Moscow champion Belinda Bencic made a late surge up the ranking to break into the Top 8 just in time to qualify for the Shiseido WTA Finals Shenzhen.
The Swiss needed to reach the final of the Kremlin Cup to stand a chance of reaching the event but went a step further by lifting the title thanks to a 3-6, 6-1, 6-1 success over 2014 champion Anastasia Pavlyuchenkova.
As such, she has climbed three spots on the Rankings, overtaking Kiki Bertens, who was her big rival heading into last week, Serena Williams and Elina Svitolina to leap to WTA World No.7 – matching her career best.
While Bencic is threatening to scale previously unattained heights, Jelena Ostapenko was at the BLG BNP Paribas Luxembourg Open busy continuing her surge back up the Rankings. A former WTA World No.5, the Latvian endured a difficult 2019, which she finished impressively as she claimed silverware off the back of an emphatic 6-4, 6-1 success over Julia Goerges.
In addition to the trophy, the 22-year-old has reclaimed the Top 50 status that she lost in July, charging 19 places up the Rankings to WTA World No.44.
Karolina Muchova (+9, No.35 to No.26): The Czech beat seeds Donna Vekic and Ekaterina Alexandrova as she reached the semifinals of the Kremlin Cup.
Anastasia Pavlyuchenkova (+10, No.40 to No.30): Had a week to remember in Moscow as she came within a set of lifting the title before losing out to Bencic. Four of her five matches went the distance, with a first-round come-from-behind win over No.7 seed Maria Sakkari the highlight.
Elena Rybakina (+6, No.43 to No.37): Broke into the Top 40 for the first time thanks to her run to the semifinal of Luxembourg. The Kazak lived up to her No.3 seeding before being beaten by Goerges.
Kristina Mladenovic (+6, No.45 to No.39): The Frenchwoman scored impressive three-set wins over Anastasija Sevastova and No.2 seed Kiki Bertens at the Kremlin Cup but found Bencic to strong in the final four.
Anna Blinkova (+7, No.66 to No.59): The 21-year-old won impressively through to the semis in Luxembourg and even took the opening set against Ostapenko, though the Latvian proved too strong in the end.
Peng Shuai (+17, No.94 to No.77): Continues to surge back into the Top 100 off the back of winning an ITF event in Suzhou.
Lin Zhu (+11, No.106 to No.95): Beaten by Peng in the final of Suzhou but has still enjoyed a healthy jump into the Top 100.
Kaia Kanepi (+12, No.109 to No.97): Qualified impressively for the Kremlin Cup, not dropping a set in three rounds, then defeat Timea Babos in the opening match. Claimed the opening set against Bertens but was ultimately edged out by the No.2 seed.
Kirsten Flipkens (+21, No.120 to No.99): The Belgian also qualified in Moscow without the loss of a set. She negotiated two main draw rounds, eliminating Dayana Yastremska, but found Bencic too strong.
