Simona Halep, the 2018 champion, and American Danielle Collins are the latest big names to crash out of the womenn’s singles at the French Open.

Halep came unstuck against China’s Qinwen Zheng in three sets while Collins, the No.9 seed, won just seven games against her compatriot Shelby Rogers, losing 6-4 6-3.

Collins reached the final of the Australian Open this year, where she was beaten by Ash Barty.

So swift has been the exit of the women’s top seeds that only three of the top 10 remain: Iga Swiatek (No.1), Paula Badosa (No.3) and Aryna Sabalenka (No.7).

Poland’s Swiatek, the world No.1 and in the form of her life, brushed aside Alison Riske of the US, 6-0 6-2, to take her winning streak to 30 matches.

It’s the longest winning run in women’s tennis since Serena Williams won 34 in a row in 2013.

Halep’s ranking has fallen since her victory in Paris four years ago, however, and the No.19 seed was beaten 6-2 2-6 1-6 by the 19-year-old Zheng.

Spain’s Badosa reached the third round by beating Kaja Juvan, of Slovenia, 7-5 3-6 6-2.

Madison Keys justified her No.22 seeding when she advanced to the third round with a 6-4 7-6 (7-3) win over Frenchwoman Caroline Garcia.

The American, a semi-finalist at Roland Garros in 2018, will next face the No.16 seed, Elena Rybakina, the only woman with more aces than Keys this season.
