Mets ace Kodai Senga will not return for the remainder of the regular season after experiencing tightness in his triceps during a rehab start with Triple-A Syracuse. Originally hopeful for a return, Senga has been ruled out for the regular season, leaving the team with uncertain prospects for his participation in the postseason. Despite this setback, Senga’s recent performances in rehab outings indicated he was making progress, including a sharp one-inning appearance where he struck out two batters. The Mets continue to remain optimistic about his potential return for the playoffs, though definitive timelines remain unclear as Senga focuses on getting back to full strength.
