Aryna Sabalenka got her title defence at the Madrid Open off to a solid start on Thursday.

The Belarusian, who is among the favourites for Roland Garros later this year, saw off American Peyton Stearns 7-5, 6-3 at the Caja Magica.

Already a three-time winner in Madrid, Sabalenka is aiming to become the first player to claim four titles at the tournament.

The world number two will look to keep her momentum going when she faces Romania’s Jacqueline Cristian in the third round.

Even before that match, Sabalenka has already made history by becoming just the third player to hit 100 main-draw wins in WTA 1000 events since their introduction back in 2009. She joined Simona Halep (188) and Victoria Azarenka (180) on that list.

Aryna Sabalenka reached another milestone on Thursday, becoming only the third player to reach 50 WTA 1000 matches while holding the world number one ranking.

Since the WTA introduced the 1000 format in 2009, only Serena Williams and Iga Swiatek have previously reached that milestone, according to OptaAce.

Sabalenka has now spent a total of 87 weeks at the top of the rankings, which is already well past Swiatek’s mark of 75 weeks.

Looking further ahead, Sabalenka’s path could lead her into a matchup against either Anhelina Kalinina or Naomi Osaka in the fourth round.

If she does face Osaka, it would be their third meeting. The head-to-head stands at one win each, but Sabalenka came out on top in their most recent clash at Indian Wells last year.
