Schultz was promoted to Double-A Birmingham on Sunday, James Fegan of SoxMachine.com reports.
Schultz has produced a 3.95 ERA and 0.91 WHIP with 42 strikeouts over 27.1 innings in seven starts with Single-A Winston-Salem so far this season, and he'll now move up another step in Chicago's farm system. The left-hander was selected in the first round of the 2022 MLB Draft by the White Sox, and he's considered one of the organization's top pitching prospects.
