- Fantasy baseball: Reactions to MLB trade deadline deals
Track the fantasy fallout from all the key deals that went down before Monday's MLB trade deadline.
ESPN · Aug 4
The White Sox traded Dominguez, Nolan Jones and Boston Smith to the Mariners on Saturday in exchange for Luis Castillo, Jeff Passan of ESPN.com reports.
Dominguez opened the season as the closer for the White Sox but lost his grip on the job in late June. He'll now head to Seattle, where he'll presumably operate in a middle relief for the Mariners with Andres Munoz locked in as the closer. Dominguez has a 4.10 ERA, 1.37 WHIP, 12 saves (in 17 chances), four holds and a 45:23 K:BB over 37.1 innings this season.

Dominguez blew the save in Monday's 6-5 win over the Guardians. He allowed two runs on two hits and a walk while striking out one over one-third of an inning.
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 earned the save in Sunday's 6-4 win against the Dodgers, allowing one run on one hit and two walks while striking out two over one inning.
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.

Dominguez struck out one in a perfect eighth inning Saturday to record his first hold of the season in a 7-1 win over the Tigers.
After being used in the top of the ninth inning of a tie game Friday, Dominguez was brought back Saturday with the White Sox up 4-1 and Detroit's 2-3-4 hitters coming to the plate. The right-hander got the job done on 15 pitches (eight strikes), and the White Sox then added some insurance runs to erase the potential save chance in the ninth. Dominguez has produced four straight scoreless appearances, and on the season he sports a 3.97 ERA, 1.15 WHIP and 28:11 K:BB through 22.2 innings while converting 11 of 14 save opportunities.
RotoWire via ESPN · May 30
Dominguez earned the save in Monday's 3-1 win over the Twins, allowing one hit and no walks with two strikeouts in a scoreless ninth inning.
It was Dominguez's first save in 12 days and his 11th of the season. After allowing five runs in a combined two innings of work May 13 and May 17, Dominguez didn't pitch for a week. He's now posted back-to-back scoreless outings after the reset. The right-hander owns a 4.35 ERA and 26:11 K:BB across 20.2 innings this season.
