Montero will be promoted and start Monday in place of Jacob deGrom, whose turn on the rotation os being skipped due to fatigue and to work on mechanical issues, ESPN New York reports.
Montero opened the season at Triple-A Las Vegas but was demoted due to poor performance after he posted a 4.60 ERA in 16 starts with the 51s. With his prospect status diminished and his career possibly hanging by a thread, Montero turned it around at Double-A Binghamton, posting a 1.70 ERA in eight starts, albeit with 19 walks in 47.2 innings pitched. With the rosters expanding Thursday, look for Montero to remain with the Mets as a spot-starter and bullpen arm.
