Beijing: Naomi Osaka claims dominant win in 1st match with Serena Williams' ex-coach
Now, the four-time Grand Slam champion is set to meet No. 21 seed Yulia Putintseva, who had a first-round bye. Against the Kazakh, the former world No. 1 has two wins and three losses but it should be noted that she ended on the winning side when they clashed at the Billie Jean King Cup earlier this year.
