Canadian teenager Bianca Andreescu showed that she intends to be a formidable force in the women's game with a 6-4 6-4 win over former world number one Caroline Wozniacki in the third round of the U.S. Open on Saturday. Andreescu's in-your-face style of tennis overwhelmed the Dane on a warm and sunny day on Arthur Ashe Stadium as she reached the last 16 on her U.S. Open debut. Next up for the 19-year-old Indian Wells and Rogers Cup champion is a meeting with American Taylor Townsend, who defeated Sorana Cirstea. Andreescu said she has never played anyone who comes to the net on virtually every point like 23-year-old Townsend but is ready to put in the work ahead of their Monday clash. "Well, there aren't a lot of players that play like her, so I'm going to do my best to figure out what to do when she comes to the net," said Andreescu. "Like I said, I'm going to work on my passing shots tomorrow and stay as aggressive as I can." Anett Kontaveit conceded her third round game against Belinda Bencic due to illness. Kristie Ahn defeated Jelena Ostapenko with a 6-3 7-5 victory. Julia Georges beat Kiki Bertens in straight set in a 6-2, 6-3 upset. Belgium's Elise Mertens defeated Andrea Petkovic in straight sets to qualify for the second week.
