Lewis Hamilton was pleased with the "small step forwards" taken by Mercedes after setting the second-fastest time in practice ahead of the British Grand Prix.

The Briton was 0.163 seconds slower than pace-setter Carlos Sainz in FP2, while compatriot Lando Norris was third and championship leader Max Verstappen in fourth.

Hamilton has yet to win a race this season, but he offered plenty of promise heading into a big weekend on home soil at a packed Silverstone with his performance in practice.

However, the seven-time world champion offered a word of caution over the ongoing porpoising issue that has dominated recent races.

"It's bouncing still, quite a bit," he said. "Not necessarily on the straights but through the corners it's pretty harsh – not physically harsh but in the car on the tyres and everything.

"So we still have work to do but it feels like a small step forwards.

"Our long run pace isn't as good as the other guys but it's not miles off. We've definitely made an improvement. I'm sure overnight we can work and improve the car a bit more."

Hamilton may have endured a difficult campaign to date, lagging as he does 98 points behind leader Verstappen, but he boasts an impressive record on his home turf.

The 37-year-old has won the British Grand Prix eight times and could become the driver to have won the most races at a single Grand Prix with victory this weekend.

Mercedes, meanwhile, have recorded eight of the last nine wins at Silverstone, while also taking eight of the last nine poles.

McLaren driver Norris looks good value to challenge for a second podium of 2022 after a surprising rise up the timesheets, having finished 15th last time out in Canada.

"As good as it looked, it is still difficult to put things together and be consistent but I am happy," he said.

"The car seems to be in a decent place, at least a little better than we were expecting."

Friday was rather unimpressive for Red Bull's Verstappen, who has won six of the nine races this year, including five of the last six.

But the Dutchman – who is out to surpass Valtteri Bottas and equal Rubens Barrichello as the driver with the eighth-most podiums ever (68) – is confident of finding improvement.

"It's always a bit tricky, of course, after not driving in FP1 and then FP2 becomes a bit of guessing, let's say it like that," Verstappen said. 

"It was maybe not ideal, but also not a big issue. I think we know what we have to work on and that's what we'll try to do overnight. 

"But, again, tomorrow probably it's raining so you have again different kinds of conditions. This time probably was not amazing, but it was also not really bad."

Yves Lampaert claimed a shock victory on stage one of the Tour de France in rainy conditions in Copenhagen to take the first yellow jersey of this year's race.

The Quick-Step Alpha Vinyl rider came out on top in Friday's opening 13.2-kilometre time trial in a time of 15 minutes and 17 seconds.

Lampaert dislodged Belgian countryman Wout van Aert, who finished five seconds back, while Tour favourite Tadej Pogacar was a further two seconds behind in third.

Time trial world champion Filippo Ganna and fellow heavyweight Mathieu van der Poel completed the top five, but it was surprisingly Lampaert who was celebrating at the end.

An emotional Lampaert said in his post-race interview: "My mind is exploding right now – I can't believe it. Top 10 would have been my expectation but to win is unbelievable.

"I know I'm in good condition, but to win the first stage of the Tour de France, the prologue, is something I never dreamed of.

"To beat Van Aert, Van der Poel, Ganna… it's unbelievable for me."

Lampaert, the fourth Belgian to win the opening time trial in the Tour de France, added: "I'm just a farmer's son from Belgium, eh."

Despite finishing in third, Pogacar confirmed his status as the overall favourite for a third title in a row by finishing as the best of the likely general classification racers.

The Slovenian laid down a marker when posting a time of 15:24, enough to finish just behind Team Jumbo-Visma's Van Aert, who was then usurped by Lampaert.

Elsewhere on stage one of the 109th edition of the race, Jonas Vingegaard and Primoz Roglic conceded eight and nine seconds to Pogacar respectively.

Tatjana Maria bumped Maria Sakkari out of Wimbledon as the German who once played at the All England Club while pregnant condemned the Greek star to a stunning exit.

Mum-of-two Maria dazzled in a 6-3 7-5 victory over the fifth seed, reaching round four of a grand slam for the first time in her career. She had suffered eight successive first-round losses in slams until this week's turnaround, last getting a win at the 2018 US Open.

The inspired Maria revelled on the Court Two big stage, becoming the oldest German woman in the Open Era, which began in 1968, to make it through to the last-16 stage of a major.

At the age of 34 years and 228 days, world number 103 Maria is also the oldest woman remaining in the Wimbledon singles this year.

Sakkari lost in two tight sets to Maria at the Australian Open in January, but the roles were reversed this time, the impressive German landing a fifth career win over a top-10 player.

