Maxwell underwent Tommy John surgery in July and won't return this season, Susan Slusser of the San Francisco Chronicle reports.

Maxwell had been out of the lineup for Double-A Richmond since late June, but he only got the surgery about a week and a half ago. He ends 2021 with a .211/.319/.351 slash line, two home runs, 12 RBI and seven runs scored in just 18 games between Richmond and Triple-A Syracuse when he was in the Mets' organization. The catcher hopes to continue his playing career, but at 30 years old, a return to the majors isn't that likely.
