World No.1 Iga Swiatek is through to her first semifinal at the Mutua Madrid Open after a 6-0, 6-3 win over Croatia's Petra Martic.
Swiatek was comprehensive from start to finish against No.27 seed Martic, who'd upset former Roland Garros champion and No.11 seed Barbora Krejcikova to earn her shot against Swiatek.
But after just 69 minutes, the World No.1 moved through to set up a semifinal match against Veronika Kudermetova; Kudermetova, seeded No.12, knocked out No.3 seed and defending finalist Jessica Pegula earlier in the day.
"I feel like I'm playing better and better every day," Swiatek said afterwards. "This is pretty great, because I didn't know if that was going to be possible at the beginning of the tournament. But I was patient and I was hoping to get that feeling, and today was for sure a good day."
Read on for more about Swiatek's quarterfinal win, by the numbers.
