As feared, Mets right-hander Frankie Montas will have Tommy John surgery on Tuesday and likely will miss the entire 2026 season, the New York Post reported.

Montas, 32, began his first season with the Mets on the 60-day injured list with a right lat strain and ended the campaign on the 60-day IL with a UCL strain in his right elbow.

Signed to a two-year, $34 million contract in the offseason, Montas made just nine appearances (seven starts) and finished 3-2 with a 6.28 ERA this season.

Montas is 47-48 with a 4.20 ERA in 169 career games (136 starts) with the Chicago White Sox (2015), then-Oakland Athletics (2017-22), New York Yankees (2022-23), Cincinnati Reds (2024), Milwaukee Brewers (2024) and Mets.

The second year of Montas' deal with the Mets is a $17 million player option for the 2026 season.
