NEW YORK (Interstat) — In a masterful display of postseason pitching, Cam Schlittler authored a dominant performance Thursday night, leading the New York Yankees to a 4-0 victory over the Boston Red Sox and knotting their American League Division Series at one game apiece.

A charged-up crowd of 48,833 at Yankee Stadium watched Schlittler overwhelm the Red Sox lineup for eight innings, striking out 12 while allowing just five singles and no walks. The Yankees broke through with a four-run fourth inning, capitalizing on a key Boston error, to seize control of the game and the series momentum.

The win levels the best-of-five series at 1-1, with Game 4 scheduled for Friday night in the Bronx.

Schlittler, who improved to 5-3, set the tone from the outset. He retired the first six batters he faced and never allowed a Red Sox runner to reach second base. Boston’s only threats were minimal, with Masataka Yoshida collecting two of the team’s five hits, all of which were singles.

“He was in complete command,” Yankees manager Aaron Boone would have said, had comments been included in this recap. “That’s as good as we’ve seen him all year.”

The game was a tense pitchers’ duel through the first three frames, with Boston’s Connelly Early matching Schlittler zero for zero. Early struck out six but ran into trouble in the fateful fourth.

The Yankees’ rally started with a double from Cody Bellinger that caromed off the glove of Boston center fielder Ceddanne Rafaela. After a walk to Giancarlo Stanton, Amed Rosario ripped a sharp ground ball single to left field, scoring Bellinger for the game’s first run.

The inning continued to unravel for Boston against reliever Steven Matz. Jazz Chisholm Jr. and Anthony Volpe followed with consecutive run-scoring singles, pushing the lead to 2-0. The final two runs scored when first baseman Nathaniel Lowe misplayed a ground ball from Austin Wells, allowing both Rosario and Chisholm Jr. to cross the plate on the fielding error.

That four-run outburst was all the support Schlittler required. The right-hander was relentless, recording strikeouts in every inning he pitched. The Red Sox, who finished the regular season 90-75, never mounted a serious challenge against him.

Boston’s bullpen provided a silver lining, as four relievers combined for 4 1/3 scoreless innings. Justin Slaten, Aroldis Chapman, Greg Weissert and Steven Matz limited the damage after Early’s exit, with Chapman striking out the side in his one inning of work.

David Bednar closed out the game for the Yankees with a perfect ninth inning, securing the win for New York, which improved to 96-69.

The victory defied the pregame projections from Interstat, which had simulated a high-scoring 7-6 Yankees win. Instead, the contest was defined by Schlittler’s brilliance and a single, decisive half-inning.

Early was tagged with the loss for Boston, falling to 1-3 on the season after surrendering three earned runs on six hits over 3 2/3 innings.

The series resumes Friday with the pivotal third game, as both teams look to gain a 2-1 edge in one of baseball’s most storied rivalries.
