New York Yankees manager Aaron Boone has taken a medical leave of absence following surgery to receive a pacemaker, the MLB franchise announced.

Boone, who underwent open-heart surgery in 2009, is recovering at St. Joseph's Hospital in Tampa, Florida after Wednesday's operation.

The Yankees said the procedure was "expected", while general manager Brian Cashman added Boone could return to the team within two to three days.

"As many of you know, I underwent open-heart surgery in 2009, and I wanted everyone to understand where I'm at regarding the procedure that's taking place today," Boone said. "Over the last six-eight weeks I've had mild symptoms of light-headedness, low energy and shortness of breath.

"As a result, I underwent a series of tests and examinations in New York prior to the beginning of Spring Training, including multiple visits with a team of heart specialists. While the heart check-up came back normal, there were indications of a low heart rate which, after further consultations with doctors in Tampa, necessitates a pacemaker.

"My faith is strong, and my spirits are high. I'm in a great frame of mind because I know I'm in good hands with the doctors and medical staff here at St. Joseph's Hospital. They are confident that today's surgery will allow me to resume all of my usual professional and personal activities and afford me a positive long-term health prognosis without having to change anything about my way of life.

"I look forward to getting back to work in the next several days, but during my short-term absence, I have complete trust that our coaches, staff and players will continue their training and preparation at the same level as we've had and without any interruption.

"I also want to take this opportunity to remind all those dealing with heart issues to remain vigilant in your care and to reach out to your doctor should you have any symptoms of discomfort or trouble.

"Any issue involving the heart has the potential to be serious. Staying on top of your health is always the first and most important thing you can do for yourself and your family."

Boone has been Yankees manager since 2018, leading the storied franchise to the American League Championship Series (ALCS) in 2019, while they lost in the AL Division Series (ALDS) last year.

The 47-year-old was an All-Star with the Yankees in 2003.

"It's a necessary step,'' Cashman said of Boone's surgery. "It's something that's not avoidable and needs to be taken care of, but he has no fear and I know he's just in great hands and it's just a temporary timeout. He looks forward to getting back to doing what he does best and doing what he loves, which is baseball.'

"When you hear 'pacemaker,' it kind of sets off a lot of alarms of concern... No one's going to do more research than the person that's going to be going through this, and I felt so comforted by the way he communicated with me on it that he put me at ease."

Yankees managing general partner Hal Steinbrenner added: "The thoughts of the entire organisation are with Aaron and his family as he undergoes this procedure and takes the time he needs to properly heal.

"Aaron leads our players, coaches and staff with a rare combination of work ethic, intelligence and a genuine concern for others. Our only priority at this time is Aaron's health and well-being, and we will support him in every way throughout his recovery."

Garbine Muguruza made clear she is "fighting for trophies" on the WTA Tour after knocking out defending champion Aryna Sabalenka at the Qatar Open. 

Muguruza prevailed in a high-quality contest that required a third set to decide the outcome, the world number 16 and two-time grand slam champion eventually triumphing 6-2 6-7 (7-5) 6-3 after two hours, 18 minutes on court. 

Sabalenka had won their only previous meeting but the third seed saw her hopes of retaining the trophy dashed, not helped by only managing to convert four of the 13 break-point opportunities she created in the match. 

Muguruza – who matched 41 winners with the same number of unforced errors – finished in fine style, claiming the final four games in a row to set up a meeting with Maria Sakkari, who defeated Madison Keys in straight sets. 

"I'm very motivated to play top players," Muguruza said in her post-match press conference, according to the WTA Tour's website. "Like everybody, I worked hard. I'm fighting for trophies, to play well in big tournaments, in good tournaments. 

"Today I was facing a top player, and I knew I have to go out there with a big, fighting spirit, and be strong to be able to win against these tough opponents." 

While the 2020 winner is no longer involved, former champions Victoria Azarenka and Petra Kvitova both made it beyond the second round with straight-sets wins in Wednesday's action. 

Azarenka, who claimed the title in 2012 and then returned to successfully retain it a year later, saw off qualifier Laura Siegemund 6-4 6-2. 

Kvitova, meanwhile, eased past Anastasia Pavlyuchenkova. The fourth seed went all the way in 2018 and is now into the last eight this year – a 6-1 6-3 result paving the way for a clash with Anett Kontaveit.

