MILWAUKEE — The Milwaukee Brewers have declined to exercise a $15 million mutual 2021 option on veteran outfielder Ryan Braun as the franchise’s career home run leader ponders whether to continue playing.

Braun is due a $4 million buyout and became a free agent.

The 37-year-old often said this year that this might be his final season. He has spent his entire career in Milwaukee and has a franchise-record 352 career home runs.

Braun batted a career-low .233 with seven homers and 27 RBIs this year.
