The White Sox are expected to select Smith's contract from Triple-A Charlotte on Saturday, James Fegan of SoxMachine.com reports.
Smith turned in a 4.58 ERA and 1.37 WHIP in 57 innings across 15 starts before moving to the bullpen in July, and he has since given up just one run while fanning 10 batters over 6.1 frames. The 22-year-old will now get an opportunity to contribute for the big club during the final months of the season but is likely to remain in the bullpen to begin his MLB career.
