William Matthew Sierra is an American former professional wrestling referee and manager better known by his ring name Bill Alfonso. He achieved his greatest success in Extreme Championship Wrestling in the mid-to-late 1990s. He is well known for the whistle that was almost always hanging around his neck, which he blew constantly during his wrestlers' matches In May 1995, he made his debut in Extreme Championship Wrestling as a "trouble-shooting referee".Introduced by Shane Douglas, he angered many ECW fans with strict enforcement of the rules and disqualifications of wrestlers for such ECW traditions as using steel chairs as weapons.n this role, he engaged in a feud with ECW founder Tod Gordon that resulted in several wrestling matches.
Since the closing of ECW, Alfonso has appeared in several independent promotions. He worked one match in Xtreme Pro Wrestling as a referee. He has also worked in Elite Wrestling Entertainment as a referee and a manager,as well as managing wrestlers in Squared Circle Wrestling and Pro Wrestling Unplugged.In May 2007, he made his first appearance with Women's Extreme Wrestling, where he serves as a manager and as commissioner.
