The deal, which the club has not confirmed, is for $719,100 -- full-slot value for the 86th pick, where the Sox selected Call out of Ball State.
Call, a 5-foot-11, 185-pound outfielder, hit .358 with 13 home runs and 44 RBIs while also going 17-for 21 stealing bases this season. The right-handed hitter posted a .425 on-base percentage in three seasons at Ball State, including a career-best .443 in 2016.
"Just a terrific kid. Outstanding makeup. Just a gamer," White Sox director of amateur scouting Nick Hostetler said after the selection. "Played in a very good outfield in the Cape Cod [League] with Kyle Lewis and Ronnie Dawson as well. He's battle-tested. He draws walks, gets on base. He's going to be an asset for us."