Husband and coach Charles-Edouard Maria watched from the stands, while their daughters, eight-year-old Charlotte and one-year-old Cecilia, played in a nearby creche.

Maria said in an on-court interview: "I came here with my two kids for the first time. I was so happy to be in the main draw. I love to play on grass. It's such a special place for me. One year, when I was in my first pregnancy, I played pregnant.

"I love to play Wimbledon and to make this happen with my family there are no words for this, only joy and only happiness."

She said her daughters were probably "jumping in front of the TV", and spoke of wanting to set a positive example for her tennis-playing elder daughter.

"I try to be really a role model for my daughter, because she will be the next champion, so I try to show her the best way possible," Maria added. "I cannot wait to go over to the creche now and see my kids."

Neither Maria nor Sakkari had ever gone beyond round three at Wimbledon, with this the one grand slam where the Greek world number five has not reached the last-16 stage.

Maria was one of three mothers in the draw, the WTA said, along with Serena Williams and Yanina Wickmayer, both of whom made early exits. The next test for Maria will be posed by big-hitting Latvian Jelena Ostapenko.

The Indiana Pacers have agreed to trade point guard Malcolm Brogdon to the Boston Celtics, ESPN's Adrian Wojnarowski reported on Friday, bolstering the backcourt of the reigning Eastern Conference champions. 

Indiana are getting a 2023 first-round draft pick from the Celtics, along with Daniel Theis, Aaron Nesmith, Nik Stauskas, Malik Fitts and Juwan Morgan. 

The Celtics set out to find a traditional point guard this offseason after last season's NBA Finals run came up short largely due to a high turnover rate.  Boston committed 353 turnovers during their 24-game playoff run, the most since the 2003 San Antonio Spurs (365). 

Jayson Tatum was responsible for 100 of those turnovers, the most by a player in a single postseason since the league started tracking turnovers in 1977-78.

Brogdon averaged 19.1 points, 5.1 rebounds and 5.9 assists last season for Indiana but was limited to just 36 games by a lingering injury to his right Achilles tendon. 

A second round pick out of Virginia, Brogdon spent his first three seasons with the Milwaukee Bucks and won Rookie of the Year in 2016-17. He has spent the past three seasons with the Pacers. 

Even after acquiring Brogdon, Boston top executive Brad Stevens may not be done adding to the Celtics' roster.

ESPN reported earlier on Friday that veteran forward Danilo Gallinari – who was traded to the Spurs and was then to be waived – has identified Boston as his preferred landing spot. 

Zach LaVine will be staying with the Chicago Bulls after the All-Star guard agreed to a five-year, $215.2million maximum extension on Friday.

LaVine's agent, Rich Paul of Klutch Sports, confirmed the agreement to The Athletic. The deal contains a player option for nearly $49m in the final year.

Acquired from Minnesota in 2017 as part of a draft-day trade that sent six-time All-Star Jimmy Butler to the Timberwolves, LaVine has emerged as one of the NBA's most consistent scorers during his time in Chicago. The 27-year-old joined the legendary Michael Jordan as the only players in franchise history to average 23 or more points per game in four consecutive seasons after averaging 24.4 per game in 2021-22.

LaVine also shot 38.9 per cent from three-point range and 85.3 per cent from the free throw line this past season to earn his second straight All-Star nod and help the Bulls reach the playoffs for the first time since 2016-17.

By retaining LaVine, the Bulls keep a core intact that also consists of 2021-22 All-Star DeMar DeRozan, center Nikola Vucevic and playmaking point guard Lonzo Ball. That group led Chicago to a 46-36 finish last season, their most victories since 2014-15, and a sixth seed in the Eastern Conference.

LaVine was hampered down the stretch of last season by a left knee injury and underwent surgery in May, but is expected to be fully recovered in time for training camp.

Novak Djokovic warned Wimbledon title pretenders his game is improving with every round as he eased past fellow Serbian Miomir Kecmanovic on Centre Court.

Defending champion Djokovic won 6-0 6-3 6-4 in one hour and 53 minutes to book a last-16 clash with Dutch wild card Tim van Rijthoven.

The 20-time grand slam winner will carry out due diligence on Wimbledon rookie Van Rijthoven, who is through to the fourth round on his debut and has reeled off eight successive wins.

Van Rijthoven won the Rosmalen Grass Court Championships in the lead-up to this fortnight, stunning world number one Daniil Medvedev in the final.

Yet on the form that saw Djokovic crush Kecmanovic's hopes, Van Rijthoven will surely stand little hope of going any deeper into the tournament.

Djokovic won 88 per cent of points when landing his first serve in court, and he has now reached the fourth round at Wimbledon on 14 occasions, a performance only beaten in men's singles by Roger Federer (18) and Jimmy Connors (16).

