What a first week of the NFL season that was.

So much drama, so many late twists, and it's almost time to do it all over again as Week 2 looms on the horizon.

Sunday sees Tom Brady and the Tampa Bay Buccaneers looking to follow up their opening win against the Dallas Cowboys when they head to New Orleans, the Los Angeles Rams will aim to get on the board when they host the Atlanta Falcons, while Russell Wilson's first home game for the Denver Broncos sees them welcome the Houston Texans.

With all that and more, Stats Perform has used Opta data to preview the weekend's action in the NFL.

Tampa Bay Buccaneers (1-0) @ New Orleans Saints (1-0)

The Saints have won their last seven regular-season games against the Buccaneers, matching the longest previous winning streak by either team in this rivalry, a run of seven consecutive wins by New Orleans from 2011 to 2014. Tampa Bay did beat the Saints in a Divisional Playoff game following the 2020 season.

Tampa Bay had one interception (by Antoine Winfield Junior) in their season-opening win at Dallas. The Bucs were 11-0 last season in games in which they intercepted at least one pass. The Green Bay Packers (also 11-0) were the only other NFL team to go unbeaten last season in games in which they recorded one or more interceptions.

New Orleans won their season opener in Atlanta, 27-26, after trailing 26-10 in the fourth quarter. It was the first time in franchise history that the Saints won a game in which they trailed by 16 or more points in the fourth quarter, and only the third time they won a game in which they were behind by 16 or more points in the second half.

Tom Brady and the Bucs lost their last game against the Saints, 9-0 (Week 15 last season). That is one of only three times that Brady's team has been shut out in his 317 regular-season and 47 postseason starts in the NFL. The other shutouts were in 2003 (Patriots at Buffalo, 31-0 in Week 1) and 2014 (Patriots at Miami, 21-0 in Week 14).

Atlanta Falcons (0-1) @ Los Angeles Rams (0-1)

Including their original stint in California and time in St. Louis, the Rams are 28-8-2 (.778) at home against their former NFC West rival, Atlanta Falcons. That is the best home record of any franchise against a single opponent (minimum of 30 games) in NFL history.

Cordarrelle Patterson rushed for 120 yards and a touchdown in Atlanta's season opener. At 31 years old, Patterson is the second-oldest player in team history to have 100+ rushing yards and a touchdown run in a game, behind only Warrick Dunn, who had two such games.

The Rams started the season with a 31-10 loss to the Bills, the largest home loss in a season opener ever by a defending Super Bowl champion. The team has not started a season at 0-2 since 2011 when they were in St. Louis and have not lost their first two games as the Los Angeles Rams since 1987.

Cooper Kupp tied a career high with 13 catches in the opener against Buffalo. Including playoffs, Kupp has at least five receptions in each of the Rams' last 22 games. Only Antonio Brown has a longer such streak of team games with five or more catches in the Super Bowl era (37).

Houston Texans (0-0-1) @ Denver Broncos (0-1)

The Texans opened their season with a 20-20 tie against the Indianapolis Colts, despite being outgained by 218 yards in the game. Prior to Houston on Sunday, the last team to tie a game while having 200+ yards less than their opponent was the Packers against the Broncos in 1987.

In his first game with the Texans, O.J. Howard scored touchdowns on each of his two receptions. Howard joins Jaelen Strong as the only players to ever have two TD catches in their team debut for Houston.

Denver committed 12 penalties in their 17-16 loss to the Seahawks on Monday. It was the most penalties the Broncos have ever committed in a season opener, surpassing the 11 penalties they had to kick off the 1970 season against the Bills.

Russell Wilson threw for 340 yards against the Seahawks in his Denver debut. It was the most passing yards by a Broncos QB on their debut with the team and Wilson's 12th career game with 340+ passing yards (his teams are 5-7 in those games).

Elsewhere...

The New England Patriots travel to the Pittsburgh Steelers after suffering a 20-7 loss to the Miami Dolphins in Week 1, and have not started a season with consecutive double-digit losses since losing three straight games by such a margin to begin the 1969 campaign.

