Clarke allowed two runs on one hit and one walk over a third of an inning in Monday's 6-5 loss to the Pirates.
The Diamondbacks held a 5-2 lead when Clarke entered to start the seventh inning, before the game was knotted at five by the time he and Joe Mantiply finished the inning. The 28-year-old former starter had been a reliable reliever until a shoulder injury shut him down in June. At the time, he had a 3.74 ERA, including a 2.37 stretch from May 1 to June 14. He's been less effective since his return earlier this month, giving up seven runs over eight appearances (9.45 ERA). It's a small sample, which can be attributed to the injury, but with spots in the 2022 bullpen wide open, the Diamondbacks would like to see the earlier version of Clarke cement a spot on next season's roster.
