PARIS -- Australian Open champion Angelique Kerber has lost in the first round at the French Open.
The third-seeded Kerber was beaten 6-2, 3-6, 6-3 by 58th-ranked Kiki Bertens of the Netherlands on Tuesday.
It's the second time in three years that the Australian Open women's champion has lost in the first round at Roland Garros -- the same thing happened to Li Na in 2014.
Kerber received treatment on her left shoulder at the changeover as she trailed 3-0 in the deciding set. The left-handed Kerber then briefly left the court and returned to win her service game but could not break back and lost the match.
Bertens arrived at Roland Garros in fine form, having won the title last week in Nuremberg by coming through the qualifying stages.
Kerber arrived in Paris on the back of early losses in both Madrid and Rome. Last week she pulled out of the Nuremberg tournament because of her shoulder injury.
