"We're hoping he's over the hump," D-backs manager Kirk Gibson said. "If everything goes good, he'll hit live off Matt Reynolds on Friday."
Reynolds is rehabbing from Tommy John surgery.
• Outfielder A.J. Pollock (fractured hand) went 0-for-3 for Triple-A Reno on Friday night as he continued his rehab assignment.
"He's just trying to get his strength back in that hand," Gibson said. "He's got a lot of swelling in it, and he has to get that all out of there and get his strength in the hand back. That'll take some time."
