Cleveland added the 23-year-old Karinchak to the roster Friday before opening a three-game set against AL Central-leading Minnesota. The Twins lead the Indians by 3 ½ games.
Karinchak gives manager Terry Francona another late-inning option. Hand was sent back to Cleveland for an MRI on Thursday.
The left-hander has struggled for more than a month, with four of his five blown saves coming since July 12 along with a 5.68 ERA in the second half.
Karnichak is viewed as Cleveland’s future closer. The right-hander went 1-1 with eight saves and 2.67 ERA across the minors. He recently pitched 3 1/3 scoreless in three postseason appearances for Triple-A Columbus.
The Indians also recalled outfielder Bradley Zimmer, who has been rehabbing his surgically repaired right shoulder and other injuries.
