#4. AJ Styles enters elite grand slam territory at WrestleMania 37

AJ Styles may not have been in a "significant" match at WrestleMania 37, but his achievement puts him in elite territory. He is the 15th modern-day Grand Slam Champion in the newer format, and he achieved it in just a little over five years.
However, it wasn't AJ Styles who was the big talk of the match. It was his bodyguard Omos - who made his WWE debut at WrestleMania 37. It's a high-pressure situation to be in, but Omos overcame that and delivered in his debut - proving to be a good "big man".
He was the one who dominated Kofi Kingston and Xavier Woods singlehandedly - getting the pinfall with a single foot. While that may have added an insult to injury for The New Day, it was a great WrestleMania moment.
The match itself wasn't too technical, and it played out in an entertaining way. They say that WrestleMania is where stars are born, and Omos was one such star this year.
