The Cubs are expected to call up Thompson from Triple-A Iowa to start Saturday's game against the Royals, Russell Dorsey of the Chicago Sun-Times reports.
Though he has worked out of the bullpen in all but one of his 27 appearances with the Cubs this season, Thompson has been pitching exclusively as a starter since being optioned to Iowa in late July. He built up to 62 pitches in his most recent start for Iowa on Sunday, spinning 4.1 no-hit innings while striking out seven. Expect the Cubs to cap Thompson around 70-to-80 pitches in Saturday's start, assuming he does in fact get the call back to the big leagues. So long as Thompson doesn't completely implode in that outing, he could have a spot in the Chicago rotation for the rest of the season as the rebuilding club auditions the 26-year-old for a full-time starting role in 2022.
