Battenfield's contract was selected from Triple-A Columbus on Friday.
Battenfield will join the Guardians for their weekend series in Toronto after James Karinchak (personal) was placed on the restricted list Friday. Battenfield hasn't yet made his major-league debut but has posted a 3.19 ERA and 1.20 WHIP in 121.1 innings over 21 starts in Columbus this year, although if he sees any action for Cleveland it will likely come out of the bullpen.
