PARIS – The ball landing at Barbora Krejcikova's feet on match point appeared to come down behind the baseline.
The linesman thought so and called the shot long. A TV replay confirmed as much, and the unseeded Krejcikova was so sure she raised her arms in triumph to celebrate a berth in her first Grand Slam final at the French Open.
Chair umpire Pierre Bacchi disagreed. He reversed the call, sparking a fresh round of debate about video replay and briefly delaying Krejcikova's victory.
Tennis was spared an unjust result five points later, when she hit a backhand winner to close out the biggest victory of her career. The Czech saved a match point midway through the final set and outlasted No. 17-seeded Maria Sakkari of Greece, 7-5, 4-6, 9-7.
“I always wanted to play matches like this,” Krejcikova said.
She must like roller coasters, too. Her opponent Saturday will be 29-year-old Russian Anastasia Pavlyuchenkova, who also advanced to her first major final by beating unseeded Tamara Zidansek, 7-5, 6-3.
It was only the second time in the professional era that there were four first-time Grand Slam women semifinalists at a major tournament, and the first time since the 1978 Australian Open.
The men's semifinals today include a showdown between 13-time champion Rafael Nadal and 2016 winner Novak Djokovic. It's their 58th meeting, and a rematch of last year's Roland Garros final. The other semifinal will match No. 5 Stefanos Tsitsipas against No. 6 Alexander Zverev, and one of them will have a shot Sunday at his first Grand Slam title.
Krejcikova, a two-time major doubles champion ranked 33rd, is playing singles in the main draw of a major tournament for just the fifth time. The No. 31-seeded Pavlyuchenkova, by contrast, has played in more majors before reaching a final – 52 – than any other woman.
A top-20 player as a teen, Pavlyuchenkova had been 0-6 in major quarterfinals before finally surmounting that hurdle Tuesday, and was steadier than the big-swinging Zidansek in their semifinal.
“I wanted this so much that right now I don't feel anything,” Pavlyuchenkova told the crowd in French.
Krejcikova's run to the final is equally improbable.
“It sounds incredible,” she said. “I cannot believe it. It's actually happening.”
A protégé of the late Grand Slam champion Jana Novotna, Krejcikova seeks to become the first Czech woman to win Roland Garros since Hana Mandlikova in 1981.
She's also bidding to become the first woman to win both in doubles and singles at Roland Garros since Mary Pierce in 2000. She and Katerina Siniakova have advanced to the semifinals today.
