Serena Williams upsets No. 2 seed in Round 2 and advances

Serena Williams' farewell tour is far from over. She stunned the tennis world as she eliminated No. 2 seed Anett Kontaveit in a hard-fought match to advance to Round 3 of the U.S. Open on Friday.

Williams had previously indicated this will be the last tournament of her legendary career. She is certainly making this year's U.S. Open tennis one fans will remember.

On paper, Williams, 40, was undeniably the underdog as she faced the No. 2 seed Anett Kontaveit, 26, of Estonia.

On Wednesday night, Williams demonstrated why she was a 23-time Grand Slam champion and can never be counted out. She hit serves at up to 119 mph, hung in during lengthy exchanges and big baseline swings, and brought her magic when it was needed most.

The first set was hard-fought, ending in a dramatic tiebreaker that Williams won 7-6(4), Sporting News reported. Kontaveit took the second set 2-6. But Williams came on strong in the third set, taking it 6-2.

"It's no rush here [to leave]," Williams said after winning the match. "There's still a little left in me."

On Friday, Williams faces Ajla Tomljanovic, a 29-year-old Croatian-born Australian, who is currently ranked #46 by the Women's Tennis Association (WTA), in a battle to advance to the fourth round.
