CoCo Vandweghe owns a variety of shots, but just one game plan, said Karolina Pliskova.

The 20th-seeded American saved a set point toppling world No. 1 Pliskova, 7-6 (4), 6-3, powering into her first US Open semifinal with a spirited victory that will end the Czech’s reign as world No. 1.

Pliskova: No Change Losing No. 1

Vandeweghe, who hired former Wimbledon champion Pat Cash as coach at the start of the grass season in June, is trying to channel her energy and intensity into positive action.

Pliskova said she wasn’t surprised by Vandeweghe today and views the American as a one-plan player.

“It didn't change. Still the same,” Pliskova said of Vandeweghe. “I think she just have one plan, so either it's working or it's not. I think was just much better today.

“Like I said, her game doesn't surprise me at all. I think there was no changes. Even when she changed coach, I think, for me, nothing change. I think she can still do mistake. She can do winners, do aces. That's just her.

“So I don't think there is something new. Maybe she's playing home, so she's a little bit more pumped and not giving those extra few points which she can really give sometime. But that's it.”

Prior to their quarterfinal clash, Pliskova suggested Vandeweghe’s commitment to playing grip-and-rip tennis—even when missing by big margins—is a major difference between the two.

“Like with the game, like, we both have the plan to play aggressive, but I think she's a little bit—not messy sometimes, but she's just going for her shots,” Pliskova said. “Even if she just miss like five meters out, she doesn't care, so it's different. It's not my game style.”
