Marta Kostyuk beat Jessica Pegula 6-1, 6-4 in 1 hour and 13 minutes on Arantxa Sanchez Stadium on Sunday, eliminating one of the favorites and moving into the fourth round at the Mutua Madrid Open.
Kostyuk, who has won eight straight matches on clay, piled up 20 winners to Pegula’s nine, saved 10 of the 11 break points she faced and converted four of seven break opportunities as she recorded her 13th career Top 10 victory.
The scoreline underscored a match of small margins. Kostyuk took control early, closing the opening set 6-1, and stretched runs to three straight games on three separate occasions to keep Pegula chasing. Pegula managed only 27% of points on her second serve and never recovered the momentum she had built earlier this spring.
After the match Kostyuk said she’s learned how to handle Madrid’s unique conditions. "I think it took me many years to learn how to play Madrid," she said, adding that the city requires adjustment. "It's very tricky, very different conditions here." She credited her tactics for the win: "I'm happy with how tactically played today, and how I used my strengths."
Kostyuk’s straight-set victory continues a swing of form that began months earlier: she beat Pegula 6-0, 6-3 in the semifinals of the Brisbane International in January and entered Madrid on the back of a Rouen title this spring while Pegula had taken the Charleston crown. The two had been a combined 6-0 on clay in WTA events this spring before Sunday’s meeting.
Still, the match did not lack sparks from Pegula. She told reporters she felt good with her ball-striking but not with her strategy. "I actually felt good when I was hitting the ball, but I just don't think I played very smart," Pegula said. "I don't think I was playing the right patterns I needed to play. I was just not happy with the strategy that I was kind of playing." Those words matched the stat line: Pegula managed just nine winners and saw key points slip away.
Kostyuk’s ability to answer pressure moments stood out. She saved 10 of 11 break points and broke Pegula four times on seven break-point chances, a conversion rate that tilted the match decisively. "I think it was just a good wake-up call for me to just think a little bit smarter out there," Kostyuk said, reflecting on the tactical lesson she drew from her own play and from earlier meetings with Pegula. "I played Jessica this year already, and she's such a tough player, such a solid player."
The win sets up a matchup with Caty McNally for a place in the Madrid quarterfinals. McNally reached the fourth round of a WTA 1000 event for the first time in her career after saving two match points against Katerina Siniakova, and will pose a different test with her aggressive net play and left-handed angles.
For Kostyuk the result matters beyond one slot in the draw: back-to-back wins over a top opponent on European clay and a growing mastery of Madrid’s conditions suggest she is turning into one of the tournament’s most dangerous players. If she keeps serving and converting at this level, she will arrive at the quarterfinal doorstep with momentum—exactly what her season’s clay run now promises.
