Montas declined his portion of a $20 million mutual option for 2025, Adam McCalvy of MLB.com reports.
He'll receive a $2 million buyout instead. Montas, who will turn 32 in March, posted a 4.84 ERA and 148:66 K:BB across 150.2 frames covering 30 regular-season starts between the Reds and Brewers in 2024 and allowed three runs (one earned) over 3.2 innings in a postseason start for Milwaukee. He had 70 strikeouts in 57.1 innings after the Brewers acquired him and tinkered with his pitch mix.
