LOS ANGELES — Yoshinobu Yamamoto walked back to his dugout and made the slightest tip of his cap to cheering fans. He left Japan for moments like this, an opportunity to put the Los Angeles Dodgers in control of the World Series.
Yamamoto allowed one hit over 6 1/3 innings, Freddie Freeman homered for the second straight night and Los Angeles beat the New York Yankees 4-2 on Saturday for a 2-0 Series lead.
But the Dodgers will head to New York uncertain whether Shohei Ohtani can play after their biggest star partially dislocated his left shoulder on a slide at second base.
''We're going to get some tests at some point tonight, tomorrow, and then we'll know more in the next couple days,'' manager Dave Roberts said. ''The strength was great. The range of motion good. So we're encouraged.''
Tommy Edman and Teoscar Hernández also went deep off starter Carlos Rodón, who tied a Yankees World Series record by allowing three home runs.
New York was held to one hit before the ninth, when the Yankees closed to 4-2 on Giancarlo Stanton's one-out RBI single against Blake Treinen. Anthony Volpe struck out with the bases loaded, and Alex Vesia came in to retire pinch-hitter Jose Trevino on a first-pitch flyout for his first postseason save.
''Thinking back to my front yard at my house, that's what we would envision,'' Vesia said.
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.
