston in 2021. That is one shy of the record held by the Astros' George Springer.

All three Dodgers homers came on fastballs from Rodon, whose 31 longballs allowed during the regular season tied for second-most in the major leagues. Los Angeles had back-to-back Series homers for just the second time, after Pedro Guerrero and Steve Yeager connected against Yankees lefty Ron Guidry for a 2-1 win in Game 5 in 1981.

Rodon allowed four runs and six hits in 3 1/3 innings.

Los Angeles took a 2-0 Series lead for the first time since 1988, when Kirk Gibson's walk-off homer against Oakland's Dennis Eckersley won the opener and Orel Hershiser followed with a three-hit shutout. The Yankees are 0-2 for the first time since 2001, when they rebounded to win three straight at home and lost Games 6 and 7 at Arizona.
