Dominik Mysterio captures AAA Mega Championship amid controversy

Dominik Mysterio captured the AAA Mega Championship in controversial fashion Friday night, pinning El Hijo del Vikingo in the main event of WWE x AAA Worlds Collide at the Cox Pavilion at the Thomas and Mack Center in Las Vegas. The victory, which made Mysterio a simultaneous holder of the AAA Mega and WWE Intercontinental titles, came after heavy interference and a disputed finish that left the arena raucous and many questions about the outcome.

The match, televised as part of the crossover special, saw members of Mysterio's Judgment Day faction, Finn Balor and JD McDonagh, repeatedly involve themselves, while Dragon Lee and Rey Mysterio ran out late to aid Vikingo. Video from the broadcast showed El Grande Americano also enter the fray, first pulling a referee out of the ring as Vikingo appeared poised to secure a pin. As Vikingo tried to remove Americano's mask, Americano is reported to have slid a metallic object into the ring and then into Mysterio's mask while the referee was distracted. Mysterio, with the object hidden in his mask, struck Vikingo and then landed a frog splash. A replacement official counted the pin, awarding Mysterio the championship.