Baltimore's Lamar Jackson threw for three touchdowns against the New York Jets after throwing three or more TDs just twice all of last season. Before they host the Dolphins, it is notable that, in his career, the Ravens are 13-1 when Jackson has three or more pass TDs, the second-best team record among active players behind Josh Allen at 14-1 (minimum 10 such games).

Starting with their 2013 NFC Championship game success over the 49ers, the Seattle Seahawks are 15-2 in their last 17 games against San Francisco, which includes season sweeps in 2020 and 2021. The 15 wins since January 2014 are tied with the Patriots (vs. Jets) for the most by an NFL team against a single opponent in that span (including playoffs).

The Arizona Cardinals will need to watch Davante Adams, who had 10 catches for 141 yards on 17 targets in his Las Vegas Raiders debut. That is the most targets for any player in their first career game with the Raiders in the past 30 seasons. The only other with player with 15+ targets in their Raiders debut over that span is Randy Moss in 2005 (15).

Anthony Joshua believes a bout with Tyson Fury in December is his "only chance" to face off against the Gypsy King, promoter Eddie Hearn has said.

Fury has offered terms to his compatriot for a bout in December, with the WBC belt on the line, for a fight long hailed as the 'Battle of Britain'.

A bout has been a long time coming, with an agreement in place for the pair to fight in Saudi Arabia last year before a court ordered Fury to honour his rematch with Deontay Wilder, who he subsequently beat in Las Vegas.

However, hopes of a unified clash with Joshua were ended by AJ's defeat to Oleksandr Usyk at the Tottenham Hotspur Stadium, who then won the rematch with his fellow 2012 Olympic gold medallist last month.

That appeared to spell an end for Joshua at the summit of the heavyweight game, at least temporarily, but Fury has moved swiftly to offer an opportunity to his rival – with Hearn explaining Joshua's thinking is that this is his only shot.

"He thinks: this is my only chance, because if he fights Usyk, win or lose I think he'll retire or you never know with Fury, he could just never fight again," he told Sky Sports.

"The reason he accepts these terms is he feels this is the only chance he'll get to fight Tyson Fury. So, therefore, okay, it would have been better to come off a victory but we're here and [Joshua thinks] I can beat him and I feel good.

"When he drew to [Deontay] Wilder, we offered Fury the fight against AJ and we offered him 60-40 and he said no and he said I'll only take 50-50.

"That's one of the reasons I wanted to push back on some of the terms. But in the end it was AJ who overruled and said no just accept it. He's always believed he can beat him."

The next step to scheduling the fight is the signing of the contracts and, while Hearn perceives no issues with that, he is still wary as to whether Fury is genuine.

"Broadcasters need to have their discussions. Which I don't think will be a problem. It's actually not that complicated," he added.

"If they're genuine and George  [Warren] tells me they are, then I think the fight will get made. I think George feels his instructions are to make the fight. But you just never know with Tyson Fury. Is this a ploy to speed up the Usyk fight, get more money from a site?

"It might have been a bluff, or a bit of publicity that actually turns into it happening. Or maybe it was genuine from the start. It could be anything. That's a sceptical view but right now I'm going along the lines of I believe him because I want to be positive and work together to make it happen."

Whether or not it is Fury that Joshua faces off against, Hearn has made it clear AJ will return to the ring before the end of the year.

"We've been looking at opponents for AJ for December and his list is very different to my list. So I don't think he's interested in opponents that he's just going to get no credit or respect for. Straight away when I asked him about this fight, he went, 'Let's do it'," he explained.

"He hasn't got any major injuries or anything like that. They want to do it. I think he's coming off a decent performance," the promoter added. "He just fancies the fight and fancies his chances. He's willing to roll the dice."

Saul 'Canelo' Alvarez declared his mission for Saturday's trilogy fight with bitter rival Gennady Golovkin is to "finish him off" inside the distance.

After a split draw in their first fight five years ago, Canelo was declared the winner of their September 2018 rematch by a majority decision.

