The Brewers designated McCullers for assignment Sunday.
After being acquired from the Astros in mid-July, the veteran right-hander made two relief appearances for the Brewers and surrendered five runs (two earned) with a 5:5 K:BB across 4.2 innings. McCullers -- who has a 6.55 ERA and 1.55 WHIP through 10 big-league appearances in 2026 -- is likely to go unclaimed on waivers, given that Milwaukee still owes him $4.2 million for the rest of the season, per Spotrac.com.
