Aryna Sabalenka does not waste her time against Qinwen Zheng in the quarterfinals of the US Open

It was the Sabalenka Express on the Arthur-Ashe court. The 26-year-old Belarusian, a regular in the last four of Grand Slams for two years now, did not hold back in her victory over Qinwen Zheng, 21, world number 7 and gold medalist at the Paris Olympic Games. The WTA number 2, finalist in New York last year, took 36 minutes to take the first set, 6-1, and 37 for the second, 6-2.
