The Diamondbacks reinstated starting pitcher Chase Anderson from the 15-day disabled list on Friday, the team announced.
Anderson will rejoin the team's rotation during its weekend series against the Reds. He has been on the disabled list since July 19 because of a triceps injury.
In a corresponding move, Arizona optioned pitcher Allen Webster to Triple-A Reno. Webster, who was recalled on Wednesday, is 1-1 with a 6.86 ERA this season.
