After being trained at Deep South Wrestling and Ohio Valley Wrestling, The Miz was promoted to the main roster in 2006. Within WWE, The Miz has won eighteen total championships: the WWE Championship once, the Intercontinental Championship eight times, the United States Championship twice, and seven tag team championships (two World Tag Team, four WWE (now Raw) Tag Team, and one SmackDown Tag Team), making him the 25th Triple Crown Champion and 14th Grand Slam Champion in company history.
The Miz also won the 2010 Money in the Bank ladder match (for Raw), and was ranked number one on Pro Wrestling Illustrated (PWI)'s annual PWI 500 list for 2011. He is one of the 10 most prolific pay-per-view performers in WWE history.
The Miz has headlined several pay-per-view events for WWE, including the 2011 edition of WWE's flagship event WrestleMania. Miz would begin to pursue a partnership with McMahon, with the promise of becoming the "best tag team in the world"
McMahon would finally agree to the team proposal in December, turning Miz into a fan favorite for the first time since April 2014. The duo would then challenge SmackDown Tag Team Champions Cesaro and Sheamus to a title match at the 2019 Royal Rumble pay-per-view on January 27, 2019, in which Miz and McMahon would defeat the duo to become the new champions.
However, the next month at Elimination Chamber, Miz and McMahon lost the titles to The Usos, ending their reign at 21 days. The duo then failed to regain the titles from the Usos at Fastlane in March. In a recent interview with Sports Illustrated, The Miz spoke about his feud with Shane McMahon: “My story with Shane isn’t finished.
Any time Shane McMahon is on a show, I’m going to come after him. When I get at him, it’s only going to take a split-second to demolish him. There will be a conclusion, a time when I get my hands on him where it will be the last period in any sentence”.
