Britain's Anthony Joshua put on a devastating display to retain his IBF heavyweight crown with a seventh round knockout of American Dominic Breazeale at London's O2 Arena Saturday. Unbeaten Joshua dominated from the start but the 30-year-old Breazeale proved a courageous opponent, absorbing some thunderous blows throughout from the 2012 Olympic super-heavyweight champion before succumbing to Joshua's power. There were signs that Joshua was beginning to get frustrated in the sixth round of his first title defense but he began the seventh with a tremendous barrage of blows that sent his opponent to the canvas. Breazeale, also unbeaten prior to the bout, managed to continue but was floored again by a left and the referee waved an end to the contest without counting. Joshua took his record to 17-0, all by knockout or stoppage, and his classy display offered more evidence to support the belief that the muscular 26-year-old could eventually unify the division. "When you start catching them flush, you know they can feel the shots, and so he was tough," Joshua, who won the title by beating Charles Martin in his previous fight, told reporters. "But this has been tough for me, as two weeks after my last fight I was straight back into the ring. So now I look forward to getting my break. I need some time off." Joshua wobbled Breazeale in the second round with a right hook and again with a stinging shot to the body. A cut and opened up above Breazeale's swollen eye in the third but the American was still throwing punches, even if few of them found their target. Joshua dominated the fourth round, although Breazeale did connect with a straight right to the top of the champion's head in the fifth, exchanging words with the Briton at the bell. Breazeale drew blood from Joshua's nose in the sixth and ended the round on the front foot but the Briton nailed him in the seventh. "I'm making waves in the US now and one day I'm sure (WBC holder) Deontay Wilder and I will get to experience what each other are all about," Joshua, who wore white in memory of heavyweight great Muhammad Ali, said. Joshua's fellow Britain Tyson Fury holds the WBA and WBO belts and was scheduled to fight former champion Wladimir Klitschko in a rematch on July 9 but pulled out because of an ankle injury suffered in training. Deontay Wilder defends his World Boxing Council (WBC) title against fellow American Chris Arreola on July 16. Joshua is expected to make a mandatory defence against New Zealand's Joseph Parker by the end of the year or spring 2017. George Groves won a WBA super-middleweight title eliminator against fellow Briton Martin Murray on the undercard. Groves, a loser in three world title fights, earned scores of 118-110 on all three scorecards after wobbling Murray in rounds eight, nine and 12. Thurman outpoints Porter The last time CBS telecast a fight in prime time, Muhammad Ali was in the ring — 38 years ago. Keith Thurman and Shawn Porter did their best to ensure the wait won't be anywhere near so long for the next such boxing telecast. Thurman defended his WBA welterweight title Saturday night with a 12-round unanimous decision over Porter. The bout was fierce and packed with action from the beginning until the final bell. Both fighters landed precise combinations and also missed wildly. Each was coming off lengthy layoffs, and their eagerness to show their skills made for an entertaining evening. Indeed, some observers were calling it the fight of the year, and the fans at Barclay's Center couldn't have asked for more. Thurman won on all three cards 115-113. The AP also scored the fight 115-113 for Thurman. — Agencies
