Tributes have poured in across the sporting world for Serena Williams following her apparent US Open swansong on Friday, though the 23-time grand slam winner has kept the door ajar on a shock return.

The American, widely considered one of the greatest sportspeople of all time, suggested she would step away from top-level tennis following the tournament at Flushing Meadows.

Following a 7-5 6-7 (4-7) 6-1 loss to Australia's Ajla Tomljanovic in the third round, her journey now looks to be over – though the 40-year-old admittted "you never know" when asked about future appearances.

Her likely last dance, however, has prompted an outpouring of glowing tributes from far and wide, with a host of major names paying their respects to an unparalleld career.

15-time major-winning golfer Tiger Woods called her "the greatest on and off the court" while four-time NBA champion LeBron James hailed her as "so dope".

Serena Williams' long and illustrious tennis career looks to have drawn to a close after the American lost to Ajla Tomljanovic at the US Open on Friday. 

Following a long piece in Vogue last month, Williams wrote of her plan to "move in a different direction" after "these next few weeks", suggesting the tournament at Flushing Meadows would be her last outing.

Thanks to her success and brilliance on the court, Williams has become synonymous with tennis and is regarded by many as the greatest the women's sport has ever seen.

At the age of 40, Williams has persisted with tennis far longer than most do, and that is testament to her quality and enduring desire for success.

Though Williams left a glimmer of a chance that she may yet play again, joking that she "always did love Australia", she may well have taken to the court for the last time. Here, Stats Perform takes a look at the key facts, stats and figures of her career; in other words, Serena's remarkable legacy.

Twenty-three… and done?

Of course, the headline fact for Williams' career is her grand slam titles count.

She has won 23, which is more than anyone else in the Open era.

But she still had one target left: matching Margaret Court. The Australian's 24 grand slam successes include nine won before the Open era began in 1968, though her overall total has been the benchmark ever since she claimed her final crown at the US Open in 1975.

Clearly, victory for Williams at Flushing Meadows would have been the perfect farewell, but it was not to be. Will that near-miss encourage her to take one more shot in Court's homeland next year?

The finals hurdle

Had Williams managed to reach the championship match in Queens, she would have equalled another record.

She headed into the US Open having played in 33 grand slam finals, one more than Martina Navratilova.

But Chris Evert (34) sits out in front, and that record is now set to remain hers for many, many years.

Top of the pile

It's been a while now since Williams was last the highest-ranked player in the world, but in a way that only further highlights how remarkable her career has been.

She's spent 319 weeks ranked as world number one, which is behind only Steffi Graf (377) and Navratilova (332).

While many might have expected Williams to have been top of the pile for even longer, it's worth remembering how she's spent time out due to injuries and pregnancy, with her general involvement in top-level tennis decreasing after 2014 when she played 16 tournaments – in 2016 that halved to eight, and during no year since has she played in more.

Additionally, some will also be surprised to learn she actually only finished the year as the top-ranked female player five times. Nevertheless, that's still third to only Graf (eight) and Navratilova (seven).

Go hard or go home

Such has been Williams' quality, she was always considered a threat regardless of the surface – she's won each grand slam at least three times.

But there's no denying she was at her most lethal on hard courts.

She has won 48 WTA Tour-level titles on hard courts, which is 11 more than anyone else (Graf) in the Open era.

Those 48 come from a grand total of 73 across all surfaces, leaving her ranked fifth behind Navratilova (167), Evert (157), Graf (107) and Court (92).

Surface to say…

Williams' comfort on hard courts goes even further than that.

She's won 541 matches on the surface, making her one of just two female players to surpass 500 victories on one specific ground type.

Navratilova (600 on carpet) is the only other player to achieve the feat, with Serena's sister Venus (498 on hard) the closest to the 23-time grand slam champion.

The grass is greener

Despite that unrivalled excellence, hard courts may not be the surface many feel to be most synonymous with Williams, however.

Wimbledon is the tournament that would appear to be her favourite.

She's reached the final at SW19 11 times. Only Navratilova can better that record for the most finals at one tournament – though it's worth saying she contested the WTA Finals and Chicago 14 times each, Eastbourne 13 times and 12 at Wimbledon.

The Los Angeles Dodgers have lost three games in a row for the first time since mid-June after going down 7-1 at home against the San Diego Padres on Friday.

Yu Darvish was spectacular starting on the mound for the visitors, pitching seven scoreless innings while only allowing two hits and two walks to go with nine strikeouts.

