Fans seven in tough loss
Junk (2-1) took the loss Wednesday as the Marlins were downed 2-1 by the Twins, giving up two runs on six hits over six innings. He struck out seven without walking a batter.
Analysis
The 29-year-old righty set a new season high in strikeouts en route to his first career quality start, but a Kyle Stowers solo shot in the second inning was all the offense Miami could muster for him. Junk has had a couple stumbles since joining the Marlins' staff in late May, but he's made a good case to stick in the rotation as either a traditional starter or bulk reliever, posting a 3.62 ERA, 1.13 WHIP and eye-popping 33:2 K:BB over 37.1 innings in eight appearances (three starts). He's scheduled to make his next trip to the mound on the road early next week in Cincinnati.

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.
