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
Clean inning in spring debut
Junk (ankle) struck out two batters and allowed one hit and no walks over a scoreless inning of relief in Saturday's 5-4 loss to the Astros in Grapefruit League play.
Analysis
Junk went down with a Grade 1 right ankle sprain early in camp, but after advancing through his throwing program over the last few weeks, he was finally cleared to make his spring debut Saturday. The 30-year-old right-hander made 16 of his 21 appearances with the Marlins last season as a starter, but the ankle issue may have cost him whatever small chance he had at a spot in Miami's Opening Day rotation. Junk should still be in good shape to break camp with the big club as a long man out of the bullpen.

Past Fantasy Outlooks
2024
2023
Acquired from the Angels in the Hunter Renfroe trade in November of 2022, Junk made just two appearances during his first year with the Brewers. The 28-year-old covered 140 innings at Triple-A Nashville last season and finished with an underwhelming 4.18 ERA, 1.35 WHIP and 94:44 K:BB. A move to the bullpen could be on tap for Junk in 2024 given his plus-4.00 ERA and subpar strikeout numbers (6.9 K/9) at Triple-A over the previous two seasons.

Latest Fantasy Rumors
Better odds to start?
Junk may have an improved chance of making the Brewers' starting rotation after Adam McCalvy of MLB.com reported Tuesday that Aaron Ashby will be behind to begin camp due to shoulder fatigue.
Analysis
Ashby missed time with shoulder inflammation last season, so the team may exercise additional caution this time around. Junk was acquired from the Angels in November and may have a hard time cracking the rotation, even if Ashby is unavailable for Opening Day. Junk has just seven big-league appearances under his belt and has a 4.74 ERA over 24.2 frames.
