Serena Williams advances to next round in U.S. Open, expected to be her last tournament

NEW YORK, N.Y. (CBS 58) -- Serena Williams will play for another day after she upset the second-seeded Annet Kontaveit, 7-6, 2-6, 6-2.

The tennis icon announced earlier this month that she plans to step away from the sport after this year's U.S. Open.

Williams dominated women's tennis for decades - earning 73 singles titles and 23 singles grand slams.

Her incredible career inspired women and people of color across the globe -- and here in southeast Wisconsin.

"She speaks what she wants to speak. Like when she went to the U.S. Open in a catsuit. It's because she wanted to and she felt confident playing in that. I think that was a big inspiration for all of us," said Mishal Malik, junior at Brookfield Central High School.

Williams says it's not a retirement but an evolution. She wants to grow her family and her off the court businesses.
