Aryna Sabalenka

ROME — Aryna Sabalenka showed no ill-effects from her previous marathon match as she eased past Jelena Ostapenko to reach the semifinals of the Italian Open on Wednesday.

The second-seeded Sabalenka needed just 73 minutes to win 6-2, 6-4, setting up match point with an ace and then sealing the result when Ostapenko returned into the net.

Sabalenka, who didn’t allow the ninth-seeded Ostapenko a break opportunity, showed no sign of the back problem which required treatment during Monday’s three-setter against Elina Svitolina that ended well after midnight local time.

The 26-year-old Sabalenka said she didn’t even practice on Tuesday and focused instead on treatment and recovery. And that clearly paid off.

“I would definitely say that it was the best performance of the tournament,” Sabalenka said. “I’m super happy that I was able to play without pain today and hopefully with every day I will feel better and better, and I will recover as good as I can for the next match.”

Sabalenka will next face the winner of the match later Wednesday between Victoria Azarenka and Danielle Collins.

All three top-ranked women are through to the final four in Rome as the other semifinal pits the top-ranked Iga Swiatek against No. 3 Coco Gauff.
