Frankie Montas accepted a bullpen role with the Mets, telling manager Carlos Mendoza he’ll do whatever helps the team win, even if he’d rather be in the rotation. The move comes as New York tries to stabilize a shaky rotation while Montas rebuilds form after a lat strain and inconsistent return. The Mets will fill his rotation slot with Nolan McLean, a 24-year-old right-hander making his MLB debut against Seattle. Montas has a 3-2 record with a 6.38 ERA in eight appearances (seven starts), and his bullpen appearance was his first since the move. Clay Holmes remains in the mix as a starter-by-default, while the Mets juggle a lineup crunch at third with Mark Vientos, Brett Baty and Ronny Mauricio competing for time as Starling Marte sits on occasion. Montas emphasized his readiness to contribute in multi-inning bursts or as needed in extra innings. The Braves series adds urgency to the Mets’ season as they chase consistency behind a bullpen-leaning plan that hinges on holding opponents in check late and squeezing more quality innings from their depth.
