Poland’s Swiatek needed just 54 minutes to complete her 6-1, 6-0 rout of Veronika Kudermetova and has dropped a total of only five games en route to the fourth round at Indian Wells.
There she will meet Jelena Ostapenko, who out-hit Yulia Putintseva 6-3 2-6 6-3 in their third round match.
“I’m pretty happy that I was so confident,” Swiatek said.
“I was really disciplined, and that’s like the important word for me right now, because like mentally and physically I think it’s pretty hard to do that at the end of the season.”
After the win, Swiatek told reporters she would be donating $50,000 of her prize money to a mental health organisation in honour of World Mental Health Day.
“I would say in sports, for me it was always important to use that kind of help because I always thought that in my mental toughness there is some strength that I can use on court and I can also develop in that manner,” Swiatek said.
