Sixth-seed Bianca Andreescu was dumped out of the French Open in the first-round on Monday, losing a marathon three-set clash to Slovenia’s world number 85 Tamara Zidansek.

Zidansek, who will face American Madison
Brengle in the second round, won 6-7 (1/7), 7-6 (7/2), 9-7 after three hours
and 20 minutes.

Canada’s Andreescu, the injury-plagued 2019
US Open champion, had been a fitness doubt for the tournament after pulling out
of an event in Strasbourg last Wednesday.

But she was forced into a gruelling
deciding set against Zidansek, which saw the world number seven fail to serve
out the match at 5-4 and then save a match point two games later.

Zidansek created two more match points in
the 16th game of the third set and needed only one to wrap up victory.

The longest women’s singles match in French
Open history remains Virginie Buisson’s first-round win over fellow Frenchwoman
Noelle van Lottum in 1995, which lasted four hours and seven minutes.
