Rankings Watch: Anisimova makes Top 20 debut, Ostapenko back in Top 30

Last week saw the Hologic WTA Tour's season of WTA 1000 tournaments kick off with the Qatar TotalEnergies Open. A number of early upsets paved the way to the fourth ever WTA 1000 final between two unseeded players -- though neither champion Amanda Anisimova View Profile nor runner-up Jelena Ostapenko View Profile are exactly unknown quantities.
Anisimova's big-stage breakthrough came at the age of just 17, when the American made the 2019 Roland Garros semifinals. Later that year, she would reach No. 21 in the rankings -- which would remain her career high for over half a decade. In 2021, she slumped to a low of No. 86, but in 2022 surged back up to No. 22.
However, in 2023 Anisimova took a seven-month sabbatical from the sport for mental health reasons. When she returned at the start of 2024, she was ranked No. 373. But her form since coming back has been at a consistently high level. Following her breakthrough appearance in the Toronto WTA 1000 final last August, Anisimova has now achieved her first title at this level in Doha. This week, Anisimova moves up 23 places from No. 41 to crack the Top 20 of the PIF WTA Rankings for the first time at No. 18.
This time last year, former Roland Garros champion Ostapenko had just re-established herself in the Top 10 after a five-year gap. But she struggled with injury in the second half of the year, ending her singles season in September due to an abdominal issue. Last week, having not won consecutive matches since Wimbledon, she fell out of the Top 30 for the first time since 2021.
But the Latvian roared back in style in Doha, dropping just four games in each of her matches against Jasmine Paolini View Profile , Ons Jabeur View Profile and Iga Swiatek View Profile (against whom she now owns a 5-0 record). The six-year, 321-day gap between Ostapenko's last WTA 1000 final at Miami 2018 and Doha 2024 is the longest since the format's inception. She's rewarded with an 11-spot jump from No. 37 to No. 26.
Arango resurgent, Branstine breaks through in Cancun
Colombia's Emiliana Arango View Profile won her first WTA 125 title last week in Cancun and moves up 36 places to No. 133. The 24-year-old reached her career high of No. 109 in November 2023, but had fallen to No. 234 by October 2024. However, a run to the Santa Cruz WTA 125 final in October has spearheaded a surge back up the rankings.
Cancun runner-up Carson Branstine View Profile enjoyed a breakthrough week, defeating Lauren Davis View Profile and Maya Joint View Profile en route to her first WTA 125 final and rising 65 places to a new career high of No. 207. The Canadian was a top junior, where she was ranked No. 4 in the world and won the 2017 Australian Open and Roland Garros girls' doubles titles alongside Bianca Andreescu View Profile . Following a successful college tennis career at Texas A&M University, Branstine compiled a 43-15 record in 2024, including three ITF titles, in her first full pro season. Unranked in November 2023, she ended 2024 at No. 252.
