Max Verstappen went top of the Formula One drivers' standings for the first time in his career but admits he faces a huge fight to stay ahead of Lewis Hamilton.

The Red Bull star earned a maiden Monaco Grand Prix victory as Hamilton trailed in seventh, with the Mercedes team as a whole enduring a desperate day.

Valtteri Bottas was forced to retire from the race while running second when the pit crew were unable to remove a tyre, with Verstappen and fourth-placed Sergio Perez nudging Red Bull above Mercedes at the summit of the constructors' standings.

Neither Verstappen nor his team would be presumptuous enough to suggest this changing of the guard at the top of each championship is anything but potentially fleeting though, given the margins are so tight and this was just the fifth stop-off in a 23-race season.

"It's so special around here to win and to be for the first time on the podium here," Verstappen said. "It's an amazing race and you really have to keep your focus, but it's really cool.

"You never know what's going to happen, but it was all about looking after your tyres and finding a good stop gap of course. The others went earlier so that made it a bit easier for me, but it was pretty much in control.

"Of course you always want to win this grand prix. I remember when I was very little watching this grand prix and to be standing here of course I'm very proud.

"But I'm also thinking ahead. It's still a very long season, but this is a great way to continue."

Hamilton has won the last four championships and six of the last seven, while Mercedes are chasing an eighth consecutive team title.

They will have many better Sundays in the coming months, and a team statement on Twitter summed up their dismay at the Monaco outcome.

The statement said: "Tough one to swallow. This has been one of our hardest days as a team in a very long time. We have to accept it, own the failure, learn from it and move on from here."

Carlos Sainz finished second, with Verstappen keeping the Spaniard at a safe distance.

It was close to a nine-second gap at the finish, as Sainz delivered for a Ferrari side who had to stomach the pre-race blow of withdrawing pole-sitter Charles Leclerc.

Monaco native Leclerc majorly damaged his car with a heavy crash in qualifying, and despite subsequent assurances that he would be on the grid, Ferrari changed their minds just minutes before the race began, citing a problem with the left driveshaft.

As Leclerc licked his wounds, Sainz delivered a sterling drive for his first Ferrari podium finish. Even then, it felt bittersweet.

"It is a good result," said the 26-year-old Spaniard. "If you had told me before coming to Monaco that I would finish second, I would definitely have taken that.

"It's just the whole circumstances of the weekend, having Charles on pole, me missing out in qualifying yesterday on a good lap, it just maybe doesn't taste as good as it should.

"But if I reflect back in the week I will be very happy and proud of the weekend. And I think Ferrari as a team need to be proud about the team and the step they've done this year.

"When you see the other car not starting from pole, all of a sudden the responsibility relies on you, trying to salvage the weekend. I felt the team deserved at least a podium this weekend."

Third place went to Lando Norris, whose McLaren team-mate Daniel Ricciardo, a former winner in Monaco, could only finish in a lowly 12th place.

"I didn't think I'd be here," Norris said, at his post-race interview. "It's always a dream to be on a podium here.

"It's extra special, I didn't think it was going to happen. It's special here, so I'll cherish it."

Max Verstappen roared to victory at the Monaco Grand Prix and jumped above reigning Formula One champion Lewis Hamilton at the top of the drivers' standings.

The Red Bull driver benefited from the shock withdrawal of pole-sitter Charles Leclerc ahead of the race, producing an immaculate drive to stay out of trouble and finish ahead of the Ferrari of Carlos Sainz.

McLaren's Lando Norris completed the podium, securing his second third place of the season, with Sergio Perez, Sebastian Vettel and Pierre Gasly all coming home ahead of Hamilton, who trailed in a distant seventh.

The outcome saw Verstappen, thanks to his first Monaco triumph, move four points in front of Hamilton after five rounds of the 23-race championship. He leads the championship for the first time in his career, a further sign that Hamilton could face a major battle to cling to his crown as he chases a record-breaking eighth title.

Just 20 minutes before the race began, Ferrari dropped the bombshell that Leclerc had been ruled out due to a driveshaft problem.

