WWE had an opportunity to create a new star a couple weeks ago when Kalisto surprisingly won the United States Championship on Raw. Not many would expect someone who is in a mid-card tag team to suddenly receive a title shot and actually win. So when Kalisto emerged victorious, it was a huge deal. But then the WWE creative team pulled its favorite gimmick, 50/50 booking. Alberto Del Rio immediately challenged for his title on Smackdown and won the U.S. title back, ending Kalistos reign at three days (or one day, if you look at when Smackdown was taped). This then set up the creative teams other favorite tool: the rubber match.Conceivably, the U.S. title could swap hands yet again on Sunday. The question is, can Kalisto pull it off? Del Rio winning effectively puts a fork in Kalistos singles push (at least for now), whereas Kalisto winning could help spark some credibility for the masked luchador in one-on-one competition. Which way will it go?
