It took five years for Sloane Stephens to break the Top 10 after reaching No.11 in October 2013 - but it's only taken the American three months after that to breach the next milestone of the Top 5, thanks to her run to the Roland Garros final.
Having survived a stern test from Camila Giorgi, who served for their third-round match twice in one of the best matches of the tournament, Stephens ploughed through the second week in imperious fashion. The 25-year-old defeated Anett Kontaveit, Daria Kasatkina and Madison Keys without dropping a set - and continued this form into the final, going up a set and a break on Simona Halep with immaculate tennis.
Though the Romanian would come back to capture her own maiden Slam title, Stephens can add her Parisian runner-up showing to highlights of a spectacular 12 months that have also seen her become the US Open and Miami champion for the first time - a record that sees her shoot up to World No.4.
Here are some of this week's most notable ranking movers:
Sloane Stephens (+6, 10 to 4): The Roland Garros runner-up is one of two players to have reached multiple Slam finals in the past year, alongside Simona Halep - and hits a new career high as a result. Stephens' move means that each member of the Top 4 (alongside Simona Halep, Caroline Wozniacki and Garbiñe Muguruza) is a reigning Slam holder - the first time this has happened since September 1998, when Australian Open victor Martina Hingis, US Open winner Lindsay Davenport, Wimbledon champion Jana Novotna and Roland Garros titlist Arantxa Sánchez Vicario comprised the top four ranking places.
Madison Keys (+3, 13 to 10): The American's maiden French Open semifinal run sees her return to the Top 10 for the first time since last April. Keys has now reached the final four at every Slam except Wimbledon, and becomes the youngest active player to have reached three Slam semifinals. This is also the first time that the US Open runner-up has reached two major semifinals within a 12-month period.
Maria Sharapova (+7, 30 to 23): Having been ranked outside the Top 50 at the start of May, the Russian capped off a clay swing that has seen her put together her best results since returning to the sport with a Roland Garros quarterfinal - and a boost to the brink of the Top 20.
Mihaela Buzarnescu (+3, 33 to 30): 30-year-old Buzarnescu's stunning defeat of No.4 seed Elina Svitolina in Paris meant that the Romanian became the oldest second-week debutante at a Slam since Jill Craybas at Wimbledon 2005. This time in 2017, the Romanian was ranked No.374 and had never even played a WTA main draw match - but it was exactly one year ago that her ITF $60,000 title in Hodmezovasarhely, Hungary kickstarted a meteoric rise that now sees her hit the Top 30 for the first time.
Katerina Siniakova (+14, 54 to 40): The Roland Garros doubles champion also had a fine showing in singles, scoring a straight-sets win over Victoria Azarenka in the first round and going on to make the third round of a major for the second time in her career following Wimbledon 2016. The Shenzhen runner-up is now just four places off the career high she set last April.
Kaia Kanepi (+9, 52 to 43): Though Kanepi lost in the first round of the French Open to Daria Kasatkina, the US Open quarterfinalist took the title in the ITF $60,000 event in Brescia, Italy during the second week. This time last year, the Estonian was unranked and only just about to embark on her latest comeback from injuries and illness - but now returns to the Top 50 for the first time since June 2015.
Camila Giorgi (+8, 57 to 49): The Italian played one of the best matches of Roland Garros in her third-round loss to Sloane Stephens - but Giorgi adds a career-best showing in Paris to a solid season so far that's also seen her notch up semifinals in Sydney and Prague, and consequently returns to the Top 50 for the first time since June 2016.
Yulia Putintseva (+42, 98 to 56): With her ranking in danger of slipping out of the Top 100 for the first time in three years, the Kazakh admitted during Roland Garros that she had already begun to target ITF events over the summer instead of WTA tournaments. However, a first-round upset of Sloane Stephens in Nurnberg the week before the French Open laid the groundwork for a stunning quarterfinal run in Paris - her second at the clay Slam - and means that Putintseva has avoided having to drop down a level.
Alison Riske (+20, 83 to 63): The American has been resurgent in recent weeks. Following a maiden clay final in Nurnberg, she proceeded to turn heads in the first round of the French Open by reeling off the first five games against No.1 seed Simona Halep. Though Riske would eventually fall in three sets to the eventual champion, she carried her form over on to her beloved grass courts, taking the title at the ITF $100,000 event in Surbiton without dropping a set.
Wang Qiang (+18, 85 to 67): The Chinese No.3's Roland Garros was one in which she overcame a couple of long-standing hurdles. In the first round, she faced No.9 seed Venus Williams - who had ousted her from both the French Open and Wimbledon last year. This time, Wang finally had her moment, winning 6-4, 7-5 - and backed it up by winning her first Slam second-round match at the seventh go for a career-best major showing.
Rebecca Peterson (+21, 97 to 76): This time last year, the Swedish No.2 was only just returning to action following a shoulder injury that kept her on the sidelines for half a year. Her form this year has been irresistible, though: Peterson has compiled a 22-10 win-loss record, including a maiden WTA semifinal in Acapulco in February, and backed that up by qualifying and winning her first Grand Slam match in Paris. She is rewarded with a brand new career high ranking.
Andrea Petkovic (+20, 107 to 87): For the second major in a row, the former World No.9 upset a seed in the first round. Having ousted Petra Kvitova in Melbourne, last year's quarterfinalist Kristina Mladenovic was Petkovic's victim in Paris. The German, who went on to the third round before falling to Simona Halep, reconsolidates herself in the Top 100 as a result.
Tamara Zidansek (+27, 122 to 95): The 20-year-old Slovenian's rise this year has been stealthily spectacular. Ranked No.205 as recently as February, the former junior World No.16 has torn up the ITF Pro Circuit since graduating to the pro ranks, capturing 16 titles there since 2014 - and this year, Zidansek has been translating that to another level. Her WTA main draw debut in Rabat in April was a successful one as she defeated Magda Linette in the first round - and last week, she scored another victory over the Pole in the final of the Bol 125K event to lift her biggest trophy yet. Zidansek becomes the 10th player to crack the Top 100 in 2018 as a result.
Caroline Dolehide (+19, 125 to 106): The 19-year-old American, who took Simona Halep to the brink of defeat in Indian Wells before losing 1-6, 7-6(3), 6-2, has backed that up with a fine clay season - culminating in coming through qualifying in Paris to make her Grand Slam debut, where she defeated Viktorija Golubic in the first round before falling to Madison Keys. Dolehide hits a new career high on the brink of the Top 100 as a result.
Serena Williams (+268, 451 to 183): The 23-time Grand Slam champion's return to the major stage following maternity leave saw her score three fine wins over Kristyna Pliskova, No.17 seed Ashleigh Barty and No.11 seed Julia Goerges before a pectoral injury forced her to withdraw from her fourth-round clash against Maria Sharapova. Just three tournaments into her comeback, Williams is already back in the Top 200.
