He's tired of not getting a title shot. He didn't even get put into the world championship 1st contenders match the week before, despite having a winning streak and is pissed. So he costs Sheamus the match out of jealousy and beats him up badly. Then lets Alberto get the win. He hits Alberto with the World heavyweight championship though and beats him up too. He leaves the ring, and out comes Ziggler. Sheamus is slowly getting up and Ziggler hits Sheamus with the briefcase and throws Sheamus out the ring. Then cashes in and beats Alberto to become the new World Heavyweight championship.
