Due to repeated failures of ECW paying Corino his salary, he left the company on January 7, 2001, the night he lost the ECW World Heavyweight Championship to The Sandman at Guilty as Charged 2001. His friend Dustin Rhodes got him a contract in World Championship Wrestling, but he never got to make an appearance despite being due to debut at the company's third to last PPV Sin. When World Wrestling Entertainment took over WCW in March 2001, they released Corino from his contract. He went on to wrestle for many of the National Wrestling Alliance regional promotions. On April 24, he won the NWA World Heavyweight Championship.
