Marcus Semien Endures Career-Worst Season With New York Mets

Marcus Semien endured the worst season of his career in 2026 after being acquired by the New York Mets for Brandon Nimmo. The 35-year-old second baseman posted a career-low 74 wRC+ and a -0.5 fWAR across 547 plate appearances, suffering significant declines in bat speed, exit velocity, and defensive range. With $46 million remaining on his contract through 2028, Mets leadership has declined to name him the starting second baseman for 2027, leaving his roster status uncertain.
