Mets pitching prospect Matt Allan said on Saturday that after having Tommy John surgery in May, he had another operation in January to repair a nerve issue, as Tim Healey of Newsday reported. Mike Puma of the New York Post clarified that it was ulnar transposition.
Allan said that he’ll begin throwing in March. The likelihood of him pitching in games this season is small — in fact, as Puma pointed out, it was already small even before this latest operation.
As Healey mentioned, ulnar transposition is common for players who have had Tommy John surgery. Jacob deGrom and Steven Matz are just two examples of players who have had it.
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.
Still, he is just 20 years old and is slowly but surely making progressions on returning to the mound. The Mets likely expected that he’d have a lot more professional innings under his belt by now, but they’ll hope his latest surgery gets him back on the right path.
