Earlier today, the Mets announced that Kodai Senga will not make his scheduled rehab tonight for the Binghamton Rumble Ponies after experiencing ulnar nerve irritation. The club has not provided any further details at this time.
This is the latest injury setback for the Mets’ right-hander, who came into this year with a main goal of avoiding injuries. Senga, who was putting together a strong 2025 campaign before an ill-timed injury derailed his season in June, was placed on the IL back on April 28 with lumbar spine inflammation. He has made three rehab starts so far, posting a 6.00 ERA across 12 innings pitched in Port St. Lucie (one start, 5.40 ERA) and Syracuse (two starts, 6.23 ERA).
The hope was that his June 3 rehab assignment would be his final test before a return to the majors, but the club opted to give him another outing given his subpar results and diminished velocity. He also struggled with his command in each of his three starts, walking five across batters and ultimately needing 235 pitches to get through his three outings (20 pitches per inning on average).
This news casts some further doubt over the kind of production the club can expect from the right-hander over the final year-and-a-half of his five-year contract. Senga was the 2023 National League Rookie of the Year runner-up and seemed poised to be a star in the league, but injuries have ultimately negatively defined his time in the major leagues.
Following Senga’s latest setback, the Mets will be forced to look for solutions in their rotation. Right now, the club can count on Christian Scott, Nolan McLean, and Freddy Peralta to pitch relatively reliably every five games, but beyond that, Sean Manaea is still a question despite some encouraging outings as of late, and David Peterson remains stuck in the bullpen after his struggles as a starter. The club will need a fifth starter on June 13, with some internal options including prospects Zack Thorton (who debuted earlier this year) and Jack Wenninger.
