Prior to tonight's game at Class AA Birmingham, the Chicago White Sox outrighted right-handed pitcher Javy Guerra to Class AAA Charlotte.
Guerra, 28, was claimed off waivers by the White Sox on Wednesday from the Los Angeles Dodgers.
The right-hander spent most of the 2013 season with Class AAA Albuquerque, appearing in 27 games (four starts). He also made nine appearances with the Dodgers.
Guerra has gone 4-5 with a 2.90 ERA (33 ER/102.1 IP), 87 strikeouts and 29 saves over parts of three major-league seasons with the Dodgers (2011-13). His best season came as a rookie in 2011 when he posted a 2.31 ERA (12 ER/46.2 IP), with a team-high 21 saves and 38 strikeouts in 47 appearances. Guerra followed with a 2.60 ERA (13 ER/45.0 IP) and eight saves in 2012.
Guerra will report to Chicago's spring training facility in Glendale, Ariz. today and join the Charlotte roster.
With the move, the White Sox 40-man roster is at 39.