He edged a tight contest 115-113 on two of the judges' cards, with the other judge unable to split the fighters, while many observers thought Golovkin had been the superior fighter.

It means there is unfinished business heading into the long-awaited third fight, which, like the first two, will play out at T-Mobile Arena in Las Vegas.

Golovkin, now 40 years of age, is a big underdog this time, while 32-year-old Canelo must handle the pressure of being the man expected to reign in the ring.

Speaking to Stats Perform, Canelo said: "I feel great, I'm ready for this weekend, so I can't wait. I'm very excited.

"I was very happy when I won the second fight because I knew I won the first fight, too, so I was really happy."

There is a real dislike between the fighters on a personal basis, with Mexican Canelo open about his disdain for Kazakh Golovkin.

"As a fighter, he's a great fighter, but as a person I don't like him," Canelo said.

The boxing website Boxrec rates Canelo as the pound-for-pound best fighter on the planet, placing Golovkin ninth on that list.

Nothing would give Canelo more pleasure than being able to settle fight three against 'Triple G' without the need for judges this time.

By channelling his personal feelings towards Golovkin into his punching, Canelo is confident of getting the job done.

"It gives you that extra motivation of wanting to win, to go and finish him off basically," Canelo said. "That's what I've been training for and that's what I'm hoping to do on Saturday."

Golovkin carries a 42-1-1 pro career record into the fight, while Canelo is 57-2-2 after slipping up in a light-heavyweight clash with Dmitry Bivol in May, also at T-Mobile Arena.

He narrowly lost on points to his Russian opponent that day, after going up a weight, and is adamant the recent experience of defeat will not hinder him come bell time on Saturday.

"It gives me extra motivation to come back," Canelo said. "Sometimes in boxing you win or lose, but I'm going to come back stronger than ever.

"I did something that I didn't need to do, going up a division, I have no right to go up there, but that's what happens. I lost this, and I need to accept it like a man and come back stronger than ever, and that's what I'll be doing."

Bryson DeChambeau insists he harbours no regrets following his decision to join the controversial LIV Golf Invitational Series.

The 2020 U.S. Open winner became one of the biggest names to join the lucrative Saudi-backed tour in June, later describing his move as "a business decision".

Despite LIV Golf players becoming the targets of hostility when playing at majors and selected events on other tours in recent weeks, DeChambeau remains content with his choice.

"This is the biggest decision, besides choosing my agent, that I've ever made in my entire life," DeChambeau said, ahead of LIV Golf Chicago. 

"I couldn't be more happy to be over here, I have no buyer's remorse. 

"I have ultimate respect for the PGA Tour and what they've done for my career, as I've said from day one. They've allowed me this opportunity." 

While the PGA Tour has reacted furiously to the founding of the new circuit, DeChambeau said in August he was "not worried" by their blanket ban on LIV Golf players, adding: "I think it will get figured out."

The 29-year-old reiterated that belief this week, saying: "I personally believe that over the course of time they will come to a resolution. There has to be, it's only in the best interests of golf down the road.

"What LIV Golf has provided is something new and unique, different. With that being said, there is going to some disruption and people aren't going to like it. 

"I respect every single person who thinks it isn't good for the game of golf, I understand it. But I hope they are open-minded enough to go, 'you know what? I'll give this a chance'. If you give it a chance, you might just see something pretty cool.

"I'm a golf fan, first and foremost. I'm going to watch golf wherever it's played with some of the best players in the world, whoever it is. I think down the road that'll change. 

"I think that this [LIV Golf] will become something special, even more special than what it is now, and moving forward in the future, I'll still watch other tournaments that I've won and done well at before."

The subject of LIV Golf players appearing at team events such as the Ryder Cup has been fiercely debated since the split, with Rory McIlroy adamant this week none of the circuit's players should be able to feature. 

But DeChambeau, who has helped the United States to two victories at the Ryder Cup (2018 and 2021) and one at the Presidents Cup (2019), believes a ban would only serve to harm the tournaments.

