After blowing a save Sunday against the Tigers, Dominguez was quickly handed another opportunity Monday and came up short once again. Entrusted with a one-run lead in the ninth inning, the right-hander allowed a walk, a single and a double before recording an out, squandering the lead in the process. After striking out Rhys Hoskins for the first out of the frame, Dominguez was lifted, and one of his inherited runners came around to score. However, the White Sox offense answered with a walk-off win in the bottom of the inning. The 31-year-old's grip on the closer role appears tenuous, as he owns a 4.45 ERA, 1.34 WHIP and 33:16 K:BB while converting 12 of 17 save opportunities across 28.1 innings this season.

Dominguez was called upon to protect a three-run lead in the ninth inning and ultimately got the job done despite some late drama. The right-hander worked around two walks and an RBI double before recording the final outs to secure his 12th save of the season. It was Dominguez's first save since May 25, after posting five scoreless appearances and allowing just two baserunners total since. He now owns a 3.81 ERA, 1.19 WHIP and 31:15 K:BB across 26 innings this year.
