Following a slow start, Radwanska found her range to prevail, 7-5, 6-3, in a topsy-turvy encounter and set up a semifinal against World No.1 Angelique Kerber.

“She definitely served brutal today. All I could do was just wait for the break point,” Radwanska told on-court interviewer Andrew Krasny afterwards. “A very tight match and I’m just happy I could do my best at the important moments.

“You’re just waiting and praying that the first serve is not going to be in. She’s definitely one of the best or even the best server on tour and every break matters.”

Radwanska went into the contest having never lost a set to Pliskova in six previous meetings. However, it was the Czech that made the early running, surging into a 4-2 lead and holding a point for an insurance break, only to fire fractionally wide.

The next game, demons of past encounters came back to haunt her, an errant forehand presenting the Pole with the chance to draw level. She gratefully accepted, springing up to punch an inviting second serve down the line. Soon afterwards her comeback was complete, the No.2 seed producing another pin-point return to wrap up the set.

These momentum shifts continued into the second, Pliskova pegging back an early Radwanska surge. At 3-3, she had the opportunity to consolidate her dominance only for the Pole to stave off the threat of a break with some cat-like reflexes at the net.

This proved to be Pliskova’s last stand, an errant smash the following game giving Radwanska the opportunity to serve for the match. It was a gift she gratefully accepted, setting up a Saturday showdown with Kerber.

“It’s the semis so I really have nothing to lose, especially as I’m going to play the best player of this season,” Radwanska added. “She’s been playing amazing tennis all year, on every surface. Hopefully I can play even better than today.”
