PARIS — Angelique Kerber won't complete a career Grand Slam this year.
Still hampered by a right ankle injury, the three-time Grand Slam winner lost in the first round of the French Open on Sunday as the clay-court major began with an upset.
The fifth-seeded German lost 6-4, 6-2 to an 18-year-old Roland Garros beginner, Russian Anastasia Potapova, on Court Philippe Chatrier.
Kerber's preparations for Roland Garros, where she never advanced past the quarterfinals, were hampered by the injury she suffered at the Madrid Open last month.
''Of course this is not my excuse and everything,'' Kerber said.
