Aliaksandra's Sasnovich's breakout run at the Brisbane International was the story of the first week of the season, and she's reaping the rewards of her success in the first WTA rankings update of 2018.
The Belarusian won a staggering seven straight matches in Brisbane - with a pair of Top 20 victories - to reach the biggest final of her career at the WTA Premier level event.
As a result, Sasnovich moves up 35 spots to a new career-high of World No.53, smashing her previous best of World No.87.
Her run in Queensland was stopped in the final by new World No.4 Elina Svitolina, whose title ensured her rise by two spots.
Elsewhere in the first week, ASB Classic runner-up Caroline Wozniacki returns to World No.2 from No.3, the first time she's occupied a place in the top two spots in the WTA rankings in six years.
The Dane had a chance to return to World No.1 last week in Auckland, but Simona Halep's run to the title in Shenzhen, coupled with Wozniacki's defeat to Julia Goerges, ensured the Romanian will remain on top headed to the first Grand Slam of the year in Melbourne.
Here are some of the other notable ranking movers after the first week of the season:
Kaia Kanepi, +20 (No.99 to No.79): The former World No.15 had a strong week in Brisbane, where she was a champion in 2012.
Coming out of qualifying, the six-time Grand Slam quarterfinalist defeated Daria Kasatkina and Lesia Tsurenko in the main draw after winning her three qualifying matches, before falling in the quarterfinals to Karolina Pliskova despite holding a set and a break lead.
Sachia Vickery, +17 (No.122 to No.105): A strong week for the American in Auckland saw her reach her first career WTA semifinal, falling to Wozniacki.
Vickery picked up a pair of Top 50 victories over defending champion Lauren Davis and No.4 seed Agnieszka Radwanska after successfully coming through qualifying in Auckland.
Hsieh Su-Wei, +13 (No.103 to No.90): Hseih also reached the semifinals in Auckland before falling to eventual champion Julia Goerges.
The former World No.23 hadn't reached a WTA semifinal in singles in nearly two years, having last done so at the Taiwan Open in February of 2016, but scored a statement win over No.3 seed Barbora Strycova in the quarterfinals.
Julia Goerges, +2 (No.14 to No.12): Goerges cemented her place as Germany's No.1 with a run to her third straight title, taking home victory at the ASB Classic at the expense of Caroline Wozniacki. Her new ranking of World No.12 is a new career-best.
Maria Sharapova, +12 (No.59 to No.47): The five-time Grand Slam champion returns to the WTA Top 50 this week after a semifinal showing in Shenzhen, where she was stopped by eventual runner-up Katerina Siniakova.
Aleksandra Krunic, +8 (No.53 to No.45): Krunic makes her Top 50 debut after a run to the quarterfinals in Brisbane. The Serb earned a win over top seed Garbiñe Muguruza, who succumbed to cramping in the second round, and has shaved 100 places off her ranking since this time last year.
