Iga Swiatek has routed 25th-seeded Veronika Kudermetova 6-1 6-0 to reach the round of 16 at the WTA Tour 1000 event in Indian Wells.

The second-seeded Swiatek has dropped just five games in two matches in her first visit to the Californian tournament and needed just 54 minutes to get by Kudermetova.

A year to the day since she won her maiden major title at the French Open, the dominant Polish star won 28 of her 33 service points, hit 19 winners and made just seven unforced errors.

“I was just feeling pretty confident,” the world No.4 said.

“But basically, I wanted to make a gift for my psychologist because usually when I lose there is some drama, so let’s just say she has the day off today.”

Latvia’s Jelena Ostapenko, the 24th seed, saw off Yulia Putintseva 6-3 2-6 6-3 to set up a meeting with Switaek.

Fourth-seeded Elina Svitolina survived a tough challenge from Romanian Sorana Cirstea to win 4-6 6-4 7-6 (7-3).

Ukraine’s Svitolina, who won the bronze medal at the Tokyo Olympics, saved 12 of the 16 break point opportunities Cirstea set up in the two hour and 32 minute contest, and had to fight back from 4-2 down in the third set to advance.

American Shelby Rogers thumped Irina-Camelia Begu 6-0 6-2 and will play US Open finalist Leylah Fernandez or Russian ninth-seed Anastasia Pavlyuchenkova for a place in the quarter-finals.
