Boxer Amir Khan defeated Devon Alexander by a unanimous decision in a fight on Saturday, using his superior hand speed and strength to dominate for 12 rounds in a row. Scorecard of all three judges was: 120-108, 119-109 and 118-110.n“I think it was one of my best performances,” said Khan, who looked unscathed except for a welt under his left eye. “I am the best boxer with the quickest hands in the world. I am getting better.” Amir Khan has now won 30 of his 33 professional contests so far. We wish him all the luck and best wished for all his future matches!
