Overview

• Right-hander Nolan McLean will make his major-league debut Saturday at Citi Field, filling the rotation spot vacated by Frankie Montas.
• Frankie Montas was officially shifted to the bullpen after posting a 6.38 ERA over seven starts this season.
• McLean arrives from Triple-A Syracuse with a combined 2.45 ERA, 127 strikeouts and a 1.13 WHIP across 113⅔ minor-league innings in 2025.
• The 24-year-old prospect features an elite mid-80s sweeper but carries a 10.6 percent walk rate and tougher splits against left-handed hitters.
• Veteran Paul Blackburn was unexpectedly recalled to provide multi-inning relief after Justin Hagenman was optioned, boosting bullpen depth.
