What happened: Joel Kuhnel made a viral debut for the Milwaukee Brewers on June 8, hitting a 5 mph against his former team in Las Vegas. The appearance came just two days after Milwaukee activated Kuhnel following his acquisition from Oakland for cash considerations. Kuhnel's sinker averaged 98.8 mph in the outing, a staggering increase from the 94.1 mph average he posted earlier this season.
Why it matters: The sudden 'five-tick' jump in velocity suggests the Brewers' pitching lab has already unlocked significant mechanical gains for the veteran reliever. While Kuhnel allowed a home run in the 15-14 marathon win, his new ceiling changes his outlook in a Milwaukee bullpen known for maximizing reclamation projects. The move adds vital depth to the staff as they navigate the 2026 regular season.
By the numbers: Kuhnel's sinker topped 100.5 mph and averaged 98.8 mph, up from a 96.7 mph max and 94.1 mph average with Oakland. The June 9 finale of the Vegas series saw 29 total runs and 11 home runs between the Brewers and Athletics.
What to watch: Kuhnel will look to maintain this power as Milwaukee integrates him into higher-leverage relief situations. Scouts will monitor his next appearance to confirm if the velocity gains are sustainable.
