Peng climbs nine places to close in on top 20

Victory at the Jiangxi Open in Nanchang sees China's Peng Shuai close in on the top 20 in the WTA rankings published on Monday.

Katerina Siniakova of the Czech Republic poses with the trophy after beating Dane Caroline Wozniacki 6-3, 6-4 in the final of the Swedish Open in Bastad on July 30, 2017.

Victory at the Jiangxi Open on Sunday saw China's Peng Shuai close in on the top 20 in the WTA rankings published on Monday.

Peng climbed from No. 32 to No. 23, following her 6-3, 6-2 victory over Nao Hibino of Japan in the final in Nanchang.

The biggest mover, however, was Czech Katerina Siniakova, who rose 17 places to 39th on the back of victory in Bastad.

Siniakova saw off Denmark's Caroline Wozniacki in the final of the Swedish Open 6-3, 6-4, with both players battling injury problems. Both took medical timeouts following the first set as Wozniacki had problems with her left wrist and Siniakova with her right arm.

Siniakova was playing in the Swedish Open final for the second year in a row after losing last year to German Laura Siegemund.

There was almost no change in the women's top 20, meaning Czech Karolina Pliskova maintained the No.1 spot with a lead of almost 1,000 points over Romania's Simona Halep.

Wimbledon champion Garbine Muguruza of Spain is fourth with pregnant former world No. 1 Serena Williams of the United States 15th.

Meanwhile, Novak Djokovic dropped one place to fifth with Swiss Stanislas Wawrinka moving up to fourth in the ATP rankings published on Monday.

Former world No. 1 Djokovic will likely fall further by the end of the year as the Serb has already announced he will not play again this season due to an elbow injury.

The main move saw German Alexander Zverev climb three places to a career-high eighth.

Argentina's Leonardo Mayer was the biggest mover, up 89 places to 49th following his victory in the Hamburg Open.

And there was consolation for German beaten finalist Florian Mayer, who still moved up 45 spots to 56th.

Briton Andy Murray remains top ahead of Spain's Rafael Nadal with Roger Federer of Switzerland third.

In Atlanta, Georgia, John Isner rode an overpowering service game to his fourth Atlanta Open title, beating fellow American Ryan Harrison 7-6 (6), 7-6 (7) on Sunday.

Isner has won two straight ATP tournaments since bowing out of Wimbledon in the second round, and moved up two spots in the world ranking to No. 18.

Isner has claimed one-third of his 12 ATP titles in Atlanta, where he's reached the final in seven of the tournament's eight years and was champion for three straight years from 2013-15. He had 23 aces to the fourth-seeded Harrison's 10.

The 32-year-old Isner won the Hall of Fame Open last week in Newport, Rhode Island.
