New York: Katie Taylor retained her lightweight world championship on Saturday, with a split-decision victory over Amanda Serrano on a historic night at the Madison Square Garden in front of a raucous sellout crowd.

The Irishwoman, who stretched her unbeaten professional record to 21-0, and Serrano were the first women to headline a fight at the world's most famous arena and put on a show-stopping performance equal to the occasion.

The Olympic gold medallist was left bloodied in the fifth round when Serrano decked her with a powerful overhand right and left hook but had a frenzied crowd on her side and battled through.
