Schrock was diagnosed with a strained left calf after exiting Sunday's Cactus League game against the Diamondbacks, Bobby Nightengale of The Cincinnati Enquirer reports.

EDGE Analysis

Schrock was poised to open the season in a utility role for the Reds, but his availability for Thursday's season opener in Atlanta is now up in the air. The 27-year-old also spent a month on the shelf with a left calf strain last year, though it's unclear how much time he's expected to miss this time around.
