will make his second start of the season for the D-backs in place of Taijuan Walker on Monday against the Pirates.
Walker is on the 10-day disabled list with a blister on his index finger and Delgado took his place last Wednesday against the White Sox. It was the right-hander's first start since 2015, and he allowed two runs (one earned) over four innings while throwing a season-high 61 pitches.
The D-backs ran through five relievers after Delgado, but they got seven innings Thursday from left-hander Robbie Ray, which gave the bullpen a chance to get back to nearly full strength.
