Clarke allowed three runs on three hits and failed to procure an out in the ninth inning of Thursday's 5-4 extra-inning loss to the Giants.
Clarke was reinstated off the 10-day injured list earlier in the day and summoned to protect a 4-0 lead in the ninth inning but could not. He allowed a double, a single and another double before being replaced by closer Tyler Clippard. From there, things went further south. The collapse was emblematic of this year's edition of the Diamondbacks' bullpen, which has an MLB-worst 5.43 ERA.
