Overview

• Frankie Montas has been moved from the starting rotation to a multi-inning relief role after posting a 6.38 ERA since his late-June return from injury.
• Veteran right-hander Paul Blackburn was recalled from Triple-A Syracuse and will join the bullpen upon activation.
• Top prospect Nolan McLean will make his major league debut Saturday at Citi Field, stepping into the rotation spot vacated by Montas.
• The timing of McLean’s promotion was structured to preserve his rookie eligibility under MLB’s service-time rules.
• Justin Hagenman is expected to be optioned to Triple-A to open a roster spot for Blackburn’s reinstatement.
