Matthew Mueller gives Milwaukee a strike-throwing lefty with bat-missing upside
In the 2025 season, Milwaukee left-hander Matthew Mueller logged 41 1/3 innings over 16 appearances, posted a 5.23 ERA, struck out 55, and limited hitters to a .233 average, with standout flashes like 6 strikeouts in 3 2/3 innings at Mercer and 5 strikeouts in 2 hitless innings against Oakland. He looks like a high-effort, attack-minded arm who can work as both starter and leverage reliever; the swing-and-miss stuff is real, even if command and consistency still need polish. If your team wants a competitive lefty with upside and bullpen flexibility, he’s worth a serious look.
