ATLANTA — The Braves declined their part of Billy Hamilton’s mutual option for 2020, allowing the speedy outfielder to become a free agent.

Hamilton’s contract, agreed to with Kansas City last December, called for a $4.25 million salary for this year and included a $7.5 million mutual option for 2020 with a $1 million buyout.

Hamilton, 29, hit .218 with no homers,15 RBIs and 22 stolen bases in 119 games for the Royals and Braves, who claimed him off waivers on Aug. 19.