Top seed Elina Svitolina is also through – and will face Azarenka next – after needing little over an hour to defeat Misaki Doi 6-1 6-2.

Karolina Pliskova, the second seed, found life far tougher against Ons Jabeur however, eventually coming out on top 6-4 4-6 7-5 in a thriller.

Meanwhile, at the Lyon Open, second seed Fiona Ferro progressed to the last eight on home soil after opponent Tereza Martincova was forced to retire when 4-1 down in the second set, having already lost the opener too.

Alize Cornet is another French favourite hoping to make home advantage tell in the tournament; the fifth seed rallied from a set down to beat compatriot Clara Burel 1-6 6-1 6-3. 

Andy Murray slumped to defeat to Andrey Rublev at the Rotterdam Open, where both Alexander Zverev and top seed Daniil Medvedev crashed out in Wednesday's action.

Rublev – defeated by Medvedev in the Australian Open quarter-finals – booked his place in the last eight with a clinical 7-5 6-2 victory over the former world number one. 

The world number eight hailed Murray as a "true legend" ahead of the clash, with the Russian and Scot having previously met only once before. 

Murray, then at the peak of his powers, came out on top in the second round of the 2017 Australian Open, thought it was a far different story this time around, Rublev dispatching his opponent with relative ease. 

Rublev saved all three break points that Murray managed to create during proceedings, breaking twice in the second set before wrapping up the win at the first opportunity.

Dusan Lajovic put in an impressive display as he registered a 7-6 (7-4) 6-4 victory over Medvedev. 

A run to the Rotterdam final would have moved Medvedev up to world number two, yet the Australian Open runner-up was well shy of his best. 

The Russian led by a break in the first set, only for Lajovic to hit back to square things up at 3-3, with the Serbian winning the tie-break when Medvedev double-faulted. 

Lajovic looked to have the odds stacked against him early in the second set, yet ultimately fought back again following another unforced error from the world number three to claim his second career win over Medvedev.

Lajovic will now face Borna Coric to tee up a tie with Kei Nishikori, who followed up his opening win over Felix Auger-Aliassime by beating Alex de Minaur 6-3 2-6 7-5 to clinch a quarter-final spot. 

The other shock result during the day came in the form of world number seven Zverev losing 7-5 6-3 to Alexander Bublik. 

It was the biggest win of Bublik's career, with the world number 43 - a finalist at the Singapore Open on Sunday - having now triumphed in his last three matches against top-10 opponents. 

Zverev was playing for the first time since a quarter-final defeat to Novak Djokovic in Melbourne last month. 

Bublik will face American Tommy Paul in the next round, while David Goffin beat Jan-Lennard Struff and Alejandro Davidovich Fokina got the better of compatriot Roberto Bautista Agut. 

Sebastian Vettel is excited to get the 2021 Formula One season underway with Aston Martin, with the former world champion seeing plenty of potential at his new team.

Vettel, a four-time F1 champion, left Ferrari at the end of the 2020 campaign, bringing an end to a six-season stint with the Italian manufacturers.

Charles Leclerc had usurped him as Ferrari's number one driver, and Vettel slumped to a 13th-placed finish in last year's drivers' standings, claiming just one podium finish.

Vettel has now switched to Aston Martin, who have rebranded the Racing Point team to make their F1 return after a 61-year break from the competition. 

The German made no secret of his disappointment at how his final season at Ferrari panned out but is anticipating an exciting debut year with Aston Martin.

"I am not happy with last year in terms of performance – partly my performance – but I accepted it," said Vettel at the unveiling of the AMR21 car on Wednesday, which also featured NFL great Tom Brady and Hollywood star Daniel Craig.

"There are things that didn't go well, but I am looking forward to this year.

"I go racing to win and obviously it's a very exciting project, a new start and a new chapter for the entire team. I'm very much looking forward to it.

"Winning is maybe a bit ambitious straight away, but it's everybody's goal, it's why we go racing.

"Even though I have raced for four Formula One teams and for many years, starting a new season with a new team still gives me a sense of excitement.

"I see potential. I think the team has always been very successful in the past with limited resources, now the regulations in F1 are changing, and with the new launch of Aston Martin coming back, a lot of talented people joining and coming together to this already good group already, I think it's [his arrival is] only an addition.

"So I hope that I can contribute as well, and I think if we keep sharing that joy and passion then good things will follow."

