The White Sox will likely use Erick Fedde and José Urquidy as bulk guys on Tuesday and Wednesday, respectively.

With Davis Martin on the IL and Noah Schultz back in the minors, the White Sox currently have just three true rotation guys in Sean Burke, Luis Castillo and Anthony Kay. After Castillo starts Monday, they’ll rely heavily on the pen in the final two games of their series against the Cubs. With Thursday off, they could then perhaps split up their bulk-guy days next time through the rotation.
