The Chicago White Sox acquired minor league right-hander Thyago Vieira from the Seattle Mariners in exchange for international signing bonus pool money, the teams announced Thursday.
Vieira also made one appearance with the Mariners last season, retiring all three batters faced in his major league debut versus the Baltimore Orioles on Aug. 14. The 24-year-old became the fifth native of Brazil to play in the majors, joining Yan Gomes, Andre Rienzo, Paulo Orlando and Luiz Gohara.
