Naomi Osaka’s win over world number one Ashleigh Barty in Beijing at the weekend lifted the Japanese player back into the top three in the new WTA rankings released on Monday.It meant back-to-back WTA Tour titles for the 21-year-old, who won the Australian Open in January, but then failed to match those high standards at the next three Grand Slams. French Open winner Barty retains top spot and even extends her lead following the failure of Karolina Pliskova to get past the first round in China.Osaka’s rise to three means Elina Svitolina, quarter-finalist in Beijing, slips to four.US Open champion Bianca Andreescu, who lost a thrilling quarter-final to Osaka last week, also climbs a place to number five pushing Simona Halep down to six.ATP Rankings as of October 7:1.
