Chakvetadze, a former world No. 8, appeared on a podcast with former three-time Grand Slam finalist Safina. At one point during their conversation, the former Russian tennis star said that Ivanisevic privately told her he was surprised that Rybakina only had one Wimbledon title in her collection.

Iga Swiatek outplayed Anna Kalinskaya to reach her third Cincinnati semifinal, where Elena Rybakina -- fresh off a straight-sets win over Aryna Sabalenka -- awaits.

In her four matches, Paolini has beaten two Grand Slam champions, Gauff and Barbora Krejcikova. Kudermetova hasn’t faced anyone with that kind of pedigree, but as an unseeded player, she has played one more round, and she has survived two close matches with quality opponents, Clara Tauson and Belinda Bencic.

But Vukov refused to sit silently - and after appealing the WTA's ban - he won his case and rejoined Rybakina's team at the Cincinnati Open. And that is already having a positive impact on the Kazakh, who is through to the semifinal after ousting top seed Aryna Sabalenka 6-1 6-4.

Stefano Vukov, formerly banned coach of WTA World No. 10 Elena Rybakina, was seen sitting in the 2022 Wimbledon champion's box in Cincinnati just a day after the WTA lifted his suspension.

The Cincinnati Open is starting to heat up on the tour. With the quarterfinal matches on the cards, players will be hoping to enter the final four this week.
