Rest-of-Season Projections

Rough outing in San Francisco
Junk allowed five runs on eight hits and struck out one without walking a batter over 3.2 innings in a no-decision Thursday versus the Giants.
ANALYSIS
Junk avoided walking a batter, but that was about the only positive to take from this unusually high-scoring contest at Oracle Park. He hasn't issued a walk in any of his last three outings, allowing six runs over 14.1 innings while adding 10 strikeouts. Junk won those previous two appearances and looks poised to have first dibs on the rotation spot that opened up when Max Meyer (hip) was ruled out for the season. Junk is at a 3.73 ERA, 1.15 WHIP and 26:2 K:BB across 31.1 innings over seven appearances this year. The 29-year-old is projected to make his next start at home versus the Twins.

Strikeouts may be lower than usual, but there are still a number of pitchers more than capable of doing well this week.

Ryan Pohle takes a deeper look into team stacks and pitchers for Friday's MLB slate, including Houston's Hunter Brown in a favorable matchup against the Angels.
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.
