The Guardians recalled Allen from Triple-A Columbus to serve as the 27th man for Sunday's doubleheader against the Cubs, Tim Stebbins of MLB.com reports.
The left-hander failed to crack Cleveland's starting rotation to begin the season and has instead stayed stretched out at Columbus. Allen pitched well in his lone Triple-A start, allowing one run on four hits with five strikeouts and a walk across five innings. Slade Cecconi and Parker Messick are penciled in as the Guardians' starting pitchers for the twin bill, setting up Allen to potentially work as a long reliever.
