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.

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

Elena Rybakina was praised by her old coach Goran Ivanisevic, with the Croatian stating that she should be winning more Grand Slams in the future. The 26-year-old can only boast one Grand Slam, which she won at Wimbledon in 2022.

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.