"I personally think that the team events are only hurting themselves by not allowing us to play," he added. "Not allowing us to qualify through some capacity, in some facet."

Phoenix Suns vice-chairman Jahm Najafi has called for Robert Sarver's resignation after the majority owner was found to have engaged in racist and sexist conduct at the workplace.

The NBA hit Sarver with a one-year suspension and a $10million fine this week, having interviewed 320 people after allegations emerged of inappropriate behaviour during his 18 years with the Suns.

The league stopped short of issuing a lifetime ban, however, leading four-time MVP LeBron James to declare: "Our league definitely got this wrong."

NBA commissioner Adam Silver said Sarver was "on notice" in the aftermath of the ruling, but Najafi does not wish to see Sarver stay on.

In an open letter to the Suns players and staff, Najafi said he had no interest in becoming the next managing partner, but would "work tirelessly to ensure the next team steward treats all stakeholders with dignity, professionalism and respect".

"Due to the NBA's investigation and findings, I have no choice but to speak up on behalf of the hundreds of you that have been impacted by your interactions with Robert Sarver," the letter from Najafi read.

"There should be zero tolerance for discriminatory actions of any level, in any setting, let alone a professional one.

"There is no question that the findings determined that Mr Sarver's lewd, misogynistic and racist conduct had a substantial negative impact on you and has no place in our society.

"Similar conduct by any CEO, executive director, president, teacher, coach or any other position of leadership would warrant immediate termination. The fact that Robert Sarver 'owns' the team does not give him a licence to treat others differently than any other leader.

"The fact anyone would find him fit to lead because of this 'ownership' position is forgetting that NBA teams belong to the communities they serve. Team investors are merely temporary stewards.

"If we, as sports leaders, are not held to the same standards, then how can we expect a functional society with integrity and respect on any level?

"I cannot in good judgement sit back and allow our children and future generations of fans to think that this behaviour is tolerated because of wealth and privilege.

"Therefore, in accordance with my commitment to helping eradicate any form of racism, sexism and bias, as vice-chairman of the Phoenix Suns, I am calling for the resignation of Robert Sarver."

Najafi has been critical of Sarver since the allegations were first reported last November, and is one of three vice-chairmen at Phoenix, where several other minority investors form part of the ownership group.

For the third, and presumably, the last time, Saul 'Canelo' Alvarez and Gennady Golovkin will share a ring on Saturday as they fight it out for super-middleweight glory in Las Vegas.

The trilogy tussle at the T-Mobile Arena has a lot to live up to after the previous battles between the pair, in 2017 and 2018.

Alvarez goes into this one as the firm favourite, with few giving the 40-year-old Golovkin much hope, but the tight nature of their previous fights could stir something in the Kazakh.

Ahead of the keenly anticipated showdown, Stats Perform has looked at the state of play in one of boxing's greatest modern-day rivalries.

The trilogy so far

If history is a guide, nobody should be surprised if fight three between these warriors goes the distance.

Both previous clashes, which were contested at middleweight, went all the way. The first ended in a split-decision draw, and the second went down as an Alvarez points win, albeit one that many called into question. Two of three judges gave him the win by a sliver, the other scoring it a draw.

So expect a sense of deja vu this weekend, not least because the fight is being held at the same venue that put on their first two clashes.

Alvarez was given a bizarrely lopsided 118-110 victory by one of the first fight's judges, while another scored it narrowly in Golovkin's favour, and the third as a draw, so perhaps this time the fighters will be eager to avoid any possible lottery on the scorecards.

A victory inside the distance for either man might be the most fitting way of bringing their rivalry to its conclusion.

What's happened since the rematch?

There was inevitably talk of a trilogy fight after Canelo got the better of Golovkin four years ago, but it took until May of this year for confirmation to come through.

Canelo has danced between the divisions, winning title fights at middleweight, super-middleweight and light heavyweight since he last encountered Golovkin in the ring.

Golovkin has fought just four times, and will hope that is sufficient preparation.

