World number two Aryna Sabalenka demolished Olympic gold medallist Zheng Qinwen to reach a fourth successive US Open semi-final on Tuesday. Australian Open champion Sabalenka, runner-up to Coco Gauff in New York last year, triumphed 6-1, 6-2 and will take on Emma Navarro of the United States for a place in the final. It will be a ninth career semi-final at the Slams for the 26-year-old from Belarus. She also defeated the Chinese star at the same stage of the US Open in 2023 before going on to beat the 21-year-old again in the Australian Open final in January.
