Oscar Delahoya is correct in his ringside belief that Mayweather lost the fight. You could see it in the faces of many of those ringside too who looked very worried that their bets were not going to come off as Maidana rallied in the final two having banked the first half of the fight. The spectacle of Mayweather looking flashy to the see the fight through fell away as Maidana rallied and worked and worked in the 11th and 12th. Look into those faces. They were delighted as Mayweather came on, but looked very distraught as Maidana showed his strength. This is the first convincing Mayweather defeat.