It was a crushing blow for the Monegasque driver, whose pole was secured in dramatic fashion on Saturday when he crashed his Ferrari in the final minute of qualifying, denying his rivals a clear track and the chance to set a faster time. Leclerc feared gearbox trouble but was initially given the all-clear to race, until he was pulled from the line-up.

What it meant was that Verstappen, second on the grid, had the chance to gain the early ascendancy on the tight circuit where he had never previously achieved a podium finish, and he demonstrated his prowess as a front-runner.

Valtteri Bottas was sitting second when the Finn pitted on the 31st lap, and he joined Leclerc in the bad-luck club when Mercedes were unable to remove his front-right wheel. After a desperate minute of waiting, Bottas climbed out of his car, his race over.

Sebastian Vettel managed to get ahead of Pierre Gasly and Hamilton when the three pitted, the Aston Martin going almost wheel to wheel with Gasly's Alpha Tauri as he completed a stunning overcut.

That moment imperilled Hamilton's leadership of the championship, putting him down in seventh place, as Mercedes suffered a miserable couple of minutes. 

It proved the last major twist of the race, with Hamilton securing a bonus point for a late fastest lap. Small consolation on a dismal day for Mercedes, as Verstappen and Perez's performance also saw Red Bull go ahead of the Silver Arrows in the constructors' standings.

Stefanos Tsitsipas teed himself up for the French Open in dominant fashion as he claimed his second title of 2021 with a straight-sets win over Cameron Norrie at the Lyon Open. 

Tsitsipas looked sharp throughout the week in central France and was in clinical form on Sunday, pouncing on some minor mistakes from Norrie to triumph 6-3 6-3. 

Norrie was by no means an easy opponent, but five double faults handed Tsitsipas an edge he duly made the most of. 

This year's Monte Carlo champion had to claw back three break points in the opening game of the match but was firmly in control from then on. 

A break to make it 5-3 enabled the Greek to serve for the first set – an opportunity he took at the first time of asking – and another clinical break put him 4-3 up in set two.  

Tsitsipas' third and final break came on the second match point on offer, with Norrie overhitting a forehand to seal the world number five's 33rd Tour win of the season.  

Having dropped just one set throughout his run this week, Tsitsipas will now switch focus to Roland Garros, where he reached the semi-finals in 2020.  

"I felt in a good shape from the beginning of the tournament, felt like things were going my way," he said in a post-match interview.  

"I'm proud of today's match. I knew it would be a difficult one against Cameron who has played great this week, winning against good players and showing what his left hand can do on clay. I had to handle the nerves and I'm proud of my performance and the way I stayed focused.  

"It's about getting there [Paris] as early as possible, getting in practice and getting in shape for the big Parisian grand slam which I adore and love. Hopefully, something good can come out of it." 

Charles Leclerc's hopes of finally succeeding at his home grand prix were ended for another year in late, frustrating fashion at Monaco on Sunday.

Leclerc set the fastest time in qualifying but then crashed, cutting short the session to secure pole position yet leaving his Ferrari damaged.

The Scuderia tested Leclerc's gearbox on Saturday and again on Sunday, attempting to avoid a change that would mean giving up their place on the front row with a grid penalty.

The Monegasque star was cleared to take his position on pole less than three hours before the race, but Ferrari's determination not to replace the gearbox seemed to have proved costly.

A driveshaft issue was revealed when running the car, which meant Leclerc was unable to start the race, leaving his precious pole position vacant.

The problem was "impossible to fix in time for the start of the race", Ferrari said just 18 minutes before the scheduled start.

Max Verstappen had a clear run from second on the grid, as Leclerc rued another painful weekend at his home event.

His previous two Monaco appearances saw him fail to finish, although he completed enough of the 2018 grand prix to come 18th. At no other circuit has Leclerc had to retire twice.

The 23-year-old was denied the opportunity to surpass Louis Chiron's result as the best from a Monegasque driver at their home race. 

