Porsche Tennis Grand Prix: Elena Rybakina ends Swiatek winning run to set up final clash with Marta Kostyuk

Elena Rybakina ended defending champion Iga Swiatek's 10-match winning streak in Stuttgart on Saturday to reach the final of the clay-court tournament.

Fourth seed Rybakina came through their semi-final clash 6-3, 4-6, 6-3, stunning the Polish world number one who had captured the last two titles at the German event.

Rybakina will face Ukrainian Marta Kostyuk, who defeated Wimbledon champion Marketa Vondrousova 7-6 (7/2), 6-2 in Saturday's second semi-final, for the title.

Rybakina now boasts a 4-2 career head-to-head record against four-time Grand Slam winner Swiatek and will be playing in her fifth final of 2024 on Sunday.

"Like always it was a very tough match," Rybakina said of her opponent. "My serve helped me a lot in important moments. I was fighting for the ball.

"It was such a close match. I'm really happy I managed to win and could show a good game."

Winners of the Stuttgart tournament, sponsored by German automobile company Porsche, receive a car but Rybakina revealed the prize would be of little use.

"I actually don't have a driver's licence," said Rybakina, 24, who has titles to her name this season in Adelaide and Abu Dhabi and runners-up spots at Doha and Miami.

Kostyuk took just one hour 35 minutes to beat world number eight Vondrousova, just a day after coming through a three-set epic against US Open champion and world number three Coco Gauff.

"I don't think a lot of people know but I started my career 0-14 against top 10 players so I'm really trying to catch up," said world number 27 Kostyuk who also eliminated seventh-ranked Zheng Qinwen earlier in the week.

"These are some of the best players in the world in the last year and it's incredible to beat all of them -- and I'm hoping for a Grand Slam too for myself one day."

The 21-year-old Ukrainian will play in her second final of the season, having finished runner-up to Katie Boulter at the San Diego Open in March.
