Wilson was optioned to Triple-A Gwinnett on Thursday.
Wilson earned the win Wednesday with two runs allowed over six innings, but he returns to Triple-A as the Braves bolster their bullpen depth ahead of the All-Star break. The 21-year-old is expected to return to the majors when the Braves first need a fifth starter after the break, lining up to pitch July 16 against the Brewers, Gabe Burns of The Atlanta Journal-Constitution reports.
