2025 Fantasy Outlook
There was no outlook written for Janson Junk in 2025. Check out the latest news below for more on his current fantasy value.
$Signed a one-year, minor-league contract with the Marlins in February of 2025.
Moved to minors camp
PMiami Marlins  AAA
March 22, 2025
The Marlins reassigned Junk to minor-league camp Saturday.
ANALYSIS
Junk will finish Grapefruit League play with a 5.23 ERA and 1.06 WHIP alongside a 10:4 K:BB over 10.1 innings. He became a candidate to begin the season in Miami's rotation once Ryan Weathers went down with a forearm injury, but it now seems the Marlins will look elsewhere to fill their fifth rotation slot. Junk will presumably still be stretched out into a starter with Triple-A Jacksonville to provide extra organizational depth, though his fantasy appeal will be minimal if he finds his way back into the big leagues.

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.
The Angels acquired Junk from the Yankees in July of 2021 as part of the trade that sent Andrew Heaney to New York. Junk had an up-and-down initial taste of the majors, posting a 3.86 ERA and a 10:2 K:BB over 16.1 innings that season. He spent most of 2022 with Triple-A Salt Lake but had three scattered outings with the Angels. The right-hander looked good in his first start of the campaign, striking out eight batters in five scoreless innings but faltered in his next (and final) appearance, yielding six runs in 2.1 frames. Junk relies primarily on a fastball-slider combo -- the slider is the better offering, but the fastball is thrown with enough spin to be effective despite sitting in the low-to-mid-90s. He enjoyed a breakout campaign in 2021 at Double-A while in the Yankees system, posting a 1.78 ERA and 0.97 WHIP over 14 appearances. However, that performance looks like an outlier, as none of his his seasons before or since are on the same radar. That's not to say Junk won't be an effective big-leaguer, but he's not likely to evolve into a front-of-rotation starter. The Angels moved Junk to Milwaukee in November as part of a trade to acquire Hunter Renfroe. He's likely slated to start 2023 at Triple-A or in the big-league bullpen.

Latest Fantasy Rumors
Better odds to start?
PMilwaukee Brewers  AAA
February 8, 2023
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.
