Roland Garros champion Barbora Krejcikova was waylaid on Monday by an inspired French teenager, with the Czech losing her Grand Slam title 1-6, 6-2, 6-3.

Nice-born 19-year-old Diane Parry, ranked 97th, did the damage to the holder, taking just under two and a quarter hours to dethrone last year’s surprise winner.

Parry broke six times in the first-round match, earning her second career win at a major from six outings.

Krejcikova was competing for the first time since February due to a run of injuries and paid the price for her rusty game with 45 unforced errors.
