Diamondbacks manager Torey Lovullo said that Ryne Nelson (elbow) will “most likely return in a bullpen role.”

Nelson is going to pitch in a rehab game in Visalia on Saturday, but he has been shut down since June 19th, so it’s unlikely he will be fully built up to a starter’s workload over the next few weeks. He has experience out of the bullpen and could be an asset for the Diamondbacks there as they fight for a playoff spot.
