Andy Ruiz Jr shocked the world on Saturday when he recorded a seventh-round win of world heavyweight champions Anthony Joshua!

Anthony Joshua made his debut in America on Saturday night. He was fighting Andy Ruiz Jr at Maddison Square Gardens, with the WBA, IBO, IBF and WBO heavyweight belts all on the line. Ruiz took the fight on just six weeks notice after Jarrell Miller failed two drugs tests.

Ruiz Jr had only ever been beaten once coming into this fight. That was by Joseph Parker who beat him on points. AJ had beaten Parker before but that also went to points which would suggest this was going to be a close contest. Joshua was the favourite going into the fight at 1/25. Nearly everyone was expecting AJ to win this fight with ease and look forward to a fight with either Fury or Wilder.

From the start of the fight, it was clear AJ wasn’t looking his best. Ruiz was able to land some big shots on him which we haven’t been used to seeing. Many of the commentators and ex-boxers said it looked like he had taken his mind off the fight and wasn’t up for it.

However, the British boxer did get the first knockdown of the fight. This was also the first time Ruiz Jr had been knocked down in his career. But almost instantly Ruiz Jr replied and put AJ down on the canvas. If he didn’t know it in the first round then he knew now he was in for a real fight.

Ruiz Jr then continued to dominate from this point. He kept putting the pressure on AJ who couldn’t handle it. In the next three rounds, he would drop Joshua another three times. The Olympic gold medalist looked stunned and had no idea what to do. On the fourth and final time, the referee called a halt to the fight and the world was stunned. The 1/25 favourite had been beaten for the first time in his career!

Ruiz Jr made history with the win as he is now the first ever world heavyweight champion from Mexico. This was considered one of the biggest upsets in boxing history.

AJ is thought to want a rematch with Eddie Hearn mentioning November/December as a potential date. Bet365 have AJ as the favourite again should they fight this year at 2/7 with Ruiz Jr priced at 5/2.
