The New York Mets are promoting top pitching prospect Nolan McLean for his MLB debut on Saturday, filling the rotation spot left by Frankie Montas. This strategic timing allows McLean to retain rookie eligibility for next season and potentially earn the Mets compensatory draft picks through the league’s Prospect Promotion Incentive program, while he boasts impressive minor league stats, including a 2.45 ERA and high strikeout rate.