Vettel's Ferrari future was decided before the 2020 season – which was derailed due to the COVID-19 pandemic – had started, yet he claims to have had no doubt that Aston Martin was the right move. 

"As a driver, I have always kept my eye on the competition and this team has consistently impressed me with what they have been able to do without the biggest of budgets," he added.

"So, when Lawrence [Stroll] and Otmar [Szafnauer] approached me last year, and explained what their ambitions were, I was immediately very motivated to join the team.
 
"I love the history of motor racing and Aston Martin is one of the great names of the past, so it is fun to be part of their return to Formula One after an absence of 61 years.  
 
"I have not driven the car yet but I think it looks great. I am really looking forward to getting it out on the track. I am also looking forward to working with and getting to know better everyone in the team, including my team-mate Lance [Stroll]. We will certainly make a big effort to deliver some good results together and have fun doing it."

LeBron James will miss the Los Angeles Lakers' game against the Sacramento Kings on Wednesday, his first absence of the NBA season.

The Lakers fell to a 114-104 home loss against the Phoenix Suns on Tuesday, despite 38 points from James, who was an impressive 16-for-24 from the field.

Defending champions the Lakers have lost five of their past seven games as injuries begin to pile up.

James was listed as probable to play ahead of the Phoenix game with a left ankle sprain suffered earlier in the season.

He will now sit out of the second game of a back-to-back when the Lakers travel to take on the Kings.

After having a rest and receiving some treatment, it is still expected James will play in his 17th straight All-Star Game on Sunday.

With Anthony Davis already ruled out, Kyle Kuzma and Marc Gasol missed out against the Suns.

"We play so well the last two games, we get back into a rhythm, and then we find out [on the day of the game] that two of our big guns were out," James said after the game, per ESPN.

"It is definitely deflating, especially when you were playing poorly [losing four in a row] and then you get in a good rhythm [with two wins]."

Missing time will not sit well with James, who last month insisted he did not believe in rest amid calls for him to be given a breather to cope with a gruelling schedule.

Despite their recent struggles, the Lakers are third in the Western Conference at 24-12, just behind the Suns (23-11).

Lakers coach Frank Vogel added: "I'm happy with how we are competing. 

"Our guys are giving great effort and great hustle and great fight. You understand there is a big picture here, and guys are keeping the big-picture mindset."

The surging Suns won despite an ejection for star shooting guard Devin Booker, who had 17 points before being removed in the third quarter.

Dario Saric had 21 points off the bench, 10 of those coming in the fourth quarter.

James, 36, is averaging 25.8 points, 8.0 rebounds and 7.8 assists per game this season, his third with the Lakers.

All eyes in the NBA will be trained on Houston on Wednesday as the Rockets host James Harden and the Brooklyn Nets.

Harden was an outstanding player with the Rockets, winning the 2018 MVP award and twice reaching the Western Conference Finals, but he is unlikely to receive a warm welcome.

The nine-time All-Star decided in the offseason he wanted to leave Houston and worked to force a trade.

Although the Rockets initially resisted, a blockbuster deal was eventually agreed with the Nets, who pipped the Philadelphia 76ers to the signing.

Harden, slow by his lofty standards in the first eight games of the season in Houston, has rediscovered his best form in the NBA's newest 'big three' with Kyrie Irving and Kevin Durant.

Both the player and his former team, struggling badly at 11-22, will be determined to come out on top in this first meeting since they parted ways.

TOP PERFORMERS

Houston Rockets - John Wall

Even with Harden's numbers declining at the start of 2020-21, no Houston player has been able to match the 24.8 points he scored on average across those eight games.

Christian Wood (22.0) has come closest, yet an ankle injury has limited him to just 17 games. The Rockets have lost 12 in a row since he went down a month ago.

So, Wall, who missed the entirety of the Washington Wizards' 2019-20 campaign with a torn ACL, has had to step into the breach.

Although Houston's form is awful, Wall at least comes into this clash on somewhat of a roll, playing 10 straight games and scoring 32 points last time out against the Cleveland Cavaliers, his best return since December 2018.

Brooklyn Nets - James Harden

Wall is not alone in being asked to do some heavy lifting, as Harden, the third man signed to the 'big three', has operated without either Irving or Durant due to injuries at times in the early stages of his Brooklyn career.

