Alberto Del Rio arrived in grand style by driving into the Rabobank Arena in a Rolls Royce. And as he approached the ring, he was introduced by his very own personal ring announcer. Leading up to the big night, Del Rio touted himself in a series of videos (WATCH).

When all the hype and talking were over, and Del Rio finally stepped in the ring, he backed up his words with a huge win over veteran Rey Mysterio by making him tap out with a cross armbreaker. Adding insult to injury, Del Rio locked Rey in the same hold after the match was over to deliver more punishment.
