Rybakina outlasts Muchova to reach Indian Wells semis

Wimbledon champion Elena Rybakina survived a stern test from Czech Karolina Muchova before advancing to the Indian Wells semi-finals with a 7-6(4) 2-6 6-4 win on Thursday.

Kazakhstan's Rybakina will face either world number one Iga Swiatek or unseeded Romania's Sorana Cirstea for a place in the final.

In the third, the 10th-seeded Rybakina went up an early break on another untimely double fault by Muchova and held at love to push the advantage to 3-1.

Muchova continued to battle, saving two match points on her serve in the ninth game.

But Rybakina did not miss her third opportunity to secure the win, crushing her sixth ace to end the two-hour, 45-minute contest on a sunny day at the WTA 1000 event in the Southern California desert.

"It was a really tough match today," said Rybakina, who became the first Kazakhstani woman to make it to the tournament's semis.

"I served much better in the third. I didn't start that well at the beginning of the match. I was a bit slower than usual and here
