Kranick will be promoted from Triple-A Indianapolis to start Wednesday against the White Sox, Kevin Gorman of TribLive.com reports.
Kranick has been in the minors since being demoted in early August, but he'll rejoin the big-league rotation Wednesday. The right-hander surrendered three earned runs over 4.1 innings during his last start for Indianapolis and has a 7.20 ERA over 20 big-league innings (five starts) this season.
