8:44 CET - Daria Kasatkina (25) said she is thankful that Russian tennis players are still able to compete in international tournaments while other sports have banned them due to the war in Ukraine.
Tennis, unlike many other sports, did not introduce a blanket ban on players from Russia and its ally Belarus after the invasion, which Moscow calls a "special military operation".
Some sports have recently begun to readmit Russian and Belarusian athletes following recommendations issued by the International Olympic Committee (IOC) last month.
Wimbledon banned players from the two countries last year but said in March it would accept them as neutral athletes.
"I was really sad to miss Wimbledon last year - of course for a reason, but it still was painful," Kasatkina told reporters after beating Ukraine's Lesia Tsurenko at the Madrid Open.

The pair met twice during last year's clay swing, with Alcaraz beating Zverev in Madrid to win his second ATP Masters 1000 title before Zverev got his revenge in the French Open quarter-finals a few weeks later.
"I really want to play that match. We played a few times, head-to-head he is up," Alcaraz said.