Unlike Canelo, he has a 100 per cent record from his fights in the last four years. Canelo was beaten on his last outing, losing to Dmitry Bivol on a unanimous, albeit tight verdict (115-113 with all three judges), when contesting the WBA light heavyweight belt.

Has anything changed in four years?

Ask yourself the same question. Of course, things change. We get older; past a certain point, perhaps we slow down a little; the pandemic put the brakes on most aspects of our lives, for a while at least.

It took a heavy toll on boxing, too, but Canelo and Golovkin have got the buzz back, and one thing that has not changed appears to be the enmity between them.

As Eddie Hearn, chairman of Matchroom Boxing, said on announcing the fight: "These are two men that bitterly dislike each other and want to end this incredible series with a blistering KO."

Canelo is still a young man, at 32, and he carries a 57-2-2 record into the fight, putting his WBA, WBC, IBF and WBO belts on the line.

Golovkin boasts a 42-1-1 career as he steps up to super-middleweight for the first time, but he is very much the veteran, the man that time is most likely to have caught up on since part two of this series.

According to Canelo, Golovkin has been taking on third-rate opponents to extend his career for this payday.

"A knockout, that's what I see," said a confident Canelo in June.

Some juicy shots are being thrown outside the ring, boiling up nicely for ring time.

Patrick Mahomes just about got the better of Justin Herbert on Thursday but expects the Los Angeles Chargers to continue to push his Kansas City Chiefs all the way.

Both the Chiefs and the Chargers are tipped for Super Bowl contention this year in a highly talented AFC West.

Kansas City have won the division six years in a row, but the scale of their task this season was made clear in this meeting with the Chargers, who forced Mahomes to rally from a 17-7 deficit to win 27-24.

Herbert admirably battled a rib injury as he attempted to take down Mahomes, yet the former MVP delivered yet another comeback.

This was the 20th game of Mahomes' career – regular season or playoffs – in which he had been down by 10 points, and he has now converted 11 of those into wins.

Past turnarounds include the Super Bowl LIV success against the San Francisco 49ers when the Chiefs scored 21 unanswered points in the fourth quarter, as well as Herbert's NFL debut, when the Chargers lost in overtime early in the 2020 season.

"I think every game [against Herbert] is going to be a lot like this one," Mahomes told Amazon Prime Video.

"In the games I've played against him in the past, we've gone to overtime twice and it's been an end-of-game situation.

"It's going to be games like this, and hopefully I can find a ways to win them and our team can find a ways to win them, like we did today."

Mahomes is the only NFL quarterback with a winning record in games where he has trailed by double-digit points (minimum 20 starts), with Tom Brady next-best at 39-61 (.390).

"I want to go out there and win; I don't care how it looks," Mahomes added. "Tonight was very ugly.

"I'm sure it's not going to have a great film session tomorrow, but we found a way to get a win at the end of the day, and that's all I care about."

Los Angeles Chargers head coach Brandon Staley says they will learn more about the severity of quarterback Justin Herbert's apparent ribs injury on Friday but is confident he will be OK.

Herbert played through apparent pain in Thursday's 27-24 loss to the Kansas City Chiefs following a series of big tackles on the QB in the fourth quarter.

The Chargers QB still managed to find DeAndre Carter and then Josh Palmer in an impressive drive for a late touchdown but seemed in discomfort and gestured towards his ribs on the sidelines.

Herbert did not appear for post-game media duties, instead going off for an X-ray on the injury, although Staley was confident he would be fine.

"No," Staley told reporters when asked if he was concerned about Herbert's health. "No, because he's Justin Herbert."

Staley added: "You're not going to see a quarterback at any level of football play tougher and do more for their team and will their team to give them a chance more than him.

"There's nobody that can do what he can do, nobody. He showed a lot of guts, he showed us what he shows every day, that we're never out of the fight, and he brought us back and gave us a chance."

Despite that, Staley revealed they anticipate they will learn more about Herbert's health on Friday after a more thorough evaluation.

The Tampa Bay Rays made MLB history with all nine hitters in their starting line-up being Latin American for the first time in their 11-0 blowout win over the Toronto Blue Jays on Thursday.

