Cantillo will be called up from Triple-A Columbus to serve as the 27th man for Monday's doubleheader against the Royals, Zack Meisel of The Athletic reports.
EDGE Analysis
The Guardians have yet to officially announce their pitching plans for the twin bill, but Cantillo and Logan Allen will both be called up from Triple-A and should start the two contests in some order. Cantillo was demoted to Triple-A Columbus on Thursday, but he can make a quick return to the majors because he's being designated as the 27th man. The 24-year-old has struggled in his first taste of the big leagues this year with an 8.47 ERA, 1.76 WHIP and 14:9 K:BB over 17 innings.