"I thought I started off very, very well, very strong with a lot of good intensity, good focus," Djokovic said in an on-court interview.

"Honestly, I think I've been playing better and better as the tournament progresses, so that's something you wish for as a player, that every match you play you raise a level of tennis up a notch, at least, and I think that's what is happening at the moment.

"I know I can always do better, I always expect the highest from myself, and so far, so good, and I'm looking forward to the next challenge."

Data slam: Familiarity breeds familiar outcome

The battle of these Davis Cup team-mates was always unlikely to go the way of the 25th seed, and so it proved that Kecmanovic could not cope with the animal that Centre Court brings out in Djokovic.

This was a third career meeting in tournament action for the pair, with both previous encounters having come at the Serbia Open. Kecmanovic took the opener against Djokovic before slumping to defeat when they played in Belgrade in April, but this was a rout, the 22-year-old underdog trampled.

WINNERS/UNFORCED ERRORS
Djokovic – 36/19
Kecmanovic– 13/27

ACES/DOUBLE FAULTS
Djokovic – 6/4
Kecmanovic – 1/5

BREAK POINTS WON
Djokovic - 6/12

Another big-serving display from John Isner at Wimbledon means he now has the most ATP Tour aces on record.

Ivo Karlovic – one of only two tennis stars taller than the giant Isner – had set the benchmark with 13,728 across his career, the most since aces were first tracked in 1991.

But Isner has chipped away at that total over the course of this week at the All England Club.

The American's 54 aces in five sets against Enzo Couacaud in the first round made him the first player to pass 50 in a grand slam match since he had last done so versus Steven Johnson at the 2020 US Open.

And there were a further 36 in an epic second-round win over Andy Murray, leaving Isner just four short of matching Karlovic and five away from passing him.

Against Jannik Sinner, in Friday's third round, Isner raced past his target, tallying 12 aces in the first set alone.

It is a record Isner is likely to own for some time, with 43-year-old Karlovic absent from the ATP Tour this year and playing only six main-draw matches in 2021.

Roger Federer is third on the list, way back on 11,478.

The San Jose Sharks have fired head coach Bob Boughner after missing out on the playoffs for a third straight season.

Boughner was in the final year of a contract that would have paid him $1.5million in 2022-23.

He was relieved of his duties on Friday along with assistants John Madden, John MacLean and Dan Darrow in another organisational shake-up for the struggling franchise.

The Sharks are also looking for a new general manager after Doug Wilson stepped down in April for health reasons. Wilson, who had served as GM since 2003, had been on medical leave since November, with assistant GM Joe Will handling his duties.

Boughner compiled a 67-85-23 record after replacing Peter DeBoer in December 2019. The Sharks finished 11th in the Western Conference this past season with a 32-27-13 record, and their three straight seasons of missing the playoffs is the longest stretch in the franchise’s 30-year history.

The 51-year-old previously spent two seasons as the Florida Panthers’ head coach, amassing an 80-62-22 record with no playoff berths.

San Jose have reportedly narrowed down a list for Wilson’s successor. Former Sharks players Ray Whitney and Mike Grier, neither of whom have experience as a GM, are believed to be among the finalists, according to Sportsnet Canada.

The Sharks join the Winnipeg Jets as teams with head coaching vacancies.

Beaming Brit Heather Watson got her reward for years of persistence at Wimbledon by reaching round four of a singles grand slam for the first time.

Watson also earned herself a rare day off, after a hectic start to her campaign, by racking up a 7-6 (8-6) 6-2 victory over 21-year-old Slovenian Kaja Juvan.

In singles, Watson is a four-time WTA event winner and this was a 43rd grand slam main-draw appearance, yet she had only reached the third round in a major four times before this campaign.

Watson, who has lost in round one on all 10 of her US Open singles appearances, now has a last-16 match at Wimbledon inked into her diary, achieving at the age of 30 what many thought would come much earlier in her career. Germany's Jule Niemeier awaits Watson, with a quarter-final place on the line.

Guernsey star Watson's previous best Wimbledon singles runs came in 2012, 2015 and 2017, when she was halted by Agnieszka Radwanska, Serena Williams and Victoria Azarenka respectively.

In mixed doubles, she was a champion with Finland's Henri Kontinen in 2016 and a runner-up in 2017, but singles is where it matters most.

This week she has faced Tamara Korpatsch, Wang Qiang and world number 62 Juvan, a kind run compared to previous Wimbledons, and Watson has taken advantage. She has unusually had to play every day so far, however, with her first-round and second-round matches both spanning two days.

