On March 14, 2004, at WrestleMania XX, Benoit won the World Heavyweight Championship by forcing Triple H to tap out to his signature submission move, the Crippler Crossface, in a highly acclaimed match. The match marked the first time the main event of a WrestleMania ended in submission. After the match, Benoit celebrated his win with then-reigning WWE Champion Eddie Guerrero. The rematch was held at Backlash in Benoit's hometown of Edmonton. It was Michaels who ended up submitting to Benoit's Sharpshooter, allowing Benoit to retain his title. The next night in Calgary, he and Edge won the World Tag Team Championship from Batista and Ric Flair, making Benoit a double champion.
