2025 Fantasy Outlook
The left-hander missed the entirety of the 2023 campaign while recovering from shoulder surgery, and he spent most of 2024 at Triple-A Nashville. Ashby started in 14 of his 25 appearances at Triple-A and struggled to an 8.04 ERA, 2.00 WHIP and 92:73 K:BB across 84 innings. He received a look in the majors despite the poor numbers and pitched well with a 2.86 ERA and 33:10 K:BB over 28.1 frames. The control difference between the majors and minors makes all of his numbers difficult to trust, but he should have a chance to earn a spot in Milwaukee's starting rotation in spring training. Ashby still has some upside but carries a lot of risk given the mostly unproven track record. Read Past Outlooks

Reinstated from IL
The Brewers reinstated Ashby (oblique) from the 15-day injured list Friday.
ANALYSIS
Ashby is set to make his 2025 MLB debut after beginning the season on the injured list due to a right oblique strain. During his five-outing rehab stint between the rookie-level Arizona Complex League and Triple-A Nashville, Ashby made all but one of his appearances out of the bullpen and didn't cover more than two innings in any of those games, so he looks set to fill a relief role for Milwaukee after having previously made 25 starts at the big-league level from 2021 through 2024.

Past Fantasy Outlooks
2024
2023
2022
Ashby began experiencing left shoulder discomfort in August of 2022, exactly four weeks after he signed a five-year, $20.5 million pre-arbitration contract extension with the Brewers. That shoulder issue began rearing its ugly head again in the spring of 2023, eventually leading to April 7 season-ending surgery. He was able to fit in a minor-league rehab assignment at the tail end of the 2023 campaign but surrendered 14 runs -- 12 earned -- on seven hits and 14 walks over seven innings (seven appearances) between High-A Wisconsin, Double-A Biloxi and Triple-A Nashville. Ashby is expected to be ready for the 2024 major-league season and still presumably possess a nasty slider-changeup combo to pair with his mid-90s fastball, but it'll take a lot of trust to reach for him in any sort of fantasy setting this spring.

Latest Fantasy Rumors

Joining MLB roster?
Ashby has yet to officially be added to the MLB roster but is with the team in Philadelphia and has a locker in the Brewers clubhouse, Todd Rosiak of the Milwaukee Journal Sentinel reports.
ANALYSIS
The left-hander is likely up with the Brewers as starting depth since Robert Gasser is dealing with an elbow issue. Ashby gave up four earned runs over 3.2 frames in his lone outing of the season for Milwaukee, and he has a 6.80 ERA over 43.2 innings at Triple-A Nashville. He struggled early on in 2024 in his return from shoulder surgery but has given up just two runs in his last two starts at Triple-A.
