Sisters Mirra and Erika Andreeva will meet for the very first time on the WTA Tour this week, with a round two clash between the two set to take place at the Wuhan Open.
Ahead of the interesting clash between the two teen stars, we look at five other sets of sisters who have played each other on tour.
Venus Williams vs Serena Williams
There was nowhere else we could start than Venus and Serena Williams, two tennis icons and legends who helped usher in a new era of tennis in the early 2000s.
Neither of the two ever had a rival quite like each other, with the 31 meetings between the pair the most times either player faced an opponent on the WTA Tour.
Younger sister Serena had the better of their rivalry, winning 19 of their 31 matches – including seven of their nine Grand Slam singles finals.
Serena also won their last meeting in Lexington in 2020, though they did combine to win 14 women’s doubles Slams and three women’s doubles Olympic gold medals.
Agnieszka Radwanska vs Urszula Radwanska
Outside Venus and Serena, Agnieszka and Urszula Radwanska were among the most prominent WTA siblings in recent years.
Older sister Agnieszka reached a high of world No 2 and was a finalist at Wimbledon in 2012, with Urszula ranked 29th at her peak
The former was the more successful of the two and won three of their four career meetings, including their sole Grand Slam meeting in the opening round of the 2011 US Open.
However, it was Urszula who won the first-ever meeting between the two at WTA level, winning in straight sets at the 2009 Dubai Tennis Championships.

Karolina Pliskova vs Kristyna Pliskova
Another set of famous WTA siblings to emerge in recent years, Karolina and Kristyna Pliskova aren’t just sisters – they are identical twins.
The pair teamed up for doubles action in the past, though on the singles court, it was Karolina who found more success.
She was the world No 1 for eight weeks back in 2017 and reached two Grand Slam finals, at the 2016 US Open and 2021 Wimbledon.
But it was former world No 35 Kristyna who won their only meeting in a WTA-level tournament, prevailing in three sets when they met at the 2019 Birmingham Classic.
Kateryna Bondarenko vs Alona Bondarenko
Two of the most successful Ukrainian players in tennis history, Kateryna and Alona Bondarenko memorably teamed up to win the 2008 Australian Open women’s doubles title.
Both also found success at singles, with Kateryna winning two WTA Tour titles and reaching world No 29, while Alona won two WTA titles and was ranked as high as 19th at her peak.
The sisters met multiple times across their career, including two meetings in official WTA Tournaments.
Alona beat her younger sister in the opening round of the 2006 Bangalore Open, but Kateryna prevailed when they met in round one of the Prague Open in 2009.
Alona and Kateryna’s older sister, Valeria, was also a tennis player.
Katerina Maleeva vs Manuela Maleeva vs Magdalena Maleeva
We end our list with Bulgarian stars Katerina, Manuela, and Magdalena Maleeva, who were all ranked inside the world’s top 10 at some point during their careers.
Manuela was the most successful, reaching world No 3 and winning 19 WTA singles titles, while middle sister Katerina is a former world No 6 and 11-time tour champion, and youngest sister Magdalena is a former world No 4 and winner of 10 tour titles.
It was Manuela who had the better of both of her younger sisters, winning eight of her nine contests versus Katerina and both of her matches against Magdalena.
Meanwhile, Katerina did not drop a set in her four matches against Magdalena, including two meetings at the US Open and an Australian Open clash.
