Diamondbacks place Aaron Hill on DL; call up Didi Gregorius

The Arizona Diamondbacks have placed second baseman Aaron Hill on the disabled list with a broken left hand, according to Nick Piecoro of The Arizona Republic.

Arizona called up top shortstop prospect Didi Gregorius from Triple-A to replace Hill on the roster.

Hill suffered his injury last week when he was hit on the hand by a pitch. X-rays initially came back negative, and Hill went on to return for Arizona. He made two appearances as a pinch-hitter over the weekend, collecting an RBI double during one of his at-bats.

But it looks like Hill could have been playing through a broken hand, as new tests have revealed the injury. It's unclear if the second baseman's ailment was enhanced after his return to the lineup, and the D'backs have yet to announce an expected time frame for his recovery.

Gregorius was acquired from the Cincinnati Reds over the winter in the three-team trade that also included the Cleveland Indians. Prior to being called up by Arizona, the 23-year-old was off to a hot start in Triple-A, hitting .387/.424/.645 with two doubles and two home runs over 33 plate appearances.
