The White Sox have added veteran lefty Ross Detwiler on a minor-league arrangement. The transaction was announced by the indy ball York Revolution, the club that Detwiler opened the season with.

Detwiler, 33, had turned in three solid starts in Atlantic League action to earn his way back into the affiliated ranks. The former sixth overall draft pick has thrown in parts of ten MLB campaigns.

If he’s to make it back to the bigs, Detwiler will need to earn his way onto the Chicago roster with a good showing at Triple-A. He hasn’t spent substantial time in the majors since 2016, with only one start logged since that time.

Over 584 career innings, Detwiler owns a 4.36 ERA with 5.5 K/9 against 3.3 BB/9. Though he never reached the ceiling suggested by his draft position, he had his moments with the Nats. From 2011-13, Detwiler threw 301 2/3 innings of 3.46 ERA ball while working mostly as a starter.
