Mets Shift Kodai Senga to Bullpen in Bid to Reboot His Season

The Mets moved right-hander Kodai Senga from the rotation to the bullpen after a dramatic downturn dating back to last year, highlighted by a lumbar injury and a rough 2026 stretch that included a 27 earned runs in 16 innings since returning. Despite a strong spring, his season has cratered with high walks, homers, and ERA spikes. The Mets will patch the rotation with Nolan McLean, Freddy Peralta, David Peterson and Sean Manaea while evaluating whether a relief role can salvage Senga’s value or lead to further roster moves.