The feat occurred on Roberto Clemente Day, the official annual date the MLB holds to coincide with the start of Hispanic Heritage Month. The late Clemente is a Hall of Fame outfielder from Puerto Rico, who was a two-time World Series winner and National League MVP.

The Rays hitters did not let him down either, with Yandy Diaz blasting a three-run homer at the top of the second inning to open up a 4-0 lead. Isaac Paredes launched a solo home run in the seventh inning, while he also had an RBI single.

Rays manager Kevin Cash claimed that he did not realise that he had made history with his side's line-up until halfway through the game.

Meanwhile, the defeat is the Blue Jays' second biggest blowout loss this season, leaving them 81-63 but still well placed in the American League Wild Card race.

Carrasco stars as Mets sink Pirates

Clemente's former side, the Pittsburgh Pirates, were brushed aside 7-1 by the New York Mets, for whom Carlos Carrasco starred.

The Mets 35-year-old right-hander tossed down 11 strikeouts across six innings, allowing only four hits, one earned run and two walks. The win was Carrasco's 15th of the season.

Francisco Lindor crushed a two-run homer into the upper deck for his 24th blast of the season, setting a Mets' single-season record for a short-stop.

Pujols' 700 chase stalls with sac fly

The cameras and phones came out with bases loaded in the ninth inning searching for history, but Albert Pujols could only deliver a sacrifice fly in the St Louis Cardinals' 3-2 loss to the Cincinnati Reds.

Pujols is three runs shy of becoming only the fourth player in majors' history to blast 700 homers, but he could not add to his tally, although his sac fly to right allowed Brendan Donovan to get home to halve the margin in the ninth.

Corey Dickerson ground out to end the game as the Reds snapped their six-game losing run, with solo blasts from Nick Senzel and Aristides Aquino.

The Kansas City Chiefs fought back from another double-digit deficit sparked by rookie Jaylen Watson's 99-yard pick six as they won 27-24 over the Los Angeles Chargers on Thursday.

Patrick Mahomes produced a patient display, throwing two touchdowns and completing 24 of 35 passes for 235 yards, leading them back from a 17-7 deficit to make it two wins to start the new season.

Justin Herbert was gallant for the Chargers, playing through considerable pain after a series of fourth-quarter hits, to end with three TD passes, completing 33 of 48 passes for 334 yards but with one interception.

That interception came in the fourth quarter with scores locked at 17-17, with Herbert aiming for Gerald Everett on the goalline, only for Watson to clasp it and race away for the game-winning TD.

The Chargers had led 10-7 at half-time, with rookie Alexander Horvath making it two touchdowns in his first two games, before Mahomes' side-arm fastball found Jerick McKinnon for the reply, moving him past Alex Smith for the third-most completions (1,588) in franchise history in the process.

Mike Williams, who had eight receptions for 113 yards, plucked a remarkable one-handed catch under tight coverage from L'Jarius Sneed to put the Chargers up 17-7.

The Chargers were left frustrated after two interceptions were overturned before Mahomes found Travis Watson with a 41-yard pass to score. The Chiefs would pile on 20 unanswered points after rookie Watson made his pick six before Matt Ammendola converted a 32-yard attempt.

Herbert found DeAndre Carter with a late dart before showing poise under apparent duress from a fourth and goal to hit Josh Palmer to make it 27-24. The Chargers confirmed after the game that Herbert would undergo an X-ray.

Serena Williams has paid tribute to retiring 20-time grand slam winner Roger Federer, describing her admiration for him and welcoming him "to the retirement club".

The 41-year-old confirmed on Thursday that he would bring an end to his illustrious playing career after the Laver Cup later this month.

Federer's announcement comes only weeks after 23-time major winner Williams declared her intention to step away from tennis, culminating at the US Open earlier this month where she bowed out in the third round.

The Swiss icon will bow out with 20 major titles to his name, a feat bettered by only two male players – Rafael Nadal (22) and Novak Djokovic (21). Williams sits behind only Margaret Court (24) for women's singles major titles.

