Swagger cashed in his Money in the Bank contract during the "SmackDown" taping on March 30, 2010, after the World Heavyweight Champion Chris Jericho had been speared by Edge. Swagger went on to defeat Jericho to win the World Heavyweight Championship for the first time. after his championship win, Swagger changed into a more serious Swagger which was different from his last persona, where he was known for doing pushups and beating his chest during his ring entrance. He defended his championship against Edge and Jericho in a triple threat match on the April 16 episode of "SmackDown", and against Randy Orton in an Extreme Rules match at the Extreme Rules pay-per-view. At Over the Limit, Swagger kept the title against The Big Show by disqualifying himself. At the Fatal 4-Way pay-per-view on June 20, he lost the championship to Rey Mysterio in a fatal four-way match, which also had CM Punk and The Big Show.
