Five keys for Marcos Maidana

— -- Argentine slugger Marcos Maidana was the driving force as Floyd Mayweather Jr. produced one of the most exciting fights of his career when the two met for the first time in May.

But despite pushing the pound-for-pound king to the limit in Mayweather's toughest fight in 12 years, Maidana (35-4, 31 KOs) was unable to pull off the upset despite coming so close. His performance, however, created enough demand for a rematch that Mayweather (46-0, 26 KOs) agreed to a second fight for just the second time in his career.

Maidana, 31, will get his shot at redemption when he faces Mayweather in Saturday's rematch at the MGM Grand Garden Arena in Las Vegas (Showtime PPV, 8 p.m. ET).

Does the exciting fighter have enough in the tank to hand Mayweather, 37, the first defeat of his career? It wouldn't hurt his chances if he considered these keys to victory:
