John Antonoff/For the Sun-Times In one of his first declarations under his new title of White Sox assistant general manager/player development, Chris Getz gave a strong indication that prospect Andrew Vaughn will be ready to handle designated hitter duty as soon as the first month of the season. Getz, the White Sox’ director of player development the last four seasons, was promoted to his new title when coaching and staff assignments throughout the farm system were announced Wednesday. Vaughn is the Sox’ top-rated prospect and is ranked No. 14 in baseball by MLB Pipeline. “I would imagine that [with] the amount of success he’s had and probably will have in spring training, that he’ll be in position to be that DH or be on the major-league club,” Getz said. “I would certainly share . . . that he is ready to help this team.”
