Overview
- The Mets scratched Kodai Senga from a scheduled Double-A rehab start on Tuesday because of ulnar nerve irritation in his right upper arm, a team announcement reported by multiple outlets.
- Senga described the sensation as "relatively minor," threw and played catch under team supervision, and the club said it would monitor him day to day.
- After the pause he resumed his rehab assignment and threw six innings with one run allowed and five strikeouts in a Double-A start reported on Thursday, with no visible arm issues on the mound.
- The club remains cautious because Senga’s three earlier rehab outings showed control problems and his 2026 major-league results have been poor, so the Mets are treating any new arm reaction as a meaningful stoppage.
- Recurring injuries and uneven performance have intensified questions about Senga’s durability and long-term fit in New York, and his availability will shape roster moves and the team’s rotation strategy this summer.
