NEW YORK (AP) — Yet to be challenged even a tiny bit at this U.S. Open, Serena Williams now gets a sure-to-be-hyped match against one of only three women to beat her all year, Sloane Stephens.
From the moment the women's draw came out at Flushing Meadows, it was clear which potential fourth-rounder was the most intriguing: defending champion Williams against up-and-coming talent Stephens, the top two Americans in the rankings.
"As I always say," Stephens said, "I think it will be epic."
And that statement came hours before Williams even had advanced out of the third round by beating 78th-ranked Yaroslava Shvedova of Kazakhstan 6-3, 6-1 in a match that wrapped up at 1:05 a.m. Saturday.
"I'm so excited you guys stayed out for the late-night rendezvous. Thank you, guys, for staying," Williams told the Arthur Ashe Stadium crowd. "I don't think I've ever played this late."
She has dropped a total of eight games through six sets this week. After killing time before facing Shvedova by watching "I Love Lucy" on a computer tablet, Williams produced a 22-3 edge in winners. She faced only one break point, erasing it with one of her six aces, then following up with another at 119 mph.
As for facing Stephens on Sunday, Williams said: "I definitely look forward to it. Whatever happens ... an American for sure will be in the quarterfinals, which is really good."
Much, much earlier, on a ho-hum afternoon devoid of any truly significant surprises, Stephens reached the round of 16 in New York for the first time by beating 23rd-seeded Jamie Hampton 6-1, 6-3 on Friday.
"Serena is the No. 1 player in the world. She's possibly the greatest player of all time. Sloane is Sloane. You know, she's making her own name. She's top 20 in the world for a reason," Hampton said. "They're both great players, both great competitors."
Hampton's blase summation of a Williams-Stephens matchup: "I don't really make too much of it."
She might be the only one.
"It's something," Stephens said, "I think everyone is looking forward to."
And why not? Williams is 31, seeded No. 1, and owns 16 major titles. Stephens is 20, seeded 15th, and already carrying the label of "Next Big Thing" in American tennis. Not only that, but Stephens surprisingly won their Australian Open quarterfinal, one of only four losses in 67 matches for Williams in 2013 (Victoria Azarenka beat her twice, and Sabine Lisicki once). Oh, and then there's this: Stephens found herself in a bit of a brouhaha this year over less-than-flattering comments she made to a reporter about Williams.
"That's all old news now, and we've moved on. We're fine, so I think that's all that matters," Stephens said Friday.
Asked about her relationship with Williams, Stephens replied: "Obviously, we're co-workers. We're Fed Cup teammates. But other than that, everything else is private. It's fine."
When a portion of those comments were relayed to Williams, she said: "We're teammates. I mean, I've always really liked Sloane. I have a lot of respect for Sloane. I think she's a great girl. I think she's great for tennis, as well."
They've played twice in the past — both in January, both on hard courts, both in the quarterfinals. Williams won 6-4, 6-3 at the Brisbane International. Three weeks later, Stephens came back for a 3-6, 7-5, 6-4 victory in Melbourne, where Williams was dealing with an ankle injury.
"She's very aggressive. She stays on top you of you. Doesn't give you any room to breathe. She's intense. She knows what she wants to do out there. That's why she's No. 1," Stephens said.
Thinking back to their previous matches, Stephens added: "It was very important for me the first time to just even get out there and be like, 'OK, it's not as scary as I thought it would be.' I think being able to have played her a couple times before, I'm excited to get back out there."
Williams probably is, too, given the way she responds to disappointments such as her Australian Open loss. Since a first-round exit at last year's French Open, Williams has won 94 of 99 matches and earned 13 titles, including at three of the past five Grand Slam tournaments.
As for what happened against Stephens in Australia, Williams said: "You got to ... think about what you can do, how you can be better. I'm sure she takes it as well — how she did, how she can repeat that."
Her match against Shvedova began at nearly midnight because it followed 2001 champion Lleyton Hewitt's stirring 6-4, 5-7, 3-6, 7-6 (2), 6-1 comeback victory over 2009 winner Juan Martin del Potro, which lasted more than four hours.
It was the ninth time in the last 10 years that two previous title winners faced each other in New York; Hewitt was a participant in three of those in the past, going 0-3.
The 32-year-old Australian, a former No. 1 now ranked 66th after a series of injuries, repeatedly scrambled along the baseline to come up with passing winners against the sixth-seeded del Potro.
"I don't know how many years I've got left in me. I keep getting asked the question," said Hewitt, who won Wimbledon in 2002. "I'm just pumped to get out on this court and try to put on a great show."
Earlier, two other U.S. Open winners, defending champion Andy Murray and top-seeded Novak Djokovic, experienced only brief lulls before staying on course for a possible showdown in the semifinals.
About 40 minutes into his match, Djokovic faced two set points, but he erased those thanks to errors by his opponent, and after adjusting to the swirling wind, wound up defeating 87th-ranked Benjamin Becker 7-6 (2), 6-2, 6-2. Murray dropped a set, yelled at himself after some awkward miscues, but finished well, taking the last five games of his 7-5, 6-1, 3-6, 6-1 victory over 81st-ranked Leonardo Mayer of Argentina.
Becker, who beat Andre Agassi at the 2006 U.S. Open in the final match of the American's career, "is a quality opponent, and he should have won the first set," Djokovic acknowledged. "I was fortunate enough to come back and win the first set, and after that, I was much more comfortable on the court."
During the day session, the only seeded man to bow out was No. 17 Kevin Anderson, a 6-2, 6-2, 6-2 loser against 2006 Australian Open finalist Marcos Baghdatis, while all seven women's matches were decided in two sets. Winners included 2011 French Open champion Li Na, 2012 Wimbledon runner-up Agnieszka Radwanska, and 2008 U.S. Open runner-up Jelena Jankovic.
Stephens has reached at least the fourth round at all four Grand Slam tournaments this season, including a semifinal run at the Australian Open and a quarterfinal berth at Wimbledon, losing to the eventual champion in both.
"She shows up to play at the Slams, for sure," Hampton said.
While Stephens' record at major tournaments this season is 15-3, she is only 17-15 at other tournaments, with six losses in the first or second round.
"The Grand Slams — it's just showtime, I guess," Stephens said, shrugging her shoulders. "What can you do?"
