After claiming the title at the BNP Paribas WTA Finals Singapore presented by SC Global, Caroline Wozniacki also moves up the rankings - to World No.3, climbing three places.
Simona Halep stays on top of the table and is the Year-End World No.1, with Garbiñe Muguruza in the second slot.
Further down the rankings, though, there are plenty of players who are putting together impressive climbs. Here are some of the most notable ranking movers this week:
Mihaela Buzarnescu (+17, No.99 to No.72): The Romanian won the title at the Internationaux Feminins de la Vienne in Poitiers, beating top seed Tatjana Maria in the semifinal in straight sets, 6-4, 6-2, and moving to a new career-best ranking.
Alison Van Uytvanck (+4, No.79 to No.75): The Belgian enjoyed a good run in Poitiers, going in as fourth seed, but stumbled against Buzarnescu in the final, losing in straight sets, 6-4, 6-2.
Nao Hibino (+5, No.97 to No.92): Despite retiring from the final in Liuzhou, Hibino enjoyed a good enough run there to rise five places, including a win over fifth seed Han Xinyun in the semifinal, 6-0, 6-1.
Polona Hercog (+6, No.110 to No.104): The Slovenian went into the Santa Margherita Di Pula as the top seed, and made it as far as the quarterfinals, where she lost to the seventh seed, Austria's Julia Grabher, 7-6(4), 6-2.
Taylor Townsend (+6, No.113 to No.107): The American won the title at the McLeod for Health Florence Open, beating Ysaline Bonaventure in the final, 6-1, 7-5, but could not replicate her form at the WL Amos Sr Tennis Classic in Macon the week after.
Anna Karolina Schmiedlova (+49, No.181 to No.132): The 23-year-old lifted the trophy in Macon, beating Victoria Duval in the final, 6-4, 6-1, and shot up the rankings as she looks to break the Top 100 once again.
