Wilson was optioned to Triple-A Gwinnett on Sunday, David O'Brien of The Athletic reports.
The 23-year-old recorded the win Saturday after giving up one run over 6.2 innings, but he'll head back to Triple-A since Atlanta has a pair of scheduled off days during the upcoming week. Wilson has a 2.13 ERA, 1.03 WHIP and 9:2 K:BB over two starts (12.2 innings) in May, and it's only a matter of time before he receives another chance in the majors this season.
