Hayden Mullins
Pitching scouting report · 80Grade
Scouting summary
Mullins has a realistic path to the majors through a multi-inning relief role, where his fastball quality and varied breaking-ball mix can play up in shorter bursts. His ceiling is a lower-leverage or seventh-inning relief job, with a chance to cover multiple innings if the walk rate improves and one secondary becomes consistently above average. The 2025 performance was strong, while the 2026 strikeout production remained impressive but came with enough baserunners to reinforce the command concern. A durable body and starter experience provide a reasonable floor, but the current combination of below-average control and uneven secondaries makes a sustained rotation role unlikely.
