As Marta Kostyuk played on Centre Court at Wimbledon on Wednesday, local time, her compatriots in Ukraine were dealing with another deadly Russian attack on Kyiv.It has been the same for much of Kostyuk's run to the semifinals.On Monday, after Russian missiles struck residential buildings close to where her parents live, she had to block that out to play her fourth-round match at the grand slam tournament.Last week, Russia hammered the Ukrainian capital with an 11-hour drone and missile attack that killed at least 25 people.For Kostyuk, every day is about finding a way to focus on tennis while not shutting her eyes to what is going on at home."It's not easy to disconnect entirely," she said after beating Jasmine Paolini 6-3, 6-2 to reach the last four at Wimbledon for the first time."Then on Monday they ruined like four streets of residential buildings … I just want to go out there and hopefully beat every single Russian I play in the Olympics."There are no Russian singles players left in the Wimbledon tournament.Kostyuk will face Linda Noskova of the Czech Republic on Thursday.In the other semifinal, American Coco Gauff takes on another Czech player, Karolina Muchova.Kostyuk is the second woman from Ukraine to reach the semifinals at Wimbledon after Elina Svitolina in 2019 and 2023.Svitolina lost on both occasions.So what would it mean for Ukraine if Kostyuk becomes the country's first finalist?"I'm hoping," she said, "it would mean a lot."AP
