The Mets announced on Saturday afternoon that pitching prospect Matthew Allan underwent UCL revision surgery last month. The surgery is essentially like having Tommy John, meaning Allan will miss the entire 2023 season.

This is the third surgery for Allan over the last couple of years that started with Tommy John in May of 2021 and then ulnar nerve transposition January of 2022.

Allan was taken by the Mets in the third round of the 2018 draft, but is yet to pitch since 2019. In 10 1/3 professional innings between Rookie ball and Low-A, Allan owns a 2.61 ERA with 12.2 K/9. He’s considered one of the Mets’ best pitching prospects, but he’s having trouble getting back on the field.
