Ashleigh Barty has become the 10th Australian player to crack the Top 10 in the latest edition of the 2019 WTA Rankings following her brilliant title run at the Miami Open.
The 22-year-old's Florida fortnight saw her rack up three Top 10 wins en route to lifting the trophy, including a first triumph at the fifth attempt over Petra Kvitova and a straight-sets final defeat of Karolina Pliskova, as well as victories over rising teenager Dayana Yastremska, compatriot Samantha Stosur - the last Australian woman to be ranked inside the Top 10 - and erstwhile junior rival Anett Kontaveit.
Barty's first Premier Mandatory championship is the fourth and biggest title of her career to date, and the latest in a series of milestones she has hit over the last five months following a first title above International level at the Zhuhai Elite Trophy to round off 2018, a second Premier final in Sydney and a maiden Grand Slam quarterfinal at the Australian Open.
Here are the notable movers in the WTA Rankings for the week commencing 1 April, 2019.
Karolina Pliskova (+3, 7 to 4): The former World No.1 defeated Simona Halep to make the first Premier Mandatory final of her career in Miami, continuing a superb run of consistency that has seen her reach at least the quarterfinals of every tournament she has played in 2019 so far. Consequently, the Czech returns to her highest ranking since the first week of the 2018 season.
Kiki Bertens (+2, 8 to 6): A fourth-round run in Miami scores Bertens another new career-high ranking this week, and she is now just one spot off the highest ever ranking achieved by a Dutchwoman: Betty Stove's World No.5 peak in 1977.
Ashleigh Barty (+2, 11 to 9): The last Australian woman to be ranked inside the Top 10 was Samantha Stosur in May 2013 - Barty's third-round victim this fortnight en route to the 22-year-old's biggest career title in Miami.
Anett Kontaveit (+5, 19 to 14): Kontaveit's semifinal showing in Miami has led to both a personal and national milestone: her new career high of World No.14 is also the highest ranking ever held by an Estonian player, beating Kaia Kanepi's peak of World No.15 by one spot. Last week marked the third time within the past year that Kontaveit had made the final four or better in a Premier 5 or higher tournament, following her Rome semifinal last May and her run to the Wuhan final in September.
Wang Qiang (+2, 18 to 16): The 27-year-old made the Miami quarterfinals for a career-best result outside Asia, and consequently hits a new career high. Wang is the fourth-best ranked Chinese player in history, behind only Li Na, Peng Shuai and Zheng Jie.
Bianca Andreescu (+1, 24 to 23): The Indian Wells champion extended her winning streak to eight, including a first-round comeback from match point down over Irina-Camelia Begu and a third-round reprise of the Indian Wells final over Angelique Kerber, before being felled by injury in the fourth round of Miami - and hits another career high as a result.
Hsieh Su-Wei (+3, 27 to 24): The Chinese Taipei No.1 did not score a win over a Top 10 player until she was 31, over Johanna Konta at Roland Garros 2017 - but less than two years later Hsieh has now racked up six, including a second triumph over a reigning World No.1 when she defeated Naomi Osaka in the Miami third round en route to her first Premier Mandatory quarterfinal. The 33-year-old is now just one spot off the career-high ranking she originally set in February 2013.
Yulia Putintseva (+6, 44 to 38): The Kazakh's fourth-round showing in Miami included an upset of Dubai champion Belinda Bencic for her 12th career Top 20 win, and second of the season so far, and moves her up to her highest ranking since May 2017.
Marketa Vondrousova (+16, 59 to 43): Just over one year ago, Vondrousova cracked the Top 50 for the first time with a fourth-round showing in Indian Wells; 54 weeks later, the Czech teenager is firmly back on track following a slump last summer, returning to the Top 50 - and hitting a new career high - in style with consecutive quarterfinal runs in Indian Wells and Miami.
Vitalia Diatchenko (+10, 106 to 96): A title run at the ITF W60 event in Croissy-Beauborg last week, including a win over former World No.57 Tereza Smitkova in the semifinals, has returned the 28-year-old Russian to her highest ranking since September 2015.
Misaki Doi (+11, 112 to 101): A prolonged slump saw the former World No.30 dip as low as No.328 last June - but Doi has roared back over the past nine months. Last fortnight, the Japanese player saved four match points in her first qualifying round against Anastasia Potapova en route to a second-round showing in the main draw, and rises to her highest ranking since September 2017.
Elena Rybakina (+20, 163 to 143): The 19-year-old Kazakh turned heads when, as a qualifier ranked World No.450, she stunned Caroline Garcia in the second round of St. Petersburg last February for a maiden Top 10 victory. This year, Rybakina's rise is continuing: she has racked up three titles on the ITF World Tour in 2019 so far - a W60 in Launceston and W25s in Moscow and Kazan, the latter of which has propelled the teenager to a new career high.
Wang Xiyu (+20, 190 to 170): The reigning US Open junior champion was awarded a wildcard into Miami, and used it to score her third Top 100 victory over Olympic gold medallist Monica Puig in the first round. 18-year-old Wang climbs to a new career high as a result.
Cori Gauff (+73, 456 to 383): The 15-year-old American became the youngest player to win a WTA main draw match in nearly a decade in Miami - since a 14-year-old Madison Keys defeated Alla Kudryavtseva at Ponte Vedra Beach in 2009 - with her three-set first-round victory over fellow wildcard Catherine McNally, a repeat of last year's Roland Garros junior final result. Gauff, who reached her first ITF World Tour final at the Surprise W25 in February, is the youngest player to currently hold a world ranking.
