Didi Gregorius (elbow) will make his Cactus League debut Thursday.
Gregorius will be limited to DH duty for now as he works his way back from a slight ulnar collateral ligament strain. "It's going great," D'backs manager Kirk Gibson said of Gregorius' progress. "At the same time, we're going to stay on the program. It's the right thing to do. He's exactly on schedule. He's had no setbacks along the way." Gregorius is slated to open the year as Triple-A Reno's shortstop.