Chiron came third for Maserati in 1950, the first ever Formula One Monaco Grand Prix.

Carmelo Anthony was shocked to face booing from Denver Nuggets fans – before he and the Portland Trail Blazers silenced the home crowd in Game 1 of the playoff series.

Portland scored a 123-109 road win to get the early upper hand in the best-of-seven series.

The Denver fans that once worshipped Anthony got on his back in Saturday's game, jeering the 10-time All-Star who began his career as a teenager with the Nuggets.

"It's cool man. I love them too. I love those guys too," said Anthony afterwards.

"It's been what, almost 10 years now since I've been here. The love is there man. They love me, they hate me. I can't do nothing about that.

"I've just got to go out there and smile, enjoy myself and have fun and play basketball. Whatever they have to say, let them say, it's not my concern."

Asked if he could explain the fans' reaction, Anthony, who scored 18 points, was stumped.

"I don't have that answer. I don't know what it is," he said. "I gave my all here for seven and a half, eight years.

"I never said anything bad about Denver, the fans, the organisation, the players, I never complained. It's like I was birthed here with the Denver Nuggets. I started my career here and this will always be a special place for me."

It was Anthony's first win back in Denver since he departed in February 2011 to join the New York Knicks.

Coming up for his 37th birthday next Saturday, it was high time he tasted that winning feeling back in his one-time home city.

"I didn't even know that, this is the first win since I got traded," Anthony said.

"It's not even something I ever even thought about, to be honest with you.

"Somebody told me that when I was in the locker room after the game but I'll take it. I'll take my first win being Game 1 of the Western Conference playoffs.

"It's a great time to make it happen, get that first win here in Denver."

James Harden said the Brooklyn Nets took "a huge step" by shaking off sketchy offensive form to overcome the Boston Celtics in Game 1 of their playoff series.

Brookyln's big three scraped together sufficient points to make it comfortable enough in the end, the home team grabbing a 104-93 win, having trailed 53-47 at halftime.

Kevin Durant had 32 points and 12 rebounds, Kyrie Irving added 29 points and Harden weighed in with 21 as the Nets proved too strong for a Celtics side who had 22 points on six-of-20 shooting from Jayson Tatum.

Harden said: "We just engaged. Everybody that steps on the floor is engaged and pretty much knows what they have to do. So everybody had each other's back.

"No matter what happens offensively, defensively is where we show some improvement and tonight was a huge step for us."

With fans back in Barclays Center, Harden suggested their presence may have been a slight distraction, as might the pressure of starting a playoffs tilt.

But ultimately he settled on it being the players' failure to convert opportunities as the reason the Nets took so long to get going.

"We just didn't make shots. I'm sure if we made shots it would be a different conversation," he said.

Asked about Tatum, Harden said: "He's going to be better in Game 2 and we will too."

Durant reached a similar conclusion to Harden.

"We couldn't make shots, I felt like," Durant said. "When we tried to bust the game open seven or eight points, we got open threes we didn't make. We got our scorers in position, but I know I missed a lot of bunnies that felt good leaving my hand.

"But we stuck with our defense. We didn't let that get in the way of what we wanted to do out there. We helped each other and boxed out well. We've got to keep that same effort going into Game 2."

From 82-79 up, the Nets went on a scoring surge and pulled 99-82 ahead in the fourth quarter, before easing to victory.

Irving, prominent in that dominant run, said: "I just think we needed a little separation, just to settle in for the rest of the game. Fourth quarter, we've had the tendency of taking our foot off the gas pedal, of stopping attacking the rim or settling for jump shots or just not swinging the ball around and making easy plays for one another.

"Obviously we know we have all-world one-on-one players, but we make it a little easy when teams can just load up and our one-on-one game isn't working. You can see anything can happen at the end of the game. Kemba [Walker] hits two big threes, we get a flagrant foul. Anything can happen, especially against the Celtics.

"That lucky Irishman is always around the Celtics, so we've just got to be aware of anything against the Celtics. And I think we did a good job of kind of withstanding their runs down the stretch."

