White Sox general manager Rick Hahn wants to see more from Kopech at Triple-A Charlotte before elevating the right-hander to the major-league roster, Tom Musick of the Chicago Sun-Times reports.
Kopech appears to have fixed the command issues that bedeviled him for much of this season, posting 24 strikeouts against just two walks over his last three outings (17 innings). That includes Thursday's win, his first start all season without a walk. His numbers indicate that Kopech looks ready for a promotion, but Hahn stresses the organization has a longer checklist. "Not until they've answered all those questions we have for them at the minor-league level will we promote them," said Hahn, referring to both Kopech and outfielder Eloy Jimenez.
