Clarke logged a hold with one perfect relief inning in Tuesday's 12-11 extra-innings win over the Angels.
Clarke worked the eighth inning without trouble, but the game got chaotic after that. The 29-year-old is up to four holds in 26 appearances this season, maintaining a mid-leverage role in the Royals' bullpen. He's added a save, two blown saves, a 4.88 ERA, 1.41 WHIP and 23:3 K:BB across 27.2 innings, but he's not expected to be in serious contention for regular save chances.
