Five keys for Robert Guerrero

Interim welterweight titlist Robert "The Ghost" Guerrero (30-1-1, 18 KOs) will take on former titlist Andre Berto on Saturday (HBO, 10 p.m. ET/PT) at the Citizens Business Bank Arena in Ontario, California. The fight will be a true test for the Californian fighter in just his second welterweight fight after campaigning at lightweight for most of his career.

These are the keys to a possible Guerrero victory over Berto (28-1, 22 KOs) on Saturday:

The more, the better

Take and give

Prepare for a long battle

Fight, think, adjust, collect

Don't be brave, be smart
