Washington native Ronald "Winky" Wright, boxing's undisputed 154-pound champion, will fight Shane Mosley in a rematch Nov. 20 at Mandalay Bay Resort and Casino, promoters announced during a news conference yesterday in Las Vegas.

Wright (47-3, 25 knockouts), who grew up in Washington and lives in St. Petersburg, Fla., upset Mosley (39-3, 35 KOs) in a 12-round unanimous decision on March 13 to win Mosley's WBC and WBA 154-pound titles. Wright said yesterday that he hoped to fight Felix Trinidad or the winner of tonight's middleweight championship bout between Oscar De La Hoya and Bernard Hopkins, but he is contractually obligated to fight Mosley again.

Mosley "was the only one who stepped up and fought me," Wright said. "It's only fair for me to give him a rematch if that's what he wants. My goal is to beat Mosley again, first and foremost."

Mosley's stunning loss to Wright, who was a 3-to-1 underdog and was paid only $750,000 for the fight, was a costly one. Mosley could have fought De La Hoya for a third time, after beating him in 2000 and 2003, but he balked at a rematch because De La Hoya was going to get $15 million, while Mosley was only guaranteed $12 million. So Mosley took a $3 million payday to fight Wright, and the loss cost him a fight against Trinidad.
