The Brewers recalled Sproat from Triple-A Nashville on Monday, Adam McCalvy of MLB.com reports.
He'll join the 28-man active roster as a replacement in the bullpen for Grant Anderson (biceps), who was placed on the 15-day injured list. Sproat has primarily operated as a starter between stops with Milwaukee and Nashville this season, but he made his most recent Triple-A appearance as a reliever. The 25-year-old has posted a 5.27 ERA, 1.42 WHIP and 100:48 K:BB over 95.2 innings with the big club in 2026.
