Iga Swiatek defeats Coco Gauff to enter SF at the San Diego Open, where Jessica Pegula is waiting.

This season, Iga Swiatek advanced to yet another semifinal. On Friday, the world number one overcame Coco Gauff, 6-0, 6-3, in the San Diego Open quarterfinals. Swiatek finished the proceedings in just 65 minutes. Gauff only won 50% of her first-serve points, while Swiatek won 80% of them and avoided all three of her break points.

On the American’s serve, she went on to convert five of her nine break points. Swiatek was outhit by Gauff in terms of victories (17 to 13 for the Pole). Gauff had almost three times as many unforced errors—26—as the other, which cost her during play. The latter, however, had only nine.

San Diego Open: Iga Swiatek continues to dominate

Swiatek will compete against Gauff’s fellow countrywoman, Jessica Pegula, in the semifinals. The fourth seed defeated Madison Keys in their all-American quarterfinal matchup, 6-4, 7-5, in 1 hour and 33 minutes.

Compared to Keys’ 66%, Pegula won 76% of her first-serve points. On Keys’ serve, she converted three of the three break points she faced while saving four of the five break points she faced. Pegula talked about playing Swiatek after the victory. I’ve played (Swiatek) so much that I feel like I kind of know what to expect.

She plays with great athleticism, aggression, and defense. She performs each task at a very high level. She plays somewhat differently than the girls, and occasionally that can make a difference. You’ve never played a role like her before.

Though I’d like to think that playing her at the end of the year would be preferable. We’ll wait and watch how the game goes. Both seeds lost their respective last-eight matches in the WTA 500 event’s bottom half of the draw, where they were seeded.

Aryna Sabalenka, the third seed, was shocked by Donna Vekic in two hours and 37 minutes, winning 6-4, 6-7(5), 6-1. The Croatian will compete against American Danielle Collins in an effort to advance to the San Diego Open final. In the final match of the day, Collins defeated Paula Badosa, the second-seeded player. After two hours of play, Collins defeated the Spaniard 7-6(5), 6-4.
