Croatian heavyweight Filip Hrgović (21-1) upset the odds and the narrative by stopping Moses Itauma (14-1) in the ninth round of their fight for the IBF world title at the O2 Arena in London on Saturday night, becoming the first Croatian heavyweight world champion in history.Coming into the fight, the headlines were all about Itauma, the 21-year-old Brit with a chance to make history by becoming the youngest heavyweight to win a world title since Mike Tyson did so at age 20 in 1986. But Hrgović was the man with the experience — a 2016 Olympic bronze medalist who entered Saturday’s bout with a 20-1 record as a professional. Itauma was 14-0 with 12 wins by knockout; eight of his stoppage victories had come in the first round, and 11 within two rounds. In total, he’d fought just 31 professional rounds.The night was promoted with the tagline “Witness History” — more likely a hint toward Itauma’s opportunity than Hrgović’s. In the end, the Brit’s lack of experience appeared as he emptied his energy stores to the point where he seemed to lose control of his limbs. As Itauma continued attempting to throw power punches, Hrgović knew his opponent had nothing left and went for the kill. With 33 seconds left in Round 9, Itauma’s trainer Ben Davison threw in the towel, leaving Hrgović to celebrate making history.In the early rounds, the fight looked as though it was going to play out the way so many had predicted: With Itauma’s hand speed making his 34-year-old foe look slow and ponderous. Throwing sharp southpaw jabs to Hrgović’s head before landing hard lefts to the Croatian’s body, Itauma seemed unable to miss as he stalked his opponent around the ring.
