He'll have a lifetime to celebrate one of boxing's biggest stunners in heavyweight history.
Ruiz flattened Anthony Joshua twice in the seventh round and capped one of boxing's biggest upsets to win his share of the heavyweight championship Saturday night (local time) at Madison Square Garden.
Ruiz won it at 1:27 by TKO in the seventh round to become the surprise champ in a bout that had shades of Buster Douglas' upset over Mike Tyson in 1990. Ruiz barely was on anyone's heavyweight radar when he was summoned as a replacement to fight champion Joshua in front of a packed Garden.
All he did was dominate the British champion.
The 270-pound Ruiz knocked down Joshua twice in the third round and did it two more times in the seventh before referee Mike Griffin ended the fight.
He stepped in after fighting on April 20, when he stopped Alexander Dimitrenko. Jarrell Miller's failed drug tests sent the challenger to the sideline.
Ruiz (33-1, 21 KO's) seized the opportunity and made boxing history to win the WBA/IBF/WBO/IBO championships.
Ruiz, the first heavyweight of Mexican descent to win a heavyweight title, raised his arms in celebration and jumped around the ring as his corner quickly mobbed him and a wild celebration kicked off.
When ring announcer Michael Buffer announced the name of the judges "should this fight go the distance," fans laughed at the ridiculous possibility as Ruiz was nearly a 30-1 underdog.
Joshua and Ruiz were both knocked down in an electrifying third round that had the sellout crowd of 20,201 howling with each heavy hit. Joshua knocked down Ruiz early in the round and the promise of an early finish seemed horizon.
Ruiz, his trunks a bit too low for his portly frame, came right back and used an overhand right that stunned the champ and sent him to the canvas. Joshua recovered only to get pummeled in the corner and loose his legs. Ruiz knocked him down again in the final ticks of the round as fans in a stunned Garden crowd screamed "Oh my God!"
Again, Joshua beat the count but the bell saved the Brit from a going a second longer in his weakened state. Had it not been a championship fight, perhaps Griffin would have stopped the bout.
Alas, for Joshua, it went on.
Ruiz, whose father, a native of Mexico, got him into the gym when he was 6 and had his son in bouts a year later, stunned the boxing world. Johsua was the fan favourite and had all the hype for his first fight in the United States.
NBA star Kyrie Irving and rapper Meek Mill were among the celebrities in the house expecting Joshua to roll to a win and set up more ambitious, lucrative bouts against the likes of Tyson Fury, Deontay Wilder and a few other potential opponents.
Wilder, owner of the WBC crown, decided to give Luis Ortiz a rematch. Ortiz battered Wilder for parts of their fight in early 2018 before running out of gas and getting knocked out.
Wilder tried to steal the headlines this week when he announced his rematch with Fury was set for 2020. Wilder and Fury fought to a split draw in December in Los Angeles, with Wilder retaining his WBC heavyweight title after knocking down his British challenger twice.
Joshua instead heads toward a likely rematch against Ruiz later this year.
