PRAGUE, Czech Republic
Jelena Ostapenko won a topsy-turvy three-setter to survive a late charge from former Caroline Wozniacki, 5-7, 6-3, 7-6(5) and advance into the quarterfinals of the J&T Banka Prague Open.
"I played here in Prague a lot when I was young," she said after the match. "I have great memories. I even understand a bit Czech, but I can say only a few words. For example, I can say, 'Thank you.'"
