Do the Yankees finally have their shutdown closer?

Over the past two years, Holmes has been a critical asset for the Yankees, but this season could be his best yet. He ranks in the 99th percentile in both walk and ground ball rates, with an expected ERA (xERA) of 2.47. While he has benefitted from some fortunate situations to maintain his flawless ERA, even an ERA close to his xERA would be highly satisfactory for the Yankees.

Holmes’ Pitch Arsenal and Impact

Holmes’ effectiveness is largely due to his diverse pitching arsenal, consisting of a sinker, slider, and sweeper. His sinker, thrown at an average speed of 96.3 mph, has allowed a .297 batting average this year. In contrast, his slider has been untouchable, with opposing batters hitting .000 and a 52.6% whiff rate alongside a 30% put-away rate.

The sweeper, used less frequently at 12.1%, has also proven effective, securing four strikeouts from just 24 pitches. The contrast between his slider’s vertical movement and the sweeper’s horizontal movement creates a challenging dynamic for hitters, enhancing Holmes’ effectiveness. His sinker and sweeper both generate significantly more movement than average, contributing to his success.

Since the era of Aroldis Chapman, the Yankees have been in search of a reliable closer. This season, Holmes is emerging as a dominant force in the bullpen, echoing the team’s knack for discovering undervalued talent in relief roles, as evidenced by Holmes and Ian Hamilton.
