The Yankees placed Caballero on the 10-day injured list Tuesday due to a right middle-finger fracture.
Caballero suffered the injury during Sunday's loss to the Brewers on a dive back into first base. It's unclear exactly how long the 29-year-old will be sidelined, but he'll be eligible to be reinstated from the IL on May 21. Anthony Volpe was called up from Triple-A Scranton/Wilkes-Barre in a corresponding move and is likely to step in as New York's primary shortstop.