Damian Lillard is used to having the game in his hands, but the Portland Trail Blazers star found another level of control Saturday in a 123-109 playoff win over the Denver Nuggets. 

Lillard scored 34 points and had a career playoff high 13 assists to account for 54 per cent of Portland's points in Game 1 of the best-of-seven series. 

That assist total was the most for a Portland player since Damon Stoudamire had 13 against the Phoenix Suns on May 13, 1999. 

The sixth-seeded Blazers set a franchise record for a playoff game in hitting 19 three-pointers, five of them by Lillard, as they opened with a critical road win to boost their chances of taking the series. 

"Any time you start a series on the road, you're going into it thinking we need to at least win one -- heading back home we've got to have one of those first two," Lillard told reporters.

"It's a major statement to be able to get the first one." 

The Blazers heaped praise on center Jusuf Nurkic, who spent most of the night defending Nuggets star Nikola Jokic. 

Though Jokic matched Lillard's scoring output with 34, he had only one assist -- a career playoff low. 

Lillard told reporters he believes Jokic is the NBA MVP this season, but said the Blazers' focus was on letting him do the work himself rather than distributing to his team-mates. 

That formula worked in the series opener, though Lillard expects the competition is "only going to get harder from here." 

Added Carmelo Anthony, "I've been here multiple times. We don't want to get too high -- it's just the first game.

"We'll take it, though. It's a big win. Any time you can get Game 1 on the road in the playoffs it's a major win. 

"We don't look at it as a steal -- we came in here and we earned this win tonight."

Seven strong innings from Walker Buehler lifted the Los Angeles Dodgers to a 6-3 victory at San Francisco, pulling the defending World Series champions level with the Giants in the National League West. 

Buehler allowed one run while scattering six hits in seven innings of work, improving to 3-0 while lowering his ERA to 2.78. 

The Dodgers spoiled the first MLB appearance since September 2016 for Giants starter Scott Kazmir, who allowed only a first-inning solo home run to Max Muncy in four strong innings after being recalled from the minor leagues. 

Austin Barnes added a solo homer of his own in the fifth for the Dodgers, who put the game away with four runs in the seventh and eighth innings. 

The Dodgers' sixth consecutive win and second in a row against their northern rivals left Los Angeles a game behind the first-place San Diego Padres in the top-heavy division. 

Cole silences White Sox

Gerrit Cole was all but untouchable once again, allowing four hits in seven innings as the New York Yankees blanked the Chicago White Sox 7-0 for their fifth win in succession. Gleyber Torres had another big game at the plate for New York, driving in four runs. 

A day after hitting a walk-off home run against the Houston Astros, Texas Rangers sensation Adolis Garcia hit two more bombs to help the Rangers to an 8-4 triumph. The second shot tied the game and sparked a five-run seventh inning that provided the winning margin for Texas.

Garrett Cooper hit a game-winning two-run homer in the bottom of the ninth as the Miami Marlins beat the New York Mets 3-1. 

Xander Bogaerts and Danny Santana had back-to-back homers to lead off the sixth inning for the Boston Red Sox in a 4-3 victory ove the Philadelphia Phillies. 

The Tampa Bay Rays rallied with runs in the eighth and ninth to defeat the Toronto Blue Jays 3-1 for their ninth consecutive victory. 

Mariners' three errors boost Padres

The Seattle Mariners committed three errors in the fifth inning -- two of them by catcher Tom Murphy -- to help the Padres break open what had been a 1-1 game on the way to a 6-4 San Diego win. The first run of the inning scored when Murphy's throw to third on a Jorge Mateo steal attempt sailed into left field. Later, a bases-loaded single by Eric Hosmer brought home two runs, and a throw home by outfielder Jarred Kelenic went through Murphy's legs, allowing Fernando Tatis Jr to score from first base on the play. 

Hernandez gives Cleveland walk-off win

Cesar Hernandez hit a two-run homer in the bottom of the 10th to give the Cleveland Indians a bounce-back 5-3 win over the Minnesota Twins.