He has done so admirably, however, averaging 25.3 points, 11.3 assists and 8.7 rebounds since leaving the Rockets.

With Irving returning following a back issue against the San Antonio Spurs on Monday, Harden scaled new heights, becoming the first player to post 30 points, 15 assists and 10 rebounds in a game without a single turnover since individual turnovers were first tracked in 1977-78.

It was his seventh triple-double of the season already, a mark he only once passed in Houston colours (22 in 2016-17).
 

KEY BATTLE - CAN HOUSTON GET TO HARDEN?

Irving claimed after the Spurs game there would be "no animosity" and "no tension" in Houston "on the court or about James in my presence or anybody else's presence". That seemed optimistic.

Harden's parting shot at the Rockets, where he claimed to "have done everything that I can", prompted angry responses from Wall and the since-waived DeMarcus Cousins.

Given Wall and Cousins had each been team-mates of Harden for only eight games, it stands to reason that some of his long-standing colleagues might have been even more frustrated.

With the Nets a far superior outfit to the Rockets, the conversation around Harden on the court might prove as interesting as any matchup. The Brooklyn man will have to handle the heat.
 

HEAD TO HEAD

The Rockets have had the better of this series, boasting a 64-32 regular-season record, most recently winning in December 2019 when lifted by 44 points from Harden.

The 31-year-old has a 14-15 record against the Oklahoma City Thunder, his only other former team, averaging 28.2 points.

In Harden's three years with OKC, he was 6-6 against Houston.

James Harden is hopeful he will feel the love on his return to face the Houston Rockets for the first time with the Brooklyn Nets.

The Rockets (11-22) host Harden and the Nets at Toyota Center on Wednesday as they attempt to halt a miserable 12-game losing streak.

Last month Harden apologised for the "drama" surrounding his exit from the Rockets and wished his trade to the Nets could have been a smoother process.

Former NBA MVP Harden moved to the Nets after playing more than eight seasons with Houston and still feels part of the community, which he has been helping in the aftermath of the recent devastating storm in Texas.

"The love and the appreciation that I've given to that city and that I still give to that city, I'm hoping that the favour can be returned," Harden, who rejected a new contract with the Rockets last year, told ESPN.

"[I hope I will be] received with love.

"I thought I would never leave that franchise. I thought I was going to be in Houston, obviously, for the rest of my career. 

"Things happened. I've got different goals, and I've seen a different vision for myself and my career and my family.

"It doesn't change the fact of how I feel about the city. But it just didn't go as well - as smooth - as I planned." 

Perhaps reflecting on J.J. Watt's recent exit from the Houston Texans in the NFL, Harden added: "The communication between myself and the front office got a little shaky. 

"And now I look back at it and I see these other scenarios, other situations that are happening, specifically around other players that are in Houston, in different sports. 

"Their transition is going very smooth and I would've hoped for mine to go that smooth, but it didn't. I am where I am now.

"I feel like I'm a part of the community. Me now being in Brooklyn, it hasn't changed the way I feel about that city and everything it's done for me. 

"So whether it's trying to feed as many people as I can, get water, as much water as I can to the people that need it."

As Houston struggle, the Nets are at 23-13 after winning nine of their last 10, with Harden recording 30 points, 15 assists and 14 rebounds in a dramatic overtime win over the San Antonio Spurs on Monday.

Star trio Harden, Kevin Durant and Kyrie Irving have only played seven games together so far.

"I'm just excited for us, as a whole, to be able to play as many games as we can together because the potential that we have is very, very scary," Harden added.

"We're still just doing whatever it takes to come away with wins. The potential is going to be scarier when [Durant] gets back. But for right now, we're holding it down, and we're coming together as a team."

LeBron James' performance was not enough as defending NBA champions the Los Angeles Lakers lost 114-104 at home to the Phoenix Suns.

James posted a game-high 38 points, but the Lakers still went down to the Suns, who ended the team's run of back-to-back wins on Tuesday.

The Lakers had won 10 of their last 12 games against Phoenix – including sweeping the season series 3-0 last term – but a season-high 21 points from Dario Saric off the bench gave the Suns a rare victory.

Aside from Dennis Schroder (17 points), Talen Horton-Tucker (16 points) and Markieff Morris (12 points), James did not have much support as the Lakers continue to play without injured star Anthony Davis.

