Kodai Senga’s 2025 season with the New York Mets was a jarring tale of two halves. An All-Star caliber first 13 starts, where he posted a dominant 1.47 ERA, gave way to a catastrophic collapse after a mid-season hamstring injury. Upon his return, Senga was ineffective, finishing his final nine starts with a 6.18 ERA and 0-3 record. This wasn't a temporary slump; it was a systemic breakdown rooted in around 2 MPH velocity loss on his fastball, mechanical compensations from the injury, and a resulting decline in the effectiveness of his entire arsenal.
The precipitous decline has left the Mets in a bind.
