The Brewers declined their side of Sanchez's mutual option for 2027 on Monday, Adam McCalvy of MLB.com reports.
Sanchez had a nice season as the Brewers' No. 2 catcher, posting a .771 OPS with 12 home runs. It's unlikely the soon-to-be 34-year-old will be entrusted with a starting job anywhere, but Sanchez should draw interest as a second catcher and occasional designated hitter.