With the result, Phoenix extended their winning streak to three games.

Beal makes franchise history, Jokic dominates

Bradley Beal became the fastest player to reach 1,000 points in a season in Washington Wizards history – his 31st game of the campaign, surpassing the 33-game record held by Gilbert Arenas (2006-07) and Bernard King (1990-91). Wizards star Beal had 23 points in Washington's 125-111 loss to the Memphis Grizzlies. Memphis' Ja Morant went off for 35 points and 10 rebounds.

Nikola Jokic produced another masterclass to inspire the Denver Nuggets' 128-97 rout of the Milwaukee Bucks. Jokic put up 37 points, 11 assists and 10 rebounds for his ninth triple-double of the season and 50th of his career – the third-fastest player to the half-century mark in NBA history. A 27-point performance from two-time reigning MVP Giannis Antetokounmpo was not enough to prevent the Bucks from having their five-game winning streak snapped.

Paul George stepped up in the absence of injured team-mate Kawhi Leonard with a game-high 32 points, but the Los Angeles Clippers still lost 117-112 to the Boston Celtics.

Double-doubles from Trae Young (18 points and 10 assists) and Clint Capela (10 point and 17 rebounds) gave the Atlanta Hawks a 94-80 victory over the Miami Heat in Nate McMillan's debut as interim head coach following Lloyd Pierce's exit.

Heat fizzle out

It was a forgettable outing for the Heat in Miami. Their six-game winning streak ended abruptly on the back of a woeful shooting display. Miami shot just 37 per cent from the field, while they were only 27.3 per cent from three-point range. Tyler Herro was three-of-12 shooting as he converted just three of seven attempts from beyond the arc.

LeBron says no!

There was no way past James as he denied Phoenix's Deandre Ayton at the rim in the second quarter on Tuesday.

Tuesday's results

Memphis Grizzlies 125-111 Washington Wizards
Boston Celtics 117-112 Los Angeles Clippers
San Antonio Spurs 119-93 New York Knicks
Atlanta Hawks 94-80 Miami Heat
Denver Nuggets 128-97 Milwaukee Bucks
Phoenix Suns 114-104 Los Angeles Lakers
Detroit Pistons-Toronto Raptors (postponed)

Jazz at 76ers

The NBA-leading Utah Jazz (27-8) will travel to face Eastern Conference pacesetters the Philadelphia 76ers (23-12) in a blockbuster showdown on Wednesday. Both teams are coming off losses.

Toronto Blue Jays recruit George Springer is excited about the team's young core, describing them as "beyond impressive" after making his Spring Training debut.

Springer, who joined the Blue Jays on a six-year, $150million contract via free agency – the largest deal in franchise history, debuted in Tuesday's 4-2 win over the Philadelphia Phillies.

A three-time All-Star and two-time Silver Slugger, Springer managed his first Spring Training hit against the Phillies.

The arrival of MLB World Series champion Springer from the Houston Astros caused a splash, his wealth of postseason experience complimenting a young group of stars in Toronto – Vladimir Guerrero Jr., Lourdes Gurriel Jr., Bo Bichette and Cavan Biggio.

In Toronto, Bichette is the first shortstop in MLB history to have a .300-plus batting average and a .500-plus slugging percentage in each of his first two seasons (minimum 125 plate appearances in both seasons), per Stats Perform.

Blue Jays team-mate Biggio became the first player in league history to have at least 20 home runs, 20 stolen bases and 100 walks through his first 159 career games (that is how many games he has played so far).

As for Guerrero, he is the only MLB player currently 21 or younger who has at least 100 career RBIs.

Based on age at the time of games, the Blue Jays had the most hits (234), runs (148), home runs (38), RBIs (137), XBH (93) and BB (103) in 2020.

"A lot of people will say that they're young, but I think they're advanced for their age," Springer said post-game.

"I was having a conversation and you just kind of realise the talent it takes to play at this level at age 21, 22.

"It's beyond impressive to be in the big leagues that young and to do the things all these guys can do."

Springer impressed on his Spring Training bow for the Blue Jays, who will open their 2021 MLB season against American League (AL) East rivals the New York Yankees on April 1.

Batting leadoff at TD Ballpark on Tuesday, 2017 World Series MVP Springer hit a single as a designated hitter.

