Unseeded Karolína Muchová stunned world number two Aryna Sabalenka in a three-set thriller to reach her first Grand Slam final against the defending champion Iga Świątek at the French Open in Paris.

Czech Republic's Muchová saved match point at 5-3 in the deciding set on Court Philippe Chatrier, but salvaged the game to hold serve, and went on to twice break her Belarusian opponent, playing as a neutral because of the war in Ukraine, and triumph 7-5 in three hours and 13 minutes.

It was a dramatic finish to a closely-fought contest in which the first two sets both went to tiebreaks.

Sabalenka saved set point at 5-4 with Muchová on serve in the first, but lost the tiebreak 7-5.

The Australian Open champion, who had already enjoyed her best run to date on the clay court Grand Slam by reaching the semi-finals, levelled the match with a 7-5 tiebreak victory in the second set, but her 12-match winning streak at this year's majors came to an end.

For Muchová, her remarkable run to a first Grand Slam final aged 26 came just over a year after being warned by doctors her career may be over.

"There has been many moments, many lows, I would say, from one injury to another," she reflected afterwards,

"For sure when I missed Australian Open last year, and I was in a pretty bad state health-wise, I was working out a lot to try to get back.

"You never know.

"Some doctors told me, you know, maybe you'll not do sport anymore.

"But I always kept it kind of positive in my mind and tried to work and do all the exercises to be able to come back."

World number one Świątek of Poland reached her third French Open final in four years with a 6-2, 7-6 victory in two hours and nine minutes against Brazilian 14th seed Beatriz Haddad Maia.

Haddad Maia had spent more than seven hours extra on court compared to her opponent on their runs to the semi-finals, but became the first player from her country to reach this stage of the women's singles at the French Open since 1966.

She found an early break in the first game, but Świątek immediately replied and proved too strong in the first set.

The second set proved tougher for Świątek, having to save three break points on serve at 4-4 and a set point with Haddad Maia on serve at 6-5 in the tiebreak.

However, Haddad Maia volleyed into the net on set point and Świątek held her nerve to win the tiebreak 9-7 and reach her third French Open final at the age of 22.

The women's singles final is due to be played tomorrow.

Tomorrow's men's singles semi-finals at Stade Roland Garros are set to feature a hotly-anticipated tie between Spain's 20-year-old world number one Carlos Alcaraz and Serbia's Novak Djokovic, who is seeking a record-breaking 23rd Grand Slam at the age of 36.

Olympic champion Alexander Zverev of Germany is also due to face last year's runner-up Casper Ruud of Norway.