A former world number 38, Watson has drifted to 121st in the WTA rankings. She won just five games when well beaten by Juvan at last year's US Open, but this time it was Watson's day.

It was a match she would have fancied, given Juvan had already lost four times this season to players ranked outside the top 100.

Watson said in an on-court BBC interview: "Wow, what an atmosphere. I actually wasn't that nervous, but first time in the fourth round, I'm so happy. I'm not speechless because I'm blabbing on, but I don't know what to say. It means everything."

She has taken inspiration from seeing fellow Britons Katie Boulter, Cameron Norrie and Liam Broady battle through early matches.

"It really helps. I've watched all of their matches," Watson said. "It's really inspiring, and we're all egging each other on."

Zion Williamson is set to agree a five-year, $231million rookie max extension with the New Orleans Pelicans.

The imminent deal was reported by The Athletic's Shams Charania on Friday, the second day of NBA free agency.

A number of leading stars were given new deals on Thursday – including Nikola Jokic, Devin Booker and Ja Morant – and Williamson should now join them.

The Pelicans are building an exciting young team, making the playoffs in 2021-22 and taking the number one seed Phoenix Suns to six games despite Williamson's injury absence.

New Orleans could be forgiven for having some concerns about committing such a huge sum to Williamson, though.

The former first overall pick has played only 85 games in three seasons in the NBA – albeit he has averaged 25.7 points and 7.0 rebounds per game.

Williamson has spoken of his desire to commit to the Pelicans, but Charania added this deal was expected to include "protections".

DP World Tour chief executive Keith Pelley has hit back at LIV Golf rebels and says sanctions imposed on players were "proportionate and fair".

Lee Westwood and Ian Poulter were among 16 DP World Tour members who were last week fined £100,000 and banned from playing in three events – the first being the Scottish Open next week.

They were sanctioned by the DP World Tour for playing in the inaugural LIV Golf Invitational Series event at Centurion Club without permission last month.

In an open letter, which was addressed to Pelley, published by The Telegraph, the 16 players threatened to take legal action against the DP World Tour if the fines and suspensions were not rescinded.

They also claimed that the DP World Tour is playing "second fiddle" to the PGA Tour in an extended relationship between the two.

Pelley provided a strong response as he refused to back down on Friday.

He said in a statement: "There has been a leak to the media of a letter we received on behalf of a number of LIV Golf players which contains so many inaccuracies that it cannot remain unchallenged.

"Before joining LIV Golf, players knew there would be consequences if they chose money over competition. Many of them at the time understood and accepted that. Indeed, as one player named in the letter said in a media interview earlier this year; 'If they ban me, they ban me.' It is not credible that some are now surprised with the actions we have taken.

"The letter claims that these players 'care deeply' for the DP World Tour. An analysis of the past participation statistics on our Tour in recent years of several of the leading players named suggests otherwise

"One player in particular named in the note has only played six Rolex Series events in the past five years. Another one, only four. I wish many of them had been as keen to play on our Tour then as they seem to be now, based on the fact they have either resigned their membership of the PGA Tour or, if they are still in membership, have been suspended indefinitely.

"Furthermore, given how deeply these players say they care about the DP World Tour, perhaps some of them could have played in Ireland this week in support of our new title sponsor, in particular one player who gave us a signed commitment to play at Mount Juliet.

"With that player currently in action at Pumpkin Ridge, you can imagine the allegation in the letter that we are in the wrong, is hard to accept.

"We also take great exception to an allegation made near the end of the letter which states we are somehow playing 'second fiddle' to the PGA Tour. Nothing could be further from the truth.

"We held a player meeting in Ireland on Tuesday where we outlined in great detail all the many benefits of our expanded relationship with the PGA Tour.

"One of those is an unprecedented ten cards on offer to the PGA Tour, cards that many of the players named in this letter desperately wanted to attain in the early stages of their careers. Why now be critical of those trying to do the same?

"The letter also expresses supposed concern about the future of the DP World Tour. Rest assured no-one should have any worries on that score.

"The DP World Tour is a vibrant, independent and global Tour with increasing and guaranteed prize fund growth over the next five years. We have fantastic tournaments across the year including a host of wonderful national Opens, all played in front of huge crowds, illustrated perfectly by this week's Irish Open.

"Finally, it would not be appropriate for me to comment on any potential legal matters.

"I will simply reiterate that our Members' Regulations which have been in force for more than 30 years, have been accepted by all the players, are there to protect all of our members, and we will use them to take all necessary steps to protect their interests.

"The sanctions for those members who knowingly broke our rules by playing at the Centurion Club without a release are proportionate, fair and, I believe, considered necessary by the majority of our members."
