Pollock started his rehab stint with the Rookie League AZL Diamondbacks on Thursday at Salt River Fields at Talking Stick in Scottsdale, Ariz., and recorded one official at-bat before he left the game after the hit by pitch.
"It's OK, but it's swelling up a little bit," manager Kirk Gibson said. "I think he's going to take batting practice to see if he's going to play … tonight."
Gibson said he wasn't sure if Pollock was wearing any kind of protective glove while he hit, but he did say that if Pollock's latest hit by pitch didn't set him back, he could return to the D-backs in about two weeks.
Pollock had surgery on the hand in early June and has been on the 15-day disabled list since June 1.
Pollock's return could provide as big of a boost to the D-backs' lineup as a midseason acquisition. Before suffering the injury, Pollock had hit .379 in his previous 23 games with a 1.098 on-base-plus-slugging percentage. Despite missing two months, Pollock is still second on the D-backs in wins above replacement (WAR) at 2.7, behind only Paul Goldschmidt's 4.1 mark.
