But Myers' arrival on Sunday in Detroit will only add to the setup excellence in front of closer Addison Reed, not supplant the rookie from his job.
"This is in no way a sign that anyone is wavering on Addison Reed and our confidence in him," White Sox general manager Ken Williams said after sending two Minor League pitchers to Houston for Myers. "Ultimately, the ninth inning is [manager Robin Ventura's] call."
After Saturday's 7-1 loss to the Tigers, marking a fourth straight setback for the White Sox and a drop into second place in the American League Central, Ventura made that call in favor of Reed.
"Reeder is still going to be closing," said Ventura of the bullpen alignment. "Right now, [Myers] is probably in there doing the same stuff as Jesse [Crain].
"There's the option to move him around and do a lot of different stuff. But for me right now, Addy has really earned the right to do that. He's going to be the one doing that."
Reed has 15 saves in 18 opportunities but is coming off of his toughest blown save of the year, which came on Thursday, when Red Sox outfielder Cody Ross launched a walk-off three-run shot at Fenway Park. The 23-year-old Reed has shown great resilience and fortitude in handling this job, through the ups and downs.
