Left-hander Robert Gasser is emerging as a key player for the Milwaukee Brewers as they prepare for spring training. Acquired in the Josh Hader trade, Gasser has shown promise, particularly during his brief MLB stint in 2024, where he recorded a 2.57 ERA and minimal walks before undergoing Tommy John surgery. With two openings in the starting rotation, Gasser's left-handedness gives him an edge over other contenders, though he faces competition from Aaron Ashby and others. His performance in Nashville and potential in the upcoming season make him a player to watch closely.

By the Numbers
  • 3.79 ERA during 2023 season in Triple-A Nashville.
  • 3.38 FIP with a 2.57 ERA in five MLB starts in 2024.
  • 0.9% walk rate and 14% strikeout rate in those starts (1 walk, 16 strikeouts in 28 innings).
State of Play
  • Gasser is vying for the No. 4 or 5 spot in the Brewers' rotation.
  • Only left-handed option among primary rotation candidates, boosting his prospects.
  • Maintains three minor league options, securing potential future flexibility.
What's Next

With spring training approaching, Gasser's performance will be closely monitored as he aims to secure a starting role. His health and effectiveness during the preseason will influence whether he begins the season in the rotation or the bullpen. If other candidates perform unexpectedly well, Gasser may need to adapt quickly to a relief role.

Bottom Line

Robert Gasser's unique profile as a left-hander and his promising past performances position him as a frontrunner for a rotation spot, making him a player of significant interest for the Brewers in the 2026 season.
