Devin Williams, the New York Yankees' newly acquired closer, has struggled early in the 2025 season, admitting he hasn't felt 100%. After yielding three runs in a recent outing, he was pulled despite starting the ninth inning with a four-run lead. Manager Aaron Boone suggests Williams needs more game reps to find his rhythm, as the reliever has pitched in only four of the Yankees' first 12 games this season. Historically, Williams has had slow starts, posting high OPS and ERA numbers during March-April. His changeup, a key part of his arsenal, hasn't been sharp, contributing to his struggles. Boone remains optimistic about Williams returning to form, citing that his execution is close to what is needed.
