The Guardians returned Gillispie to Triple-A Columbus on Thursday.
Gillespie was sent back to Columbus after he served as the 27th man for Wednesday's doubleheader with the Diamondbacks, only to go unused in both ends of the twin bill. The Guardians have another doubleheader on tap Friday versus the Twins, but Joey Cantillo was called up from Triple-A to serve as the 27th man this time around.
