Cam Schlittler's curveball left the Boston Red Sox's offense silent in Game 1 of the AL wild-card series (AL WCS) for the New York Yankees on Tuesday night. It helped propel the team to a 9-0 postseason shutout, which also featured a two-home run game from Ben Rice. 

But Schlittler's wicked curve proved to be a lethal weapon against Red Sox hitters. It had nasty written all over it, and it was a weapon of mastery that generated a remarkable 50% whiff rate. 

He continued to end at-bats throwing his curve as a sword. He marked his territory on the mound, with Red Sox hitters fooled by the pitch with its incredible deceptive drop. 

As a practically unhittable pitch, it also helped him continue to dominate against the Red Sox while simultaneously making Yankees history.

Cam Schlittler's elite postseason performance is one for the record books

The AL Cy Young front-runner tossed another one of his gems against the AL East rival Red Sox, repeating history from his successful postseason matchup in 2025. He's yet to give up an earned run against them with 22 strikeouts across 14.1 postseason innings pitched. 

He tossed 6.1 inning scoreless innings and had 10 strikeouts, only two hits, one walk and career-highs in both whiffs (24) and total pitches (117). Fueling the crowd at Yankee Stadium, fans were chanting "MVP" for Schlittler and rewarded him with a standing ovation after he exited the mound. 

Schlittler was known for throwing heaters with his 98 mph fastball during the regular season (44% usage) and only turned to his curve 10% of the time. But his curve made a bold statement against the Red Sox, who had no answers for it. His vicious curve is also a testament to the fact that a pitch doesn't have to be destructive only based on its speed. Overall, his curve was effective in the mid-to-high 80s and was a nightmare for Red Sox hitters.
