Yadier Molina has agreed to terms on a new deal to extend his St Louis Cardinals career into an 18th MLB season.

The 38-year-old catcher's new contract was announced by the Cardinals on Monday.

Molina made his MLB debut with the Cardinals in 2004 and has gone on to win two World Series with the team, while being named an All-Star nine times.

"We are excited to announce that we have agreed to terms with Yadier Molina on a new contract!" the Cardinals wrote on Twitter.

"We will have more details tomorrow on Yadi continuing his Cardinals legacy."

Reports said Molina, who was a free agent, had agreed to a one-year extension with the Cardinals.

Molina's 2,025 games for the Cardinals ranks as the third most for the team, behind Stan Musial (3,026) and Lou Brock (2,289).

He is sixth for hits (2,001), seventh for RBIs (932), 10th for home runs (160) and 22nd for runs scored (713).

The Cardinals made the MLB playoffs in 2020 before falling to the San Diego Padres in the National League (NL) Wild Card Series.

World number one Novak Djokovic is in favour of technology replacing linespeople across the ATP Tour amid the absence of judges at the Australian Open.

This year's Australian Open is being held without line judges as a response to coronavirus restrictions at Melbourne Park, where "Hawk-Eye Live" technology is being used on every court. 

It is the first grand slam to replace all linespeople with technology as the tournament seeks to limit the number of people on court amid the COVID-19 pandemic.

Djokovic was sensationally disqualified in the fourth round of last year's US Open for inadvertently hitting a ball at a line judge during his clash with Pablo Carreno Busta in New York.

Asked about the situation at the Australian Open, defending champion and eight-time winner Djokovic told reporters: "I think back [at the] US Open last year, someone asked me whether I would support the idea of introducing this kind of line call technology at every tournament.

"Obviously providing that the tournament is able to afford financially that kind of investment, because obviously it is an investment.

"I said that I support that, because I feel, yes, I understand that there is a tradition and history and the way we kind of got used to the line umpires being there, and I think it's nice that there is a lot of people and also volunteers with these line umpires that love tennis and love to have an opportunity to be out on the court and be close to the players and be part of a great event.

"But I think when you draw a line that generally I actually am in favour of technology. I think it's proven to be very accurate in this particular instance.  I don't see a reason why we need the line umpires, to be honest, if we have technology like this. I would of course keep the ball kids, but line calls I'm in favour of this technology."

Djokovic was speaking after beginning his quest for a ninth Australian Open title with a 6-3 6-1 6-2 win over Jeremy Chardy on Monday.

The 17-time grand slam champion is trying to close the gap on 20-time major winners Roger Federer - who is absent from this year's event - and Rafael Nadal.

"I respect all of my opponents' records. I think especially Roger and Rafa, what they have achieved over the years. They are legends of our sport, and I admire them a lot," Djokovic said. "They have positively affected my game and my growth, my development and all my success. Wouldn't be what it is if these two guys were not there.

"I have had tremendous rivalries with these two guys and we still keep on going. But I don't want any of their success, if you know what I mean. I'm not jealous of their success or anything like that. I try to build my own authentic career and my own success, and I stick to that."

Djokovic added: "I am always motivated and inspired to achieve big goals and break records. I would lie if I say that's not, you know, something that I'm thinking about or that my attention is not going that way.

"I have been very transparent about the fact that one of the biggest goals is to try to reach the number one of all time weeks' record, and I'm getting closer and closer to that one. That's a kind of a lifetime achievement for me. 

"Grand slams, as well. Of course the Masters events, I think the 1000 events over the years I have managed to be very consistent and win a lot of titles there. Those are the biggest events that we have on the four other than grand slams.  The head-to-head records with top guys as well, to name a few. I try to be a good student of the game. 

"I'm just very fortunate to be in this situation and position that I'm in at the moment, so I try to keep on going and obviously setting up new goals for myself, because I feel like other than passion and love that I have for the game and the biggest reason why I still play it is exactly that pure emotion that I have of enjoyment when I'm there and excitement.

"As a professional tennis player, I need to have goals. Over the last 15 years, everything that I have managed to achieve, I don't settle for anything less but the top of the men's game and the biggest trophies.  That's something I always aim for. I work towards that.  And yeah, I'm still lucky to be where I am. Let's see what the future holds."

Anthony Davis will miss the Los Angeles Lakers' clash with the Oklahoma City Thunder on Monday due to an Achilles injury.

NBA champions the Lakers listed star Davis as out with tendonosis of his right Achilles tendon.

Davis, coming off a championship-winning season with the Lakers, posted 30 points, five rebounds, three assists and two blocks in the team's 135-129 double-overtime victory against the Detroit Pistons on Saturday.

The 27-year-old is averaging 22.3 points, 8.6 rebounds and 3.2 assists per game for the Lakers this season.

The Lakers (18-6) - in the midst of a four-game winning streak - are second in the Western Conference, behind the in-form Utah Jazz (19-5).

