Russia's Karen Khachanov was fortunate to avoid disqualification from the European Open on Friday when he smashed his racquet into the umpire's chair during a fiery quarter-final loss to Britain's Dan Evans. Khachanov, the third seed, had a match point in the second set but was furious when a line call went against him. He kicked out at the net and clattered his racquet into the chair of umpire Adel Nour. "It's a joke. Everyone can see it was out. Are you drunk today?" Khachanov screamed at the official before the tie went to a decider. Evans went on to win 3-6, 7-6 (7/2), 6-4 and next faces France's Ugo Humbert who claimed a 6-3, 7-6 (7/2) win over qualifier Lloyd Harris of South Africa. Australian eighth seed Alex De Minaur beat Marcos Giron of the United States 6-3, 6-0 and will face Bulgarian fourth seed Grigor Dimitrov. Dimitrov progressed when Canada's Milos Raonic withdrew injured. dj/pb
