2026 Fantasy Outlook

Heading into last season, Junk had logged just 40 major league innings across four partial seasons, producing a 6.75 ERA with a 1.14 WHIP. In late May, Miami called him up from Triple-A Jacksonville to help stabilize an injury-ravaged pitching staff. He began in long-relief, then served as a primary pitcher, before joining Marlins' rotation. The result was a breakout campaign, though it included a brief injured-list stint due to right ulnar nerve irritation. His ERA matched its estimators, but repeating a 2.9 percent walk rate and 0.65 HR/9 will be difficult. That said, his 63.7 percent left on base rate was notably low, suggesting some bad luck. Even with increases in walks and homers, a normalized LOB mark could keep his ERA in check. Still, more walks would inflate his WHIP, and a below-average strikeout rate creates added risk. Junk should be given a chance to make the rotation but be ready to move on if things aren't going his way. Read Past Outlooks