"I wanted to find the perfect way to say this, as you so eloquently put this game to rest – perfectly done, just like your career," Williams wrote on Instagram.

"I have always looked up to you and admired you. Our paths were always so similar, so much the same.

"You inspired countless millions and millions of people – including me – and we will never forget. I applaud you and look forward to all that you do in the future.

"Welcome to the retirement club. And thank you for being you @rogerfederer."

Williams has deliberately avoided the use of the word retirement since declaring her intention to 'evolve' away from tennis, meaning the latter comment is of note.

The 40-year-old American has teased at a potential return to tennis, saying on Good Morning America this week that "Tom Brady started a really cool trend", referencing his decision to come out of retirement.

Justin Lower has kicked off the new PGA Tour season in style, shooting a nine-under 63 in the opening round of the Fortinet Championship to lead by two strokes.

Lower posted nine birdies and nine pars in his bogey-free round, bookending his day with birdies on the first and last holes.

Coming into his second year on the PGA Tour, Lower has two top-10 finishes to his name, making the cut in 16 of his 28 events this past campaign.

Alone in second place at seven under is Max Homa, who was part of the late starters able to finish their rounds right before play was halted due to darkness, with some competitors still not completing the 14th hole.

Tied for third place is J.J. Spaun along with two South Koreans, An Byeong-hun and Kim Seong-hyeon, with the trio shooting 66s.

There is a nine-man logjam at five under, which includes veteran Rickie Fowler as he tries to rediscover some form this season, as well as rising talent Sahith Theegala and Argentina's top player Emiliano Grillo.

Also at five under is Robby Shelton, who will resume play with six holes to play with a chance to climb the leaderboard even further before starting his second round.

One shot further back at four under is a group that includes Matt Kuchar and Canada's Adam Svensson, with major champions Hideki Matsuyama and Danny Willett at three under.

Both Lleyton Hewitt and Richard Gasquet used their media availability at the Davis Cup on Thursday to give their respect to Roger Federer after he announced his retirement on social media.

Federer, 41, won the first of his grand slams in 2003 at Wimbledon, and in that tournament it was Hewitt who was the reigning champion after becoming the youngest ever world number one back in 2001.

They came through in the same era, with Federer quickly overtaking the Australian as the sport's top attraction, and he would retain that mantle for over a decade as he and Rafael Nadal began their legendary rivalry.

Reflecting on their time on tour together, Hewitt called him "nearly unbeatable" as he shared his admiration.

"Yeah, he was from my kind of era, I guess," he said. "We were the same age, we grew up together in juniors. 

"I knew Roger extremely well and probably saw him slightly different to everyone else as well, because we grew up together. But he was the greatest of that time. 

"You know, obviously there are a couple of other guys now that are really putting their hand up, but he went clear easily from a grand slam perspective and really just his win-loss ratio [in the] mid-2000s era, he was nearly unbeatable. 

"It was pretty much only Rafa [Nadal] that could get him, especially on the clay. But most of all he's been a great ambassador for our sport. 

"I've always said that you don't want to push those guys out of the game too early. 

"Everyone wants to talk about retirement. When are they going to retire? You want to hold on to those greats. They've done so many special things for our sport. 

"But yeah, obviously, the body – you get to my age and his age now, and it's not easy. He's done everything in the sport that you could ever dream of."

In his own interview, Gasquet shared the sentiment, declaring "there is only one Roger Federer".

"It is a big shock – he is a legend of the game," he said. "It's not easy for anybody, I know it will be a big thing at the Laver Cup. I'm sure it will be wonderful there. 

"It's a tough loss for tennis. It will be different after that. It's still tennis, but it won't be the same without Federer.

"I was leading 1-0 against him [head-to-head], I won in Monte Carlo – but after that I lost maybe 20 times. I'm not the only one of course, it was incredible when I got to face him. 

"He is a legend of the game, everybody knows it. The technique, the charisma – everything was crazy. There is only one Roger Federer."
