Amir Khan dominates in Vegas to beat Alexander

Amir Khan has beaten Devon Alexander by a unanimous points decision at the MGM Grand in Las Vegas.

Khan controlled the fight from the start, using his superior speed to stay ahead of Alexander and out-punching his American opponent who could do nothing to change the rhythm as the night went on.

Khan's performance was reflected in a comfortable win, with the fight scored 119-109, 118-110, 120-108 - the 30th win of his professional career.

Having taken care of business, Khan immediately signalled that he wanted to use the win to earn a shot at Floyd Mayweather.

Wearing his specially-designed shorts encrusted with 24-carat gold, Khan ruled the ring as he was able to have the final word in almost every round.

"We worked very hard for this fight," Khan said. "I knew I had to make a statement at the 147lbs division against a tough guy in Devon. I think it was one of my best performances because I wasn't rushing, I was on my feet, up against a very good fighter. I knew not to make any mistakes."

Khan admitted he had to temper his natural instincts in order to retain control, and believes it is a sign of his growing maturity.

"I feel better now at 28 than I did when I was 25. I'm hitting my peak now."

Khan added on Twitter that he wants to fight Mayweather on May 2.
