After demoting struggling starter Frankie Montas, the New York Mets will call up top prospect Nolan McLean to replace him.

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.

The New York Mets needed to make a change in the pitching rotation, and manager Carlos Mendoza has announced his bold decision.