Rays at Blue Jays

The Toronto Blue Jays (23-21) send ace Hyun Jin Ryu to the mound as they try to avoid a sweep and stop the Tampa Bay Rays' nine-game winning streak. Michael Wacha will come off the injured list to start for the Rays (28-19). 

A strong second half sent the sixth-seeded Portland Trail Blazers to a 123-109 victory over the third-seeded Denver Nuggets as the NBA playoffs began Saturday. 

Portland outscored Denver 65-48 after the break as Damian Lillard had 34 points and 13 assists for the visitors, who made 18 of 19 free throw attempts to just four of eight for the Nuggets. 

CJ McCollum added 21 points and Carmelo Anthony scored 18 in just 22 minutes off the bench for Portland, who beat the Los Angeles Lakers in their playoff opener last season only to lose the next four to the eventual champions. 

Their efforts overcame a 34-point, 15-rebound game from Nikola Jokic and 25 points from Michael Porter Jr.

Porter made all 11 of his two-point field goal attempts Saturday but was just one of 10 from three-point range. 

Game 2 is Monday in Denver. 

Brooklyn's big three carry Nets

Big games from the big three carried the Brooklyn Nets to a 104-93 series-opening win over the Boston Celtics. Kevin Durant had 32 points and 12 rebounds while Kyrie Irving added 29 points and James Harden 21 as the Nets stifled the Celtics, who got 22 points on just six of 20 shooting from Jayson Tatum in a losing effort. 

Luka Doncic had his third triple-double in seven career playoff games, scoring 31 points with 10 rebounds and 11 assists as the Dallas Mavericks pulled out a 113-103 road win at the Los Angeles Clippers to open their series. Tim Hardaway Jr added 21 points on eight of 13 shooting for the fifth-seeded Mavericks, while Kawhi Leonard had 26 points and Paul George 23 to lead the Clippers. 

Butler cannot find the range

Jimmy Butler came close to recording a triple-double with 17 points, 10 rebounds and eight assists in the Miami Heat's 109-107 overtime loss to the Milwaukee Bucks, but the five-time All-Star made only four of 22 shots from the field. 

Middleton gives Bucks win

Khris Middleton's contested jumper with 0.5 seconds remaining in overtime gave the Bucks the Game 1 win at home. Middleton's 27 points led the Bucks, with Giannis Antetokounmpo adding 26 points and 18 rebounds. 

Saturday's results

Milwaukee Bucks 109-107 Miami Heat (OT)
Dallas Mavericks 113-103 Los Angeles Clippers
Brooklyn Nets 104-93 Boston Celtics
Portland Trail Blazers 123-109 Denver Nuggets

Lakers face Suns

LeBron James and the Los Angeles Lakers got the win they needed in the play-in tournament and they will open the playoffs proper with Game 1 of their best-of-seven series against the second-seeded Suns in Phoenix. 

Far from feeling the pressure as the NBA playoffs got underway Saturday, Luka Doncic was right back in his comfort zone. 

A year after a spectacular showing in a first-round series loss to the Los Angeles Clippers, the young Dallas Mavericks star was at his best again as the two teams faced off once again Saturday. 

Doncic had 31 points, 10 rebounds and 11 assists as the Mavericks took the opening game 113-103 in Los Angeles. 

It was the 22-year-old's third triple-double in seven career playoff games -- a first in NBA history. 

"Playoffs are fun, and especially they are more fun if you win, obviously," Doncic told reporters after the game. "It's fun basketball."

Particularly when the Slovenian is on his game, as he usually is. 

Doncic averaged 31.0 points, 9.8 rebounds and 8.7 assists in last year's 4-2 series loss to the Clippers, right in line with his Game 1 showing Saturday. 

The Clippers threw a variety of defensive looks his way, but he managed to either find the shot he needed or get the ball to someone else. 

"He's a very unique player for a 22-year-old," said Mavs coach Rick Carlisle.

