Mantiply allowed one run on one hit and struck out one over two-thirds of an inning in Monday's 6-5 loss to Pittsburgh.
The Diamondbacks had a 5-2 lead entering the seventh inning, but the combination of Taylor Clarke and Mantiply let the Pirates tie it up. Mantiply made his first appearance since Aug. 12 after spending time on the COVID-19 injury list. He, like several others in the bullpen, is pitching for a spot on next season's roster.
