Not long after his release, he started working in Extreme Championship Wrestling. He took on the name "Tony Mamaluke", with the last name being a reference to the former tag team he managed in WCW, as well as a play on Philadelphia's famous Tony Luke's restaurant. He joined The Full Blooded Italians, which consisted of Little Guido and Big Sal E. Graziano. The reasoning for his alignment with this group was a combination of his previous gimmick in WCW being similar, as well as his resemblance to the character Christopher Moltisanti of the Italian-American mobster television series The Sopranos. As part of his gimmick, the ring announcer announced his weight in liquid ounces rather than pounds or kilograms, due to his unusually small stature. The two also began using the liquid ounce measurement as a reference to the size difference between the two smaller active wrestlers, and their large manager. His debut match was against Mikey Whipreck on ECW on TNN, in which Mamaluke took a couple hardcore bumps. Spencer was initially a member in training, until he became a full-fledged member when the tandem captured the World Tag Team Championship from The Unholy Alliance on August 25, 2000, on Day Two of Ballroom Blitz, which was ECW's debut at the Hammerstein Ballroom in New York. The two teams feuded for several months, with their respective managers, Big Sal and The Sinister Minister creating further conflict. They lost the title, however, on December 3, 2000 at Massacre On 34th Street to Danny Doring and Roadkill. During this time, he also feuded with Super Crazy and Kid Kash. He stayed with ECW until the company was declared bankrupt in April 2001.
