Scouting Report

Updated May 19, 2026

Janson Junk, 30-year-old right-handed pitcher for the Miami Marlins, is experiencing a breakout 2026 season. Through 8 starts (44.1 innings), he owns a 3.25 ERA, 1.11 WHIP, and 33:10 K:BB ratio. Most notably, he achieved a dramatic walk rate improvement to 2.9% (best in MLB among pitchers with 80+ innings), down from 8.3% the previous season.
