Diamondbacks' Ryne Nelson: Slated for bullpen session

Diamondbacks manager Torey Lovullo said Nelson (elbow) will throw a bullpen session Wednesday, Theo Mackie of The Arizona Republic reports.

Nelson went on the 15-day injured list last week after being struck on the pitching elbow by a comebacker. He appears to be making a quick recovery, and he could have a shot to return when first eligible for activation May 4 or shortly thereafter.
