Later on in the show, he won the "Tony Rumble Memorial Battle Royal", with the assistance of manager Johnny Fabulous, and went on to defeat Luis Ortiz and Slyck Wagner Brown in a Triple Threat match to win the heavyweight championship. Three months later, he also wrestled Larry Huntly in a losing bid to capture the vacant AWA North Atlantic Heavyweight Championship. On March 10, 2007, Beau Douglas defeated DellaGatta for the NWA New England Heavyweight title in Saugus, Massachusetts, ending his third reign as champion. Douglas had originally lost the title to Rumble six years earlier at the "NWA 52nd Anniversary Show" in Nashville, Tennessee. It was also announced at that event that the promotion would be withdrawing its membership with the National Wrestling Alliance and reverted to its original Century Wrestling Alliance name. In May 2007, DellaGatta was one of several American independent stars which participated in MainStream Wrestling Entertainment's 6th annual "Sea Side Slam Tour" which visited 10 cities in Newfoundland and Nova Scotia over a two-week period. One of the highlights of the tour was a Fatal Four Way match in Windsor between DellaGatta, Scott Savage, "The Bollywood Don" Harv Sihra, and "X-Ray" Kyle Kruze, which Kruze won; both Kruze's MSW Atlantic Canadian Championship and CWA Cruiserweight Championship was on the line. After NWA New England ceased operations, DellaGatta was brought into the Millennium Wrestling Federation where he aligned himself with Johnny Fabulous and The Uprising (Joey Mercury and MWF Tag Team Champions The Canadian Superstars - Dave Cole & J-Busta). At MWF's August 4 supercard "Soul Survivor IV" DellaGatta lost to Tiger Mulligan at the Good Time Emporium in Somerville, Massachusetts. He also was a regular on its weekly television show "MWF Ultra". Some highlights included matches against Slyck Wagner Brown (December 2007) and a tag team match pitting he and stablemate Jimmy Jact Ca$h against Beau Douglas and Al Snow (March 2008). In April 2008, he took on MWF original "Straight Edge" Brian Fury, who was making his return to the promotion after a four absence. At MWF's "Night of Champions" that summer, it was announced by MWF President Johnny Fabulous that the MWF Tag Team Championship would be defended by any two members of The Uprising since the Canadian Superstars had failed to appear to at the event.
