Ray (oblique) will be activated from the 10-day disabled list and start Wednesday's game against the Marlins, Zach Buchanan of The Athletic Arizona reports.
Ray was scheduled to make a third rehab start Monday, but the Diamondbacks evidently decided he was ready to return a little earlier than anticipated. The decision may have been made partly out of necessity, as Clay Buchholz hit the disabled list with an oblique injury of his own and the team needed someone to take his spot in the rotation. Ray threw just 66 pitches in his most recent rehab start, so there's a good chance he'll face some restrictions Wednesday as he takes the hill for Arizona for the first time since April 29.
