The Guardians selected Tolentino's contract from Triple-A Columbus on Friday, Tim Stebbins of MLB.com reports.
Tolentino will grab a spot on Cleveland's 40-man roster after slashing .225/.328/.453 with 21 homers, 74 RBI, 71 runs scored and 18 steals across 496 plate appearances at Triple-A Columbus this season. The 24-year-old shortstop will be protected from the Rule 5 Draft now that he owns a 40-man spot, and he'll have an opportunity to compete for an Opening Day roster spot in the spring.
