Wandy Peralta
Another name, another Yankees farewell that didn't go as planned. Peralta landed on the IL with a triceps injury in mid-September, meaning his final game in pinstripes came and went without fans having any ability to acknowledge him.
Peralta became a fantastically weird Yankee after arriving in the Mike Tauchman trade in early 2021. The rubber-armed lefty with a bag of a million tricks pitched in all five games of the 2022 ALDS, and did so effectively. He allowed two runs in Game 3 while trying to complete a multi-inning appearance (they were inherited runners that scored under Clarke Schmidt's watch). No matter; he rebounded and closed both Games 4 and 5. If not for his base runners, the series could've ended in four games, sure, but it's not shocking that, in moments of great triumph, Peralta still found a way to mess with timing.
The 32-year-old fended off the regression monster in this season's second half, and his 2.83 ERA never rose to match his 5.05 (!) FIP. Peralta's control was off in 2023, but it never came back to bite him, and if his triceps issue doesn't turn out to be serious, he'll have played his way out of the Yankees' price range entering free agency. It's certainly possible that said regression hits all at once in 2024, and hopefully someone pays him on performance and not theoretical results. He deserves a multi-year pact. It won't be with the Yankees.