While Darvish was taking the Dodgers' offense out of the contest, the Padres' big bats came through with some timely hits, with star Manny Machado's two-run home run breaking the deadlock in the third inning.

Just three batters after Machado in the same inning, it was teammate Brandon Drury's turn to do the damage, connecting on his own two-run shot to double the Padres' lead to 4-0.

With Drury and Todd Grisham on base in the sixth frame, Padres lead-off hitter Jurickson Profar put the game beyond doubt with a three-run home run, before the Dodgers salvaged one consolation run in the ninth frame through a Joey Gallo base hit.

Overall, the Dodgers only registered four hits as a team, with their MVP candidates Mookie Betts and Freddie Freeman combining to go zero-for-six.

Despite their three-game losing streak, the Dodgers are still five-and-a-half games clear for the best record in the majors at 90-41, and they lead the Padres by 17 games in the NL West.

Castillo, Raleigh lead Mariners to convincing win

Luis Castillo held the Cleveland Guardians scoreless through the first six innings as the Seattle Mariners prevailed 6-1 away from home.

Castillo finished with four strikeouts, allowing five hits and one walk, while with the bat it was Cal Raleigh doing the damage.

Raleigh hit a 366-foot solo home run in the third inning, and he topped that in the sixth frame when he blasted a 424-foot, three-run shot over the right-field wall.

AL Rookie of the Year favourite and the recent recipient of a contract worth up to $470million if all its incentives are hit, Julio Rodriguez came around to score two runs, going one-for-five at the plate.

D'Arnaud and the Braves get to Alcantara

It was a rough outing for NL Cy Young Award shoo-in Sandy Alcantara, giving up six runs in five innings as the Atlanta Braves made him look average in an 8-1 win.

Alcantara leads the majors comfortably in innings pitched (190 – 20 more than second-place) and wins-above-replacement, or WAR (6.9 – 1.9 more than second-place), but he had no answer for a switched-on Braves offense.

Travis d'Arnaud had a day to remember, blasting a pair of 400-foot home runs, while rookies Michael Harris II and Vaughan Grissom also went deep.

Adding to the launch party was Austin Riley, who hit his 34th long-ball of the season – the third-most in the majors – and he has the second-most total bases, trailing only New York Yankees superstar Aaron Judge.

World number one Daniil Medvedev was levels above his third-round opponent Yibing Wu on Friday, defeating him 6-4 6-2 6-2 to set up a highly anticipated clash with Nick Kyrgios in his next match.

While Medvedev had the clear power advantage – finishing with 10 more winners and 11 more aces – he also allowed Wu to beat himself, with 18 unforced errors and three winners in the opening set.

Despite his early wastefulness, Wu still created six break point opportunities in the opening set, but could only capitalise on one. It would be his last break of the match as Medvedev tightened the screws down the stretch.

The Russian took the first four matches of the second set to take away any hope Wu had of fighting back into the contest, and in the third set Medvedev's serve really hit top gear.

He faced no break point opportunities in the final frame as he converted over 70 per cent of his points on both first serves (13-of-18) and second serves (eight-of-11), while Wu's errors returned, with 15 and just four winners.

Against Kyrgios next, Medvedev will be looking for his second win against the Australian in their fifth meeting. In their two matches this year – and their only two since 2019 – Medvedev won in four sets at the Australian Open, before Kyrgios got one back at the Canadian Open.

ACES/DOUBLE FAULTS

Medvedev – 12/5

Wu – 1/0

WINNERS/UNFORCED ERRORS

Medvedev – 26/27

Wu – 16/42

BREAK POINTS WON

Medvedev – 6/12

Wu – 1/8

Nick Kyrgios was far too good J.J. Wolf in the third round of the US Open on Friday, not having his serve broken a single time in the 6-4 6-2 6-3 victory.

Kyrgios dominated the match with his serve, racking up 21 aces to Wolf's five, and of the seven break point opportunities the Australian allowed, he saved all seven.

His return game was sharp as well, creating 11 break points and converting five, and he used it to break away in the second set, rattling off five consecutive games to comfortably go up two sets to love.

The third set was more competitive as Kyrgios had a pair of double faults, and more unforced errors (17) than winners (16), but he ultimately had too much firepower for the 23-year-old American.

After coming back from a love-40 deficit, saving four break points in the game, Kyrgios put the finishing touches on the straight sets win with another break of serve to seal it.

