Wilson was recalled from the Braves' alternate training site Sunday.
He will take the roster spot of Chad Sobotka, who was sent down following Saturday's game. This marks Wilson's second stint with the big-league team this year; he gave up two runs and walked four over 1.2 innings in his lone appearance back on Aug. 11. There's still some hope for Wilson as a starter long term, but he will likely work out of the bullpen again this time around, pitching mostly unimportant innings.
