Qualifying for the main draw with solid wins over Shelby Rogers and Heather Watson, Swiatek endured a slow start against the experienced Wozniacki, who won the first three games and ultimately raced out to a 5-1 lead, taking the first set on her third opportunity.

Aiming to avoid a defeat similar to one she took against Simona Halep in Paris, the 18-year-old soon turned the tables on the Dane, scoring the first break of the second set. She saved two break points in the following game to maintain her lead, ultimately holding on to level the match.

“It was a really tough match. Actually, at Roland Garros, I had a tough match like this against Halep, and I didn’t handle the pressure well. I just wanted to play better here and play point by point.

“The first set was really tough, and I just needed time to play the points from the right positions. I’m just glad I did it.”

Wozniacki seemed back to her best early in the decider, taking the first three games as she did to start the match. Swiatek nonetheless fought back, rolling through the next three grames to tie things up and soon found her chance in an all-important ninth game.
