Jan Blachowicz upset the odds with a grinding unanimous points decision over the previously unbeaten Israel Adesanya to retain his world light heavyweight title at UFC 259 in Las Vegas on Sunday. “If I had knocked him out it would have been better, but anyway I love this win because he is one of the best in the world,” said the 38-year-old Polish fighter after the judges scored it 49-46, 49-45 and 49-45 in his favour. It was the first defeat inflicted on the 31-year-old Adesanya, who was stepping up in weight, in his 21-fight career. The New Zealander, the middleweight title holder, was looking to become only the fifth double-weight world champion in UFC history.