With the win, he books his spot in the fourth round, where he will meet world number one Daniil Medvedev.

Kyrgios has won three of the four career meetings between the pair, including their most recent fixture at the Canadian Open.

ACES/DOUBLE FAULTS

Kyrgios – 21/5

Wolf – 6/1

WINNERS/UNFORCED ERRORS

Kyrgios – 36/32

Wolf – 20/26

BREAK POINTS WON

Kyrgios – 5/11

Wolf – 0/7

Serena Williams hinted that she will return to the court at some point in the future after going down in the third round of the US Open against Ajla Tomljanovic on Friday.

Williams, who saved five match points before eventually succumbing in the three-plus hour marathon, gave an emotional on-court interview where she thanked her family, but also highlighted that she felt like she was getting better as the tournament wore on.

When asked conclusively if this was her final US Open, she was non-committal, saying "you never know".

She took the insinuation that she is not finished playing a step further during her sit-down press conference, laying the breadcrumbs for another go around at the Australian Open.

"I don't know [what it would take to play again] – I'm not thinking about that. I always did love Australia, though," she said with a smile.

"But yeah, you know what, I've come a long way since last year at Wimbledon. Just not sure if that was my last moment or not. Making it a different moment I think is much better.

"And it takes a lot of work to get here. Clearly I'm still capable. It takes a lot more than that. 

"I'm ready to, like, be a mom, explore a different version of Serena. Technically in the world I'm still super young, so I want to have a little bit of a life while I'm still walking."

When asked what she thinks her life will be like moving forward, Williams said she is excited to be able to spend more time with her daughter, and that karaoke is on the agenda.

"I'm definitely resting tomorrow, and then probably spending some time with my daughter," she said. "I'm a super hands-on mom. I've been with her almost every single day of her life, minus two days or three days.

"It's been really hard on her, my career. So it will be, you know, nice just to do that and spend some time with her, do things that I never really have done or had an opportunity to do. I have such a bright future ahead of me, I don't know.

"Also, I'm kind of at an advantage because COVID happened. I think everyone shut down for a year, and we kind of got to see what our lives would be like if we weren't playing tennis. 

"Then I got injured last year, so I took off literally a year. So I got to see, again, like, what every day would be like to wake up and not have to go to the gym.

"So I don't know. I think I'm definitely probably going to be karaoke-ing tomorrow."

Touching on how she would like her career to be remembered, Williams said her unique passion and fire is at the forefront.

"I mean, there's so many things to be remembered by," she said. "Like the fight. I'm such a fighter. 

"I feel like I really brought something, and bring something, to tennis. The different looks, the fist pumps, the just crazy intensity. I think that obviously the passion, I think, is a really good word.

"Just continuing through ups and downs. I could go on and on. But I just honestly am so grateful that I had this moment, and that I'm Serena."

Serena Williams was emotional during her post-match interview in the sold-out Arthur Ashe Stadium after her loss to Ajla Tomljanovic in the third round, thanking her family for their decades of support.

Williams ended up going down in a match that lasted three hours and seven minutes, with a 15-minute final game where Williams saved five match points illustrating her fighting spirit down to the last moments.

If this is her final US Open – which she was hesitant to confirm – she will finish with the most main draw wins ever at the tournament with 108, and her 23 grand slam titles are also the most of all-time.

Speaking on the court after Tomljanovic gladly ceded the floor to the legend, Williams turned her attention immediately to her family as she reflected on the journey to this point.

"Thank you, Daddy. I know you're watching," she said as she began to tear up. "Thanks, Mom… I thank everyone that's here, that's been on my side so many years, decades. Oh, my gosh, literally decades.

"But it all started with my parents – they deserve everything. So I'm really grateful for them. These are happy tears, I guess. I don't know.

"And I wouldn't be Serena if there wasn't Venus, so thank you, Venus. She's the only reason that Serena Williams ever existed."

She added: "It's been a fun ride. It's been the most incredible ride and journey I've ever been on, I mean, in my life.

"I'm just so grateful to every single person that's ever said 'go, Serena' in their life. I'm just so grateful."

When asked if this would definitely be her last US Open, Williams was hesitant due to how well she performed, and left the question unanswered.

"I mean, I'm literally playing my way into this and getting better – I should have started sooner this year," she said with a laugh.

"I don't think so, but you never know. I don't know."

