The Mets placed right-hander Frankie Montas on the 15-day IL on Saturday with a UCL injury in his right elbow. In a corresponding move, the club recalled right-hander Huascar Brazobán from Triple-A Syracuse.

The righthander, who signed a two-year, $34 million contract in the offseason, has pretty significant damage to the right UCL.

ATLANTA — A turbulent season for Frankie Montas has come to a premature end. The right-hander has a “significant” ulnar collateral ligament in his throwing elbow, and will be out for the rest of the season. Tommy John or an internal brace procedure is likely, which would also sideline him for 2026 as well.
