Ranking Movers: Stephens soars, Muguruza on top

Garbiñe Muguruza has stepped up to the top of the WTA Rankings - but US Open champion Sloane Stephens's meteoric rise is the most notable climb of the week.

The American has leapt up 66 places - from 83 to 17 - and it is all the more incredible as she is still on a comeback after foot surgery. Unseeded in New York, she beat eleventh seed Dominika Cibulkova, 16th seed Anastasija Sevastova and ninth seed Venus Williams en route to the final - where she beat her friend and 15th seed Madison Keys.

Here are the other most notable rankings movers this week:

Julia Goerges (+7, No.33 to No.26): Seeded 30th at Flushing Meadows, the German had a good run - she beat Annika Beck 6-1, 6-0, Zheng Saisai 6-2, 6-1, and Aleksandra Krunic 6-3, 6-3 before falling to eventual champion Sloane Stephens in the round of 16.

Daria Kasatkina (+7, No.38 to No.31): The Russian impressed when she knocked French Open champion Jelena Ostapenko out in New York, triumphing in straight sets 6-3, 6-2. She departed the tournament in the round of 16, though, losing 6-4, 6-4 to Kaia Kanepi.

Jennifer Brady (+26, No.91 to No.65): The 22-year-old had the home crowd behind her at the US Open, helping her to wins over Andrea Petkovic (6-4, 3-6, 6-1), 23rd seed Barbora Strycova (6-1, 6-1) and Monica Niculescu (6-3, 4-6, 7-6). She came up against then-World No.1 Karolina Pliskova in the round of 16, though, losing 6-1, 6-0 in just 46 minutes.

Aleksandra Krunic (+11, No.78 to No.67): The 24-year-old got off to a flying start in New York, beating seventh seed Johanna Konta 4-6, 6-3, 6-4, following that up with a straight-sets win over Ajla Tomljanovic, 6-3, 6-2. Her run was finally halted by Germany's Julia Goerges.

Maria Sakkari (+13, No.95 to No.82): Greece's Sakkari had her best-ever run at the US Open, starting with a 6-3, 6-4 win over 24th seed Kiki Bertens. She beat Arina Rodionova 7-5, 6-3 in the round of 64, but was eventually knocked out by Venus Williams 6-3, 6-4. 

Kateryna Kozlova (+35, No.118 to No.83): The No.5 seed claimed the title at the Dalian Open, beating former World No.2 Vera Zvonareva 6-4, 6-2 in the final. She also qualified for the US Open, winning her first-round match against Irina-Camelia Begu 6-2, 7-6, before falling to eventual quarterfinalist Anastasija Sevastova 6-4, 6-4.
