Amir Khan defeated Dmitriy Salita in just 76 seconds to retain his World Boxing Association (WBA) light-welterweight title here at the Metro Radio Arena Saturday. The 22-year-old Briton ended the unbeaten record of New Yorker Salita after flooring the challenger twice before finishing the fight with a left hook to the chin to complete a speedy first title defense. WBA champion Khan has declared he wants to fight in America in 2010 and this victory once again showed how the 2004 Athens Olympic silver medallist is improving since losing his unbeaten record last year. Salita, born in Ukraine but who moved to New York in his childhood, claimed he would expose Khan's punch resistance, but there was no repeat of the bout in September last year when the Briton was blown away in just 54 seconds by Colombian Breidis Prescott. Instead, it was Salita who was overwhelmed in the first round. Williams earns decision Paul Williams showed why he's one of the most respected fighters in the world with a contentious majority decision over Argentina's Sergio Martinez in a non-title middleweight bout in Atlantic city Saturday. One of the judges, Pierre Benoist, scored the fight a whopping 119-110 in favor of the American, while Lynne Carter had it 115-113 for Williams. Julie Lederman scored the bout 114-114. It was Benoist's scorecard that upset Martinez's promoter, Lou DiBella.
