Five keys for Andre Berto

A former WBC welterweight champion, Andre Berto (28-1, 22 KOs) has a chance for redemption Saturday (HBO, 10 p.m. ET/PT) when he faces WBC interim 147-pound champion Robert "The Ghost" Guerrero in Ontario, Calif.

Berto was suspended after testing positive for a banned substance before his scheduled June rematch against Victor Ortiz. That fight was later canceled.
