The New York Yankees’ bullpen has undergone a significant transformation, largely driven by right-hander Mark Leiter Jr.’s remarkable strikeout surge this season. Acquired from the Chicago Cubs on July 30, 2024, Leiter has become a central figure in the Yankees’ renewed pitching strength, exemplifying the team’s talent for reinvigorating pitchers and elevating their game.
Early Struggles and Initial Performance with the Yankees
Mark Leiter Jr. joined the Yankees roster after a midseason trade, exchanging two prospects for the 33-year-old pitcher. His early tenure with the team showed mixed results; over 21 2/3 innings, Leiter recorded a 4.98 ERA and allowed six home runs. Despite this, he demonstrated an impressive ability to strike out batters, tallying 33 strikeouts. The primary issue limiting his success was the amount of hard contact hitters made against his pitches, particularly his sinker, which was expected to serve as a reliable weapon.
Key Adjustments Leading to a Breakthrough Season
The turning point in Leiter’s career came through focused adjustments and coaching. A major factor in his improvement has been the effective use of his splitter, which accounted for 77% of his strikeouts in 2024, down slightly to 66% this season but remaining his dominant strikeout pitch. Under the guidance of pitching coach Matt Blake, Leiter also refined his fastball, significantly curbing the frequency of barreled balls against him. This enhancement not only bolstered his splitter’s effectiveness but contributed to inducing softer contact overall, transforming Leiter into a more dynamic and threatening presence on the mound.
His mastery of the splitter was particularly evident in recent matchups, where hitters struggled to connect, showcasing the culmination of his hard work and tactical pitch improvements.
Impact on the Yankees’ Bullpen and Team Outlook
Leiter’s resurgence is more than individual success; it highlights the Yankees’ bullpen evolution into a formidable part of their competitive arsenal. Alongside other revitalized pitchers such as Luke Weaver, Jake Cousins, and Tim Hill, Leiter’s breakthrough is central to the bullpen’s growing depth and potency. His dominant strikeout ability and improved command enhance the Yankees’ chances as they pursue post-season ambitions this year.

His success resonates beyond baseball, serving as motivation to anyone encountering obstacles in their path.
