Paris: US Open champion Emma Raducanu is out of the French Open in the second round.
The 19-year-old Raducanu lost to Aliaksandra Sasnovich of Belarus 3-6, 6-1, 6-1.
Sasnovich won 12 of 14 service points in the second set en route to her 16th career victory over a top-20 player.
The 12th-seeded Raducanu failed to convert on five break-point chances at 1-1 in the third set.
Sasnovich advanced to the third round at Roland Garros for the first time. This is her seventh appearance.
The 28-year-old Sasnovich had also beaten Raducanu at Indian Wells last year in the Briton's first match after winning the title at Flushing Meadows.
Azarenka advances
Meanwhile, two-time Grand Slam champion Victoria Azarenka of Belarus reached the third round at the French Open by beating Andrea Petkovic 6-1, 7-6 (3).
The 15th-seeded Azarenka had only 13 unforced errors to Petkovic's 42.
Azarenka has twice won the Australian Open and was a semifinalist at Roland Garros in 2013.
The 34-year-old Petkovic reached the French Open semifinals in 2014 but has not been beyond the third round at any Grand Slam since then. She is a five-time clay-court champion on the tour.
