WBC heavyweight champion Deontay Wilder had backed Andy Ruiz to repeat on Saturday night in Saudi Arabia.

That didn't happen, with Anthony Joshua outboxing Ruiz over twelve rounds to reclaim the WBO, IBF, IBO, WBA world heavyweight titles.

Back in June, Ruiz dropped Joshua four times to secure a seventh round stoppage in a huge shocker.

Wilder, and most experts, did not expect Ruiz to enter the ring out of shape - 15 pounds heavier than he was in the first bout - and Ruiz was not exactly in top shape the first time around.

Joshua simply used movement and boxing, round after round, and also grabbed Ruiz when he came inside.

"Joshua did what he had to do to get the win. He ran around the ring and was on his bike all day. Basically, he had Klitschko in the camp and he was a lot like Klitschko: that jab-grab-hold method. That’s all he did tonight," Wilder told The Athletic.

"I’m not coming in, after losing to this guy, to just dance and grab and jab and hold. I’m going to show the world and convince them I am the very best and that no one is close to me, especially with what’s going on in the division right now. It’s a time of proving who is the best. Joshua had many times he could’ve gone for the finish after he landed the right hand.

"When you land the right hand, you’ve tackled the distance. When you land that punch, you know you’re in exact position for the second time around. ‘But he was so hesitant… Joshua’s mentality was to survive. The Klitschko method. The difference is my mentality is that of a beast, a warrior, a king, an emperor – all those things. If he calls himself a king, he’s just on the nicer side of it. This is a brutal sport and that’s how I treat it. I ain’t showing no love for anybody in that ring."