"The level of poise that he has, and his ability to slow down the game, to see what's going on -- even when the [shot] clock is at six or seven seconds, he still is able to slow it down and hold that ball just long enough to get a team-mate a great look.

"He was great tonight and I thought his defense was very good, too."

Carlisle also said he thought Doncic was at his best on the kind of stage the playoffs offer. 

Asked whether he agreed, Doncic deflected the praise, pointing to his youth. 

"I hope I'm at my best, but I think that's far away," he said. "I'm only in my third season, so I've got still a lot to learn. 

"We just go out there and have fun and try to win the game."

Phil Mickelson's dream week at the US PGA Championship continued Saturday, putting him in position to become golf's oldest major championship winner. 

The 50-year-old survived early on the back nine to shoot 70 and hold a one-stroke lead over Brooks Koepka at seven under par for the tournament. 

He knows he does not have many chances left to collect his sixth major title, but he said he's trying to keep his focus on his game rather than thinking about the big-picture implications. 

"I think that because I feel or believe that I'm playing really well and I have an opportunity to contend for a major championship on Sunday and I'm having so much fun that it's easier to stay in the present and not get ahead of myself," Mickelson told reporters. 

Mickelson opened a gap on the field early on moving day with birdies on four of his first seven holes, then another at the 10th. 

"I felt I had a very clear picture on every shot, and I've been swinging the club well, and so I was executing," he said of that stretch. "I just need to keep that picture a few more times."

The picture got a bit fuzzy at 12 and 13, where Mickelson went bogey-double bogey. 

He said his focus slipped on those two holes. 

"It's just an example of losing the feel and the picture of the shot, and I get a little bit jumpy, a little bit fast from the top, and it just -- when that happens I get narrow and I end up flipping it," he said. 

"So those two swings were more a product of not staying or keeping the feel and the focus of the shot. And so that's just a small little thing that I need to iron out."

Mickelson finished the round with five consecutive pars to ensure his place atop the leaderboard heading into Sunday. 

His remarkable week has put him in position to surpass Julius Boros, who won the 1968 PGA at age 48, as the oldest major winner, but Mickelson was in no mood to ponder what he already had accomplished just by getting this far. 

"I'm more focused on a few things that I need to work on tonight before tomorrow's round, and I'm not really dwelling back on what took place today," he said. 

"I just know I'm having a lot of fun and I'm very appreciative of the way the people have been supportive."

Brooks Koepka is exactly where he expects to be heading into the final round of a major, particularly the US PGA Championship. 

After carding a two-under-par 70 on Saturday, Koepka sits one stroke back of leader Phil Mickelson at six under for the tournament, putting him in position to win his fifth major championship. 

Considering Koepka has been no worse than tied for fourth after 12 of the last 13 rounds at the PGA, his spot in Sunday's final pairing is familiar territory. 

"It just feels good, feels normal," Koepka told reporters after his round. 

"It's what you're supposed to do, what you practice for.

"I'm right where I want to be, and we'll see how tomorrow goes.

"Just be within three of the lead going into the back nine and you've got a chance."

Koepka trailed Mickelson by five strokes at one point Saturday but saw the five-time major winner slide back to him on the back nine. 

A bogey on 18 denied Koepka a chance to match Mickelson at seven under, but the 2018 and 2019 PGA winner is looking forward to a potential one-on-one showdown in the final round. 

"I can see what he's doing, and everybody else is in front of me, so I'll have a good idea on the leaderboard what's going on and just need to putt better -- simple," Koepka said.

"If I strike it anything like I did the last three days, I'll have a chance."

If he can pull it off, Koepka would become the first player to win the same major three times in a four-year stretch since Tom Watson captured the Open Championship title in 1980, 1982 and 1983.

Though the wind that had made scoring difficult at Kiawah Island's Ocean Course the first two days died down a bit Saturday, Koepka anticipates a challenging final round. 

"it's a tough golf course," he said. "I thought it definitely played easier for sure, but this golf course you can make one little mistake and it can be costly.

"That's why it's a major championship. I think this place is perfect for it, and it will be fun to watch tomorrow."
