The Royals designated Hamilton for assignment on Aug. 16 after he hit .211/.275/.269 with 18 stolen bases in 93 games in 2019. Kansas City signed the 28-year-old to a one-year, $5.25-million contract with a mutual option for the 2020 campaign during the offseason.
Though he's struggled to get on base with a lifetime OBP of .296, Hamilton amassed 50-plus stolen bases four times in six seasons with the Cincinnati Reds. His speed has also helped him become a five-time Gold Glove finalist.
Atlanta has recently seen its outfield hit by the injury bug: Nick Markakis is out with a fractured wrist and Ender Inciarte is dealing with a strained hamstring, leaving the Braves with an outfield alignment featuring Ronald Acuna Jr., Adam Duvall, and Matt Joyce.
In a corresponding move, the Braves optioned right-hander Bryse Wilson to Triple-A Gwinnett.
