John Klein
Pitching scouting report · 80Grade
Scouting summary
John Klein projects as a middle reliever depth candidate for the Minnesota Twins professional bullpen in 2026. His fastball-splitter-cutter combination generates potential effectiveness in shortened relief outings where pitch selection concentration and maintained velocity execution minimize command consistency concerns. The Twins protected Klein from Rule 5 Draft eligibility with apparent intentions of deploying him in relief roles emphasizing his primary offerings while de-emphasizing less-developed secondary pitches. Conservative projection suggests Klein could develop into a functional mid-to-late-inning reliever providing organizational depth, particularly given the Twins' critical bullpen depth needs following their 2025 trade deadline dismantling. Klein's work ethic, demonstrated improvement trajectory, and professional makeup suggest potential Opening Day roster competition for mid-leverage relief roles should he consolidate command development and optimize pitch mix utilizatio
