Ruiz Jr. stuns Joshua in 7th for heavyweight titles

(2:23)NEW YORK -- It may not go down as an upset the magnitude of Buster Douglas knocking out Mike Tyson for the heavyweight world title, or even Hasim Rahman drilling Lennox Lewis to do the same, but Andy Ruiz Jr. knocked out Anthony Joshua in the seventh round to take his three heavyweight belts in an absolute shocker on Saturday night.Sold-out Madison Square Garden was packed with 20,201, including many of Joshua's British countrymen who had made the trip expecting to see him smoke Ruiz, who closed as an 11-1 underdog, according to Caesars. The sky is the limit, baby."Ruiz survived a knockdown in the third round and rallied to drop Joshua twice later in the round and then twice more in the seventh before stopping Joshua in a shocking scene.Ruiz became the first fighter of Mexican descent to win a heavyweight world title and did so in the most dramatic fashion."That was my first time getting dropped on the floor. Mexico has its first heavyweight champion of the world, and we made history," Manny Robles, Ruiz's trainer, said.The chiseled 6-6, 247-pound Joshua (22-1, 21 KOs), 29, was making his seventh title defense and his much-anticipated United States debut after regularly selling out stadiums in the United Kingdom. Leon Spinks defeated Muhammad Ali as a 10-1 underdog"As soon as Andy dropped him, he really slowed down," Robles said.But by the start of the fourth round, Joshua seemed OK as he lashed Ruiz with a left hook that buckled him.Ruiz landed a left hand early in the sixth round that buzzed Joshua, who backed up and looked to stay away. "I just wanted to listen to the game plan."In the seventh round, they were both in attack mode when Ruiz hurt Joshua and unloaded a dozen unanswered punches that finally dropped an exhausted Joshua.He managed to beat the count, but Ruiz floored him again, sending him to one knee. I did not want him to fight at midrange and put himself in front of the big punches."Ruiz jumped up and down and celebrated wildly in the ring with Robles and the rest of their team after having authored one of the biggest upsets in recent boxing history.According to CompuBox, Ruiz landed 56 of 206 punches (27 percent) and Joshua connected with 47 of 176 (27 percent).At the time of the stoppage, Ruiz led 57-56 on two scorecards and Joshua was up 57-56 on the third card.Joshua has the contractual right to a rematch and said he wants it."One hundred percent. It makes the fall fight a must win."Ruiz said he is game for a second go with Joshua as much as he campaigned for the shot on Saturday after Miller fell out.
