The White Sox announced a flurry of roster moves Tuesday, optioning right-hander Thyago Vieira and outfielder Charlie Tilson to Triple-A Charlotte and right-hander José Ruiz to Class A Winston-Salem.
The club also reassigned infielder Jake Burger, right-handers Dylan Covey and Michael Ynoa, catcher Alfredo González and left-hander Jordan Guerrero to Minor League camp.
Burger, Chicago's first-round selection in 2017, ruptured his left Achilles tendon on Feb. 26, and he is expected to miss the entire '18 season. He is ranked as the eighth-best prospect in Chicago's farm system.
