The 9 youngest women to win multiple WTA 1000 titles: Mirra Andreeva 3rd
Mirra Andreeva keeps writing her name into the history books.
The 17-year-old stunned Aryna Sabalenka to lift her second straight WTA 1000 title in Indian Wells in Sunday, becoming the youngest champion at the tournament this century.
However, Andreeva is now also one of the youngest women to ever win multiple Tier 1/WTA 1000 titles since the tournament format was initially introduced in 1988.
9) Bianca Andreescu – 19 years, 56 days
The most recent entry on this list before Andreeva, former world No 4 Andreescu was a two-time WTA 1000 champion by the age of 19.
Andreescu claimed her first WTA 1000 title – and first WTA title – at Indian Wells in three sets, defeating former world No 1 Angelique Kerber in the final.
The Canadian would then claim her second title at that level later that year, sealing the Canadian Open title aged 19 years, 56 days after Serena Williams retired injured in the final.
Andreescu would win the US Open weeks later but has failed to win a title since then.
8) Steffi Graf – 18 years, 335 days
A true icon of tennis, Graf was yet to turn 19 when she claimed both the Miami Open and German Open titles in 1988.
The German defeated Chris Evert in straight sets to lift the Miami title, before a victory over Helena Sukova on home soil in Berlin.
Graf had already won seven ‘Category 5’ titles before the format changed to Tier 1 at the start of 1988, including previous triumphs in both Miami and Berlin.
Across her career, the 22-time Grand Slam champion won 26 Category 5/Tier 1 titles.
7) Maria Sharapova – 18 years, 333 days
Perhaps the greatest teen star of the 21st century, former world No 1 Sharapova was also yet to turn 19 before triumphing twice at this level.
Already a Wimbledon champion, Sharapova beat Lindsay Davenport in three sets to claim her first such title at the 2005 Pan Pacific Open.
That was followed a year later by the Russian’s first triumph in Indian Wells, with the five-time Grand Slam winner downing compatriot Elena Dementieva in the final.
Sharapova would win 14 Tier 1/WTA 1000 titles across her career.
6) Venus Williams – 18 years, 284 days
One of the most successful players of the past 30 years, tennis legend Williams claimed back-to-back Miami Open titles before celebrating her 19th birthday.
Williams won her first Tier 1 title at her home event in 1998, defeating Anna Kournikova from a set down, and then successfully defended her title with victory against her sister Serena in 1999.
The seven-time Grand Slam champion was just shy of turning 19 at that point, though would later win the Italian Open and Zurich Open before her 20th birthday in 2000.
Williams won nine Tier 1/WTA 1000 titles in total.
5) Jelena Dokic – 18 years, 178 days
Former world No 4 Dokic won six WTA titles across her career, including two Tier 1 titles early on in her career.
The Australian’s first WTA title came at the Italian Open in 2001, with Dokic defeating future world No 1 Amelie Mauresmo in the final.
That was followed later that year by a triumph at the Kremlin Cup, with the Australian overcoming home favourite Elena Dementieva in the final.
Dokic would never win another Tier 1/WTA 1000 title, though reached the Zurich Open final in both 2001 and 2003.

4) Iva Majoli – 18 years, 176 days
One of the most underrated players of the mid-to-late 1990s, former world No 4 Majoli is best remembered for her 1997 French Open triumph.
However, she is also one of the youngest women to win multiple Tier 1/WTA 1000 titles, starting with her victory over Mary Pierce in the 1995 Zurich Open final – her first WTA title at any level.
Majoli was then just 18 years, 176 days when she claimed her second such title at the 1996 Pan Pacific Open, seeing off tennis great Arantxa Sanchez Vicario.
The Croatian would win her third Tier 1 WTA 1000 title at the 2002 Charleston Open – her eighth and final crown on the WTA Tour.
3) Mirra Andreeva – 17 years, 321 days
Thanks to her stunning triumph in Indian Wells, 17-year-old Andreeva is now one of just three women under the age of 18 to seal multiple titles at this level.
The Russian claimed her first WTA 1000 title at the Dubai Tennis Championships in February 2025, seeing off Clara Tauson in the final.
That has now been followed by her incredible Indian Wells victory, beating Iga Swiatek in the last four before victory over world No 1 Sabalenka in Sunday’s final.
Aged 17 years, 321 days, Andreeva is the third-youngest champion in Indian Wells history.
2) Martina Hingis – 16 years, 180 days
Hingis is always near the top in youngest-ever WTA statistics, so it comes as no surprise to see her sit in second place in this countdown.
After two previous Tier 1 final defeats, Hingis claimed her first title at that level at the 1997 Pan Pacific Open, taking home the title after Graf withdrew from the final.
Just weeks later, the Swiss would then claim a second Tier 1 title at the Miami Open, thrashing Monica Seles in the final.
Hingis would go on to win 17 titles at Tier 1/WTA 1000 level – a haul only beaten by Serena Williams.
1) Monica Seles – 16 years, 162 days
One of the greatest teen stars in tennis history, Seles pips Hingis by just 18 days to sit at the top of this countdown – in a record unlikely to ever be broken.
Seles defeated Judith Wiesner to lift her first Tier 1 title at the 1990 Miami Open, a victory that makes her the second-youngest woman to ever triumph at that level.
However, by beating Martina Navratilova in the Italian Open final later that spring, the former world No 1 made history by winning a second title aged 16 years, 142 days.
Alongside her nine Grand Slam titles, Seles would win a further seven Tier 1 titles after her Miami and Rome triumphs in 1990.
