The White Sox acquired Robertson from the Blue Jays on Wednesday in exchange for cash considerations, James Fegan of SoxMachine.com reports.
Toronto designated Robertson for assignment Sunday, but he'll reclaim a 40-man roster spot upon joining a new organization. The 27-year-old outfielder went just 1-for-10 at the plate during his three games in the majors with Toronto, but he's slashed an impressive .292/.403/.578 with 14 homers and 44 RBI over 233 plate appearances at Triple-A Buffalo. The White Sox will likely assign him to Triple-A Charlotte to begin his time in the organization.
