Juan Carlos Oviedo will begin his rehab at the Marlins' spring training complex on Saturday. Oviedo will be eligible to return from his suspension on July 23 and will assume a setup role ahead of Heath Bell. Of course, with Bell's struggles, it's not out of the question that he could eventually garner some save chances. "He is throwing very well. He is very excited to get back,'' ‪Marlins‬ general manager Mike Hill said.
