Robertson has returned to the White Sox's training camp from the World Baseball Classic and is uncertain when he'll next pitch for Chicago, Dan Hayes of CSN Chicago reports.

EDGE Analysis

Robertson last pitched in the final game of the WBC, mopping up Team USA's 8-0 championship win over Puerto Rico. He's already had plenty of work, much of it in the playoff-like atmosphere that is the WBC, so finding opportunities for him over the final week of training camp isn't paramount. Robertson will open the regular season as Chicago's closer, though he's in the same boat as other veterans on the roster of this rebuilding team. His name came up in trade talks all offseason, and he's expected to be dealt at some point.
