Grand Slam winner, Serena Williams takes centre stage on Sunday as she aims to make the quarter-finals of the US Open.
Six-time champion Williams, 36, faces Estonian Kaia Kanepi, who knocked out world number one Simona Halep and has yet to drop a set at the tournament.
Serena beat her sister Venus in their 30th professional match to reach the fourth round of the U.S. Open.
"I beat Halep, so I should be able to beat all the others as well," Kanepi said of raised expectations of her.

Serena on Friday night, beat her elder her with a 6-1, 6-2 rout in the third round of the US Open.
She shook off an early ankle injury to win seven straight games and seize control in perhaps her most dominant performance since giving birth to her daughter a year ago Saturday.

The sisters' earliest meeting in a Grand Slam tournament in 20 years was over early, with Venus unable to do anything to blunt Serena's power, even after the fans who were part of Friday's single-day-record crowd of 70,162 tried desperately to get behind her with pleas of "Come on, Venus!" early in the second set.
"I think it's by far the best match I ever played against her in forever," Serena said of the match, which lasted 1 hour, 12 minutes. "But I don't know about ever, ever. It probably was. I played much better tonight than I have since I started this journey on my way back."
Sloane Stephens also matched on into the quarter-finals after beating former No. 1, Victoria Azarenka in a tough third round game on Friday evening.
Stephens, the defending champion and No. 3 seed, grabbed the last three games after returning from a brief break while the Arthur Ashe Stadium's roof was shut Friday and pulled out a 6-3, 6-4 victory over two-time runner-up Azarenka to reach the fourth round.
