Rest-of-Season Projections

Bails out bullpen Friday
Junk gave up three hits and struck out five over four scoreless relief innings in Friday's loss to the Giants.
ANALYSIS
After Cal Quantrill provided the Marlins with five good innings, Junk finished up the 2-0 loss and gave the rest of the bullpen a much-needed night off. The 29-year-old righty has made two appearances for Miami since being called up May 24, allowing just one run over nine innings with a 9:1 K:BB. While the team doesn't have an opening in its rotation right now and should get Eury Perez (elbow) back in early June, Junk is making a case for an audition as a starter at some point down the road.

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.
