After John Cena won his 17th World title at WrestleMania 41, it was only appropriate that Randy Orton stepped forward as his first challenger.

Cena and Orton came up through the WWE farm system at the same time more than 20 years ago, in a class that also included Dave Batista and Brock Lesnar.

Let’s look at the major battles between Cena and Orton over the years before they renew their rivalry this Saturday at Backlash.

2007

At SummerSlam, Cena retained the WWE title after hitting the Attitude Adjustment. The show took place in New Jersey, the site of this year’s first two-night SummerSlam.

Orton got a rematch at Unforgiven one month later. Cena got disqualified, so he didn’t lose the title.

This was supposed to lead to a Last Man Standing bout at No Mercy, but Cena had to vacate the title due to a torn pectoral muscle.

2008

Cena make a shocking early return from his injury and won the Royal Rumble. Instead of waiting for WrestleMania, he challenged Orton for the title at No Way Out.

Orton slapped referee Mike Chioda in the face to save his title on a disqualification. Cena got another title shot at WrestleMania, joining Triple H in a Triple Threat match. Orton pinned Cena to win the match.

2009

Orton was the champion going into SummerSlam, and he cheated to retain the title. By this time, both Orton and Cena were five-time champions.

Cena won the title at Breaking Point in Pittsburgh one month later. He survived a brutal kendo stick attack while handcuffed before rallying to victory.

Orton recaptured the title at Hell in a Cell 2009, winning the cage match after a running kick to the head.

Three weeks later, Cena recaptured the belt in an 60-minute, Anything Goes Iron Man match. After interference from Cody Rhodes, Ted DiBiase Jr., and Kofi Kingston, Cena won by a 6-5 score.

2013-2014

World champion Cena and WWE champion Orton unified the titles at the Tables, Ladders & Chairs pay-per-view in December 2013. Orton pulled Cena off the ladder and through a table to grab the belts.

Cena got a rematch at Royal Rumble, but Orton prevailed in that match as well.

Their other non-title match on pay-per-view was at Hell in a Cell 2014. Cena won the cage match to become the No. 1 contender to the WWE title.

All told, Cena leads the series with Orton by a 13-7-1 margin. Orton has a 5-4 advantage in championship matches.

So nobody is more qualified to dethrone John Cena than Randy Orton, especially in front of Orton’s hometown fans in St. Louis.
