With the first week of the grass court season in the books, this week's edition of the WTA rankings sees breakthroughs aplenty after some surprising results on the lawns.
Anett Kontaveit and Donna Vekic, champions of the Ricoh Open and Aegon Open Nottingham, respectively, each rise over 10 spots to new career-highs this week. Behind her first career title in 's-Hertogenbosch, Kontaveit rises 13 places from No.49 to No.36 for her top 40 debut, having began the season ranked outside the top 120.
Vekic, whose previous career-high ranking was No.62 in 2013, moves up 12 spots from No.70 to No.58 to cement her place as Croatia's No.3. After reaching the semifinals in Nottingham without dropping a set, Vekic came through three-setters against Lucie Safarova in the semifinals and top seed Johanna Konta in the final to win her second career title.
Here are the other most notable WTA Rankings movers this week:
Natalia Vikhlyantseva (+9, No.74 to No.65) - The Russian snapped a six-match losing streak in a big way in 's-Hertogenbosch, reaching her first career WTA final where she finished runner-up to Kontaveit.
Ranked outside the top 250 at this time last season, Vikhlyantseva rises nine spots to inside the top 70.
Ashleigh Barty (+11, No.88 to No.77) - The Aussie continued her resurgent 2017 in Nottingham, where she reached the quarterfinals before falling to Konta. Barty now sits just one spot off of her previous career-high of No.76, which she set in May of this year.
Magdalena Rybarikova (+10, No.117 to No.107) - Just nine tournaments into her comeback from knee and wrist surgery, the Slovak sits on the cusp of returning to the top 100 after a semifinal showing in Nottingham. After reaching the second round at Roland Garros, the former World No.31 started her grass court campaign with a victory at the ITF $100,000 event in Surbiton, where she scored five wins - including two over top 100 players - without losing a set.
Kristie Ahn (+15, No.131 to No.116) - The American was already having a career year in 2017 and she had her best-ever WTA result in Nottingham. The 24-year-old Stanford grad had never set foot on a grass court before this season, but qualified and reached the quarterfinals without the loss of a set to reach a new career-high ranking.
Ahn rolled past No.8 seed Naomi Osaka in the opening round with the loss of just two games, but saw her run ended by Rybarikova.
Zarina Diyas (+74, No.207 to No.133) - The former World No.31, sidelined for seven months after wrist surgery who began her comeback in February of this year, claimed the biggest title of her career at the ITF $100,000 event in Manchester last week without losing a set. Diyas' run included a semifinal victory over home favorite Naomi Broady before she snapped Aleksandra Krunic's nine-match winning streak in the final.
Krunic also makes a move this week, moving up seven spots to No.94 - marking her return to the top 100 after a two-week stretch that saw her win the WTA 125 title in Bol, Croatia.
Olga Danilovic (+200, No.725 to No.525) - An honorable mention this week goes to the 16-year-old Serbian, who's featured in the top 10 of the ITF junior rankings this year. Playing in her biggest career professional event to date - an ITF $60,000 event in Hodmezovasarhely, Hungary - as a wildcard, Danilovic reached the semifinals.
She ended the 11-match winning streak of former top 30 player Anna Karolina Schmiedlova in the second round, and scored her first-ever win against a top 200 player against No.8 seed Barbara Haas with the loss of just four games in the quarterfinals.
