Atlanta recalled Hicklen from Triple-A Gwinnett on Saturday.
Since joining the 40-man roster in mid-June, Hicklen has slashed .259/.330/.506 with five homers, 20 RBI, 16 runs and four steals across 91 plate appearances. He'll now join the big club for the first time this season to replace the injured Mike Yastrzemski (elbow). Hicklen and Eli White will likely compete for starts in the outfield until Yastrzemski is healthy.