"I generally just see the ball and hit the ball," Springer said. "As Spring Training goes along, you're not facing a new guy every inning, you're starting to face the same guy over and over again.

"Sequences are starting to change, the game plans are starting to change, so as the spring progresses, it becomes more of a season-like feel."

Springer leads MLB with 136 home runs from the lead-off spot since 2015. The Blue Jays as a team have 129 homers from the lead-off spot over that time, per Stats Perform.

He has 39 lead-off home runs in his career – fourth most all-time behind Rickey Henderson (73), Ian Kinsler (48) and Brady Anderson (44).

Springer has recorded seven career World Series home runs – most from the lead-off spot all-time – and he is 19-for-56 (.339) in the World Series in his career. No other current Blue Jays player has a World Series hit in their career.

The 31-year-old's 174 home runs since debuting in MLB via Houston are third most by an Astro in a player's first seven career seasons, behind only Jeff Bagwell (187) and Lance Berkman (180).

Blue Jays manager Charlie Montoyo added: "I like when he leads off like we did today. I like that. But we'll see."

San Diego Padres star Fernando Tatis Jr. put on a show with a memorable grand slam in a Spring Training win over the Arizona Diamondbacks.

Tatis is fresh off signing a record-setting extension with the Padres last month – an eye-popping 14-year, $340million contract, which is the longest deal in MLB history and also the largest contract awarded to a player not yet eligible for arbitration.

MLB's new poster boy and the generational superstar teased what is to come in 2021 with a grand slam in the second inning of Tuesday's victory against the Diamondbacks.

Tatis sent the ball 441 feet to left field at Salt River Fields – a home run that went viral on social media.

"Hit it about as clean as you can hit a ball," Padres manager Jayce Tingler said of Tatis, who hit his first career grand slam against the Texas Rangers last season. "That was really, really good to see."

Tatis, who flipped his bat in celebration, also singled in the first inning and then stole second as Trent Grisham was allowed to sprint home.

"Had a couple good defensive plays, great at-bats, did something on the bases," Tingler said. "That's everything you want to see."

Tatis won a Silver Slugger award last season, having hit .277 with 17 home runs and 45 RBIs in the coronavirus-shortened 2020 campaign.

The powerful 22-year-old is the first player in MLB history to have at least 35 home runs and 25 stolen bases within the first 150 games of his career.

Tatis packs a punch with the bat – he led the majors in average exit velocity (95.9 mph), hard hit percentage (62.2), and balls hit 95-plus MPH (102).

He also enjoyed a remarkable rise defensively following an erratic rookie season at shortstop.

Tatis went from minus-13 outs above average (OAA) to plus-seven – his plus-20 improvement the largest of any player across that period.

When it comes to on-base plus slugging, Tatis stacks up well. Since 1920, Tatis (150.8) is only behind Juan Soto (153.9 – 2018-20), Albert Pujols (159.3 – 2001), Jimmie Foxx (160.0 – 1925-29), Ted Williams (161.5 – 1939-40) and Mike Trout (165.0 – 2011-13) for highest OPS-plus up until the age of 21.

Using the same timeframe, but for wins above replacement (WAR) among shortstops, Tatis (5.6) ranks ninth. Alex Rodriguez is top (13.6 – 1994-97).

Andrey Rublev will face Andy Murray at the Rotterdam Open after the Russian battled past Marcos Giron 7-6 (7-1) 6-3.

The appetising showdown between Rublev and former world number one Murray was handed a primetime evening slot on Wednesday's schedule by tournament organisers, given the appeal of a clash between one of the ATP Tour's brightest younger stars and the three-time grand slam winner.

World number eight Rublev is, at the age of 23, among the band of players who have emerged as potential torchbearers for the men's tour once the likes of Murray and the big three of Roger Federer, Rafael Nadal and Novak Djokovic make way.

After wildcard Murray's win over Robin Haase on Monday, Rublev secured victory on Tuesday against 80th-ranked Giron, who earned his place in the ATP 500 tournament through qualifying.

Murray and Rublev have played only once before, in entirely different circumstances to those surrounding Wednesday's match. That previous encounter came at the Australian Open in 2017, with Murray, then ranked number one in the world, scorching to a 6-3 6-0 6-2 win in round two.

The Scot has since undergone major surgery on a hip problem that has threatened to end his career, and heads into his clash with Rublev ranked 123rd in the world but eager to show he can compete at a high level.

