Serena Williams has been the talk of the sports world

this week as she plays what might be her final tennis tournament.

And story keeps getting better. Tuesday night at the USTA Billie Jean King National Tennis Center in Flushing Meadow, New York

in a packed Arthur Ashe Stadium, Williams, 40, won her second-round match against the tournament’s No. 2 seed, Anett Kontaveit, 7-6, 2-6, 6-2.

“There’s still a little left in me,” Williams said with a smile during her on-court interview.

“This is what I do best. I love a challenge and I’m rising to the challenge.”

The win moves her to the third round Friday against 29-year-old Australian Ajla Tomljanovic.

Among the thousands of adoring fans was none other than Tiger Woods.

“It was a privilege to watch greatness,” he later said on social media.

Williams says she credits Woods as “one of the main reasons” she still plays.
