Prior to tonight's game vs. Toronto, the Chicago White Sox announced the following three roster moves:
 
•   Recalled RHP Thyago Vieira from Class AAA Charlotte;
•   Purchased the contract of RHP Tyler Danish from Charlotte;
•   Designated RHP Chris Volstad for assignment.
 
Vieira, 25, went 0-4 with a 5.05 ERA (23 ER/41.0 IP), six saves and 50 strikeouts over 36 relief appearances with Charlotte this season. He averaged 11.0 strikeouts per 9.0 IP and limited righties to a .198 (17-86) average. Vieira was named to the 2018 International League midseason All Star team.
 
The 6-foot-2, 210-pound Vieira served as the 26th man for the second game of a doubleheader on June 22, but did not pitch. He made his major-league debut with Seattle on August 14, 2017 vs. Oakland, tossing 1.0 scoreless IP in his only career appearance. Vieira, who will wear uniform No. 50, was acquired by the White Sox from the Mariners in exchange for international signing bonus pool money on November 15, 2017.
 
Danish, 24, has gone 1-3 with a 3.06 ERA (22 ER/64.2 IP), 46 strikeouts and a .230 (55-230) opponents average over 29 games (two starts) with the Knights in 2018. He owned a 1.04 ERA (2 ER/17.1 IP) over seven outings in July.
 
The 6-foot, 220-pound Danish is 1-0 with a 2.70 ERA (2 ER/6.2 IP) and six strikeouts over four major-league games (one start) with the Sox from 2016-17. He will wear uniform No. 60.
 
Volstad, 31, went 1-5 with a 6.27 ERA (33 ER/47.1 IP) and 29 strikeouts in 33 appearances (one start) with the White Sox this season.
 
The White Sox 40-man remains at 38.