"Andy is a true legend and I have a really good connection with him. I really like him as a person and as a player. He destroyed me once in the past. I'm sure we'll have great, long rallies and it will be a fight," Rublev said, quoted via the ATP website.

Australian Open semi-finalist Stefanos Tsitsipas passed his first-round test by scoring a narrow win over a player that beat Murray in Montpellier last week – the second seed and world number six overcoming Belarusian Egor Gerasimov 7-6 (7-4) 7-5.

The tournament lost a three-time grand slam champion when Stan Wawrinka was edged out 6-4 7-5 by Russian Karen Khachanov in a tough first-round matchup for the Swiss, who sits just one place above the Russian at number 20 in the world rankings.

Alex de Minaur beat fellow Australian John Millman 6-1 6-4, while top seed Australian Open runner-up Daniil Medvedev begins his challenge on Wednesday when he tackles Serbian Dusan Lajovic.

Madison Keys is intent on giving Maria Sakkari a second-round test after marking her first WTA Tour appearance since September with a clinical win at the Qatar Open.

American world number 19 Keys, who reached the US Open final in 2017, had not played on tour since losing to Zhang Shuai in the first round of the French Open in late September – she was ruled out of the Australian swing of this season after a positive coronavirus test.

But Keys roared back to action with a thumping 6-4 6-1 victory over Belinda Bencic on Tuesday, the Swiss who last week reached the Adelaide International final.

"I'm really happy with how I came out and played today," Keys said. "I'm a little bit surprised with myself but hoping to keep the momentum going."

Sakkari promises to pose a tricky test for Keys, who is unseeded this week, given the Greek player dropped only three games in her opening win over Mayar Sherif and has shown bright early-season form.

World number 23 Elena Rybakina tripped up in the first round after the Moscow-born Kazakh player lost 7-6 (9-7) 7-6 (7-5) to Germany's 56th-ranked Laura Siegemund at the WTA Premier event.

Jessie Pegula, Anastasia Pavlyuchenkova, Ons Jabeur and Misaki Doi also scored straight-sets victories in Doha.

At the Lyon Open, French players Caroline Garcia and Kristina Mladenovic were both pushed to three sets before inking their places in the last 16.

Third seed Garcia edged compatriot Oceane Dodin 6-2 2-6 6-3, while fourth seed Mladenovic scrambled for a 5-7 7-5 6-2 win over Romanian Mihaela Buzarnescu.

Former Wimbledon runner-up Eugenie Bouchard, in on a wildcard, was bounced out 7-6 (9-7) 6-2 by Aliaksandra Sasnovich, the world number 96 from Belarus.

Toto Wolff admitted Max Verstappen is a driver who will be "on everybody's radar" but has vowed Mercedes will not rush to seduce the Red Bull star.

Mercedes team principal Wolff will be aware that reports have linked Verstappen with a possible future move to the Silver Arrows, possibly as a long-term replacement for Formula One champion Lewis Hamilton.

For now, though, Hamilton is going nowhere, having signed a contract for the upcoming 2021 season, and the British driver may yet remain for years to come.

After landing a seventh drivers' title last year to match Michael Schumacher's F1 record, there is no driver that Mercedes would take above Hamilton in the present time.

Wolff said: "The symbiosis that we have in the relationship, it's always that we have a mutual understanding of what we want to do in the future. That will be also the case in the discussions with Lewis going forward.

"Max is certainly an outstanding young driver that will be on everybody's radar in the future, but we are not flirting outside before we have a clear understanding with our two drivers."

Verstappen has finished third in the championship in each of the last two seasons, with the 23-year-old winning races at Silverstone and Abu Dhabi during the 2020 campaign.

He tallied 214 points to finish just nine points behind Mercedes' runner-up Valtteri Bottas in the championship.

Quoted widely after Mercedes unveiled their new W12 car on Tuesday, Wolff underlined how Mercedes are not blinkered about the team's future and the potential for a change of direction.

Bottas is also due to reach the end of his contract after the new campaign, meaning Mercedes currently have flexibility should they wish to reshape their driver line-up for 2022 and beyond.

"Our first discussions are going to be with Valtteri and Lewis in respecting our values, integrity and loyalty - but on the other side the young drivers are the future," Wolff said.

"Therefore we need to consider how we want to set ourselves up for the years beyond."
