Elina Svitolina continued her mastery over Johanna Konta, and now will play for a spot in the 2019 US Open final.
The fifth-seeded Ukrainian improved to 5-0 against Konta with a resilient 6-4, 6-4 win against the 16th-seeded Brit, who was trying to reach her first US Open semifinal and become only the sixth active female player to reach all four Grand Slam semifinals.
Konta had overcome prior unfavorable head-to-heads already this US Open, beating Karolina Pliskova for only the second time in eight tries.
But Svitolina, who reached her first Slam semifinal at Wimbledon, was too consistent and too steady in Arthur Ashe Stadium. The 24-year-old will face the winner of six-time US Open champion Serena Williams and 18th seed Qiang Wang of China, who headline Tuesday's night session in Ashe.
"Not every day you're playing quarterfinal of a Grand Slam. And to win that, it's something special. Yeah, just very happy the way I handled the pressure," Svitolina said. "(I was relieved) I could serve it out, because I had the match point on 5-3. I was very close but in the same, you know, I was very far because to serve it out is definitely very tough under the pressure."
Svitolina responded to everything Konta threw at her from the back of the court, rallying from both sides and challenging Konta's forays forward.
Konta tried to mix it up and take Svitolina out of her rhythm, tossing in backhand slices. But too often the Brit left them short or floated them to the Ukrainian, who happily stepped in the court to take control.
"That was the probably the best I felt her play against me," Konta said. "She just made me play that extra ball."
Svitolina finished with 16 winners to 13 unforced errors, compared to 35 unforced errors and 24 winners from Konta.
With boyfriend Gael Monfils courtside, Svitolina passed the baton to the Frenchman, who will play in his own quarterfinal on Wednesday against Italy's Matteo Berrettini.