In a game with NBA talent on both sides, Giannis Antetokounmpo willed Greece to a 89-85 win against Croatia in Friday's Eurobasket action.

Antetokounmpo was the game's equal top-scorer with 27 points, shooting nine-of-24 from the field and nine-of-11 from the free throw line while adding 11 rebounds, six assists and three blocks.

He was supported well by teammate Tyler Dorsey, who was incredibly efficient for his 27 points, finishing nine-of-17 from the field, including going five-of-nine from beyond the arc, and he added five rebounds and two steals.

For Croatia, Utah Jazz wing Bojan Bogdanovic eight-of-15 from the field to score 19 points with seven rebounds, Los Angeles Clippers centre Ivica Zubac had 11 points and five rebounds with two blocks, and former top-five NBA Draft pick Mario Hezonja chipped in 10 points and eight rebounds.

Also on Friday, reigning back-to-back NBA MVP Nikola Jokic put up 22 points, six rebounds and four assists to help Serbia comfortably handle the Netherlands 100-76.

He dominated the outing along with Euroleague star Vasilje Micic, who posted 22 points and 12 assists.

In a terrific contest, recent Washington Wizards lottery pick Deni Avdija led his team to a 89-87 win over Cleveland Cavaliers forward Lauri Markkanen's Finland.

Avdija had 23 points and 15 rebounds, while Markkanen top-scored with 33 points and 12 rebounds, aided by a 14-of-15 performance at the free throw line.

Big new signings hit the ground running in the first round of LIV Golf Boston, but after 18 holes at The International Golf Club it is Matthew Wolff and Talor Gooch tied for the lead at seven under.

While Gooch got to his 63 in a traditional fashion, posting eight birdies and one bogey, Wolff had far more ups and downs, making up for his three bogeys with six birdies, an eagle and a hole-in-one – the first ace in LIV Golf history.

One stroke behind the leaders are new arrivals Cameron Smith and Joaquin Neimann, after both played in last week's PGA Tour Championship.

Smith had five birdies and two eagles, showing off his firepower, but a double-bogey on the par-four 14th hole cost him a chance at the first-round lead.

After his round, Smith called it "great fun" and said "it was nice to see a familiar face" about his pairing with Dustin Johnson.

The rest of the field is at least two further strokes back, with Kevin Na, Bernd Wiesberger, Louis Oosthuizen, Paul Casey and Anirban Lahiri occupying the tie for fifth at four under.

The logjam at three under includes Dustin Johnson and Pat Perez, who along with Gooch and Patrick Reed (one under) have their Four Aces GC sitting second in the team standings. They trail only Hy Flyers GC, consisting of Wolff, Wiesberger, Cameron Tringale (one over) and Phil Mickelson (four over, 45th out of 48).

Bryson DeChambeau and Carlos Ortiz are at one under, and the Koepka brothers – Brooks and Chase – shot even-par 70s.

Coco Gauff admitted it would be a "lifelong dream" to face Serena Williams at the US Open, in what is likely to be the latter's final tournament of a glittering career.

Gauff reached the second week at Flushing Meadows in the women's singles for the first time after cruising to a 6-2-6-3 win over Madison Keys on Friday.

The number 12 seed saw off her fellow American in composed fashion to book her place in the last 16, exceeding her previous best result at the US Open in 2019.

Gauff was largely in control against the number 20 seed Keys to deliver near-flawless performance, chasing a second grand slam final of the year after finishing as runner-up at the French Open to Iga Swiatek.

She will face China's Zhang Shuai in the next round, but when asked if she will watch Williams' match against Ajla Tomljanovic later in the day during her on-court interview, Gauff said she would, adding: "It's been amazing watching Serena's matches so far. I don't know when I'd be due to face her but that's the goal.

"It's been a lifelong dream of mine to do that. Five years ago yesterday I was watching Venus and Serena play here. It's crazy to be on this court now.

"I tried to flex to my friends that I had courtside seats, now I'm on the court!"

Should both remain in the tournament, Gauff and Williams would face each other in the semi-finals.

Gauff also paid tribute to Keys, and to the crowd at Arthur Ashe Stadium, saying: "[The win] means a lot to me... I missed my alarm and was so late. I was here until 9pm last night and lost a doubles match [with Jessica Pegula].

"Kudos to my team, they got me up for it.

"I wasn't sure how the crowd was going to go. We all love Madison... I'm good friends with her off the court, but having support here meant a lot."
