The Mets promoted 22-year-old stud pitching prospect Jonah Tong to Syracuse on Sunday — after he dominated at Double-A Binghamton with a 1.59 ERA over 20 starts — but the expectation within the organization is the right-hander won’t be a candidate to pitch in the major leagues this season.

On Tuesday, manager Carlos Mendoza announced that change is coming for the pitching staff. Starter Frankie Montas is moving to the bullpen amid struggles that have plagued him since he was called up in late June.
