Second seed Iga Swiatek exited the Indian Wells Masters a day after tournament No. 1 Karolina Pliskova lost to leave the event wide open on the women’s side of the draw on Tuesday.
The Pole who won Roland Garros as a teenager in autumn, 2020, lost to 2017 Paris champion Jelena Ostapenko 6-4, 6-3 as the Latvian booked into the quarter-finals.
The winner rallied from a break down in each set to pull off the upset in 89 minutes on the slow desert hardcourt.
“I knew it was going to be a very tough match because she’s such a great player, she won a Grand Slam and she’s playing great tennis,” Ostapenko said.
“I really came with a strong mentality to this match. I knew I had to fight for every point, be aggressive and I think I did that pretty well today.”
Ostapenko now stands 2-0 in the rivalry with Swiatek, whom she also defeated on grass in Birmingham in 2019.
“I just tried to serve better because it was a little bit windy and cooler today,” Ostapenko said.
“It was such different conditions to my last (windy) match and I needed some time to adjust.”
American Jessica Pegula scored another minor upset on the day as she eliminated fourth seed Elina Svitolina 6-1, 6-2 in just 64 minutes for her seventh quarter-final of the season.
Pegula fired 19 winners and 14 unforced errors in the rout as Svitolina was weighed down by 27 unforced errors.and lost eight of 14 break points.
Pegula was pleased with her form: “I played really solid with not a lot of errors, and was getting a lot of really good depth on my balls.
“I was coming in when I needed to, serving well when I needed to – it was a great day.”
