"I'm really happy for Rafa because I can not imagine how tough was the circumstances of everything," Kasatkina said. "I mean, he's saying that can be his last match at Roland-Garros and I cannot imagine how can you go on the match with this feeling. So another time he shows like how strong he is mentally."
Kasatkina was asked if she could choose one part of Rafa to incorporate into her own game, what would it be?
Not surprisingly, she chose the Spaniard's mental toughness.
"It's so typical to say this, because it's so obvious that he's the best fighter in the history of sport maybe," Kasatkina said. "You can have the best backhand, forehand, serve, forever, but if you cannot fight, you can not win. So I think the fighting spirit is the most important."
Act your age, Iga
Poland's Iga Swiatek turned 21 on Monday in Paris, but she's clearly got more important things to worry about than how old she is.
The Polish tour de force is focused on her jaw-dropping winning streak, which hit 33 with her 6-3, 6-2 victory over Jessica Pegula in quarter-final action on Court Philippe-Chatrier on Wednesday.
So we'll excuse her for temporarily forgetting how old she is. If only we all could be so lucky...
