Tate Kuehner: Rising Brewers Prospect Poised for 2026 Impact

Milwaukee Brewers left-handed pitcher Tate Kuehner is quickly ascending through the organization’s minor league system, and could make an impact at the major league level in 2026. After a strong 2025 season and a non-roster invite to spring training, Kuehner is positioned as an under-the-radar arm to watch.

From Louisville to Nashville: Kuehner’s Rapid Ascent

Drafted by the Brewers in the seventh round of the 2023 MLB Draft out of the University of Louisville , Kuehner has demonstrated rapid progress. He spent 2024 with the Wisconsin Timber Rattlers and the Biloxi Shuckers, before earning a promotion to the Triple-A Nashville Sounds in August 2025 .

Kuehner made his Triple-A debut on Wednesday night, August 13, 2025, allowing just one run over 5 1/3 innings in a 2-1 loss to the Durham Bulls . He finished the game with one walk, four strikeouts, and scattered six hits, throwing 57 of 87 pitches for strikes.

2025 Performance and Strengths

Kuehner finished the 2025 season with a 2.77 ERA across 23 starts. His success stems from a deceptive delivery with a low arm slot, which proves particularly challenging for left-handed batters. In 2025, lefties managed just a .161 batting average and .504 OPS against him.

Kuehner’s pitching arsenal includes a four-seam fastball sitting in the mid-90s, complemented by a sweeping slider and a changeup. He also incorporates a cutter, a sinker, and a curveball, offering a diverse mix of pitches . While there’s potential for refinement, this pitch mix provides a solid foundation for success at the next level.

Looking Ahead to 2026

Despite not being featured on top 100 prospect lists, Kuehner is an intriguing arm with the potential to contribute to the Brewers in 2026. He was invited to spring training as a non-roster player, providing him an opportunity to showcase his skills to the MLB club .

Kuehner’s ability to effectively neutralize left-handed hitters could make him a valuable asset out of the bullpen, or potentially as a back-complete rotation piece, depending on his development throughout the 2026 season.
