Samantha Stosur looks set to drop out of the world’s top 100 after the veteran’s remarkable decade-long French Open run was halted by powerful Russian Ekaterina Alexandrova in the second round.

Stosur had made at least the third round in her last 10 visits to Roland Garros, a streak only matched on the Paris clay among active players by Maria Sharapova.

She looked set to extend that after racing to a one-set lead before the world No.58’s booming groundstrokes found their range in a gutsy 3-6 6-1 6-4 win.
