Arroyo (elbow) is expected to throw a bullpen session Tuesday, Jack Magruder of FOX Sports Arizona reports.

Analysis:

Arroyo is at about the 10-month mark in his recovery from Tommy John surgery and shouldn't be expected to return to action until after the All-Star break. He'll require several bullpen sessions before the Diamondbacks entertain the idea of having him face hitters.
