The White Sox will add a major reinforcement to their pitching staff when they open a home-stand Monday, as Carlos Rodon will join the big league roster.

A major league source confirmed Sunday that Rodon will join the White Sox for the first time and will begin his tenure with the club pitching out of the bullpen.

Rodon, the top pitching prospect in the White Sox system, is headed for the rotation in the long term, but will get his feet wet by pitching in relief.