Derrick Rose has been traded to the New York Knicks by the Detroit Pistons in exchange for Dennis Smith Jr, it has been confirmed.

The Pistons also received a 2021 second-round draft pick via the Charlotte Hornets.

In New York, former MVP Rose reunites with Tom Thibodeau, who coached him at the Chicago Bulls and Minnesota Timberwolves.

It is Rose's second stint with the Knicks after the 2016-17 season, when he struggled in the triangle offense during Phil Jackson's reign as president of the franchise. He was subsequently picked up by the Cleveland Cavaliers in free agency following the fourth knee operation of his career.

Rose, who is in the final year of a contract that pays him $7.7million, averaged 17.2 points and 5.2 assists in 65 games for the Pistons, though his performances this season have not lived up to the promise he showed in 2019-20.

Smith made just three appearances for the Knicks in 2020-21 and reportedly volunteered to play in the G League bubble to get more minutes on the floor.

He will hope to avoid that after joining the Pistons, whose 5-18 record is the worst in the NBA.

Uncapped duo George Taylor and Charlie Shiel have been called up to the Scotland squad for the Six Nations clash against Wales along with D'Arcy Rae.

Gregor Townsend drafted in centre Taylor, scrum-half Shiel and prop Rae for the round-two encounter at Murrayfield on Saturday between two sides on a high following winning starts.

Rae earned his only cap against Ireland in 2019, coming off the bench in a 22-13 loss.

Ewan Ashman, Blair Kinghorn, Jamie Dobie and Rufus McLean have been released back to their clubs.

Scotland dominated defending champions England on the opening day of the tournament, ending a 38-year wait for a win at Twickenham with an 11-6 victory on Saturday.

Captain Stuart Hogg said they will remain grounded after regaining the Calcutta Cup.

The full-back, who was named man of the match in the defeat of Eddie Jones' side, said: "We are not going to get ahead of ourselves. We will enjoy this one, no doubt, but then it is on to Wales next week.

"We'll get back on the horse and ready to go because next week is another challenge for us and one we're really excited about."

Naomi Osaka said she was "really nervous" before facing Anastasia Pavlyuchenkova but showed no signs of that as she breezed into the second round of the Australian Open.

Osaka looked dominant on day one of the first grand slam of the year as she welcomed being able to play in front of a crowd at Melbourne Park, taking only 68 minutes to wrap up a 6-1 6-2 victory.

The US Open champion has beaten Pavlyuchenkova three times in a row after losing when they first met in 2017 but was wary of facing the Russian on Rod Laver Arena.

Third seed Osaka said: "I was really nervous coming into this match. I know that I've played her before, and it was really tough. I just wanted to play well.

"The most recent memory I have of playing her was in the Osaka final [that Osaka won 6-2 6-3 in 2019], so it's always really hard to play someone that good in the first round.

"For me, I feel like it might have also helped in a way because I calmed my nerves because I felt like I couldn't afford to be that nervous. But, yeah, it was a tough match."

Serena Williams and Simona Halep stormed into round two, but the 2016 champion Angelique Kerber crashed out with a 6-0 6-4 defeat to world number 63 Bernarda Pera.

Alison Riske and Wang Qiang were the only other seeds to fall, losing to teenager Anastasia Potapova and qualifier Sara Errani respectively, while Bianca Andreescu made a winning comeback.

Williams sisters among major winners to make serene progress

Serena Williams did not look at all troubled by a shoulder problem as she started her latest quest to win a record-equalling 24th major singles title with a 6-1 6-1 demolition of Laura Siegemund.

Her older sister, Venus, also advanced in straight sets, beating Kirsten Flipkens 7-5 6-2.

Iga Swiatek, the French Open champion, was too good for Arantxa Rus, winning 6-1 6-3, and Petra Kvitova got past Greet Minnen 6-3 6-4.

Kerber will not be claiming a fourth major crown this month after falling to Croatia-born American Pera.

Halep planning to oust another Australian

Two-time major winner Halep was a cut above Lizette Cabrera, winning 6-2 6-1 in 59 minutes, and is looking forward to facing another Australia in the second round in the form of Ajla Tomljanovic. 

"I like to be here, so I like to play Australians," Halep quipped.

"I feel good. My body is fit. It's always difficult to play a big hitter. So, I have to be strong on my legs, focus on myself and give my best.

"I expected a tough match because I played against her before and I know how it's gonna be. She's a good opponent, a good player, and I will focus just on myself like I do every time, but I'm ready for a good battle."

Andreescu back in business

Andreescu put her injury woes behind her, battling past Mihaela Buzarnescu 6-2 4-6 6-3 in her first match for 15 months.

The Canadian had not played in a grand slam since winning the US Open in 2019 but was back in business on John Cain Arena.

Eighth seed Andreescu said: "After the match, I sat down with my team a little bit, and I'm like, 'Oh, guys, here we go again, those three-setters' and they just started laughing because they obviously knew what they were getting themselves into.

"But those matches are super good for me in my opinion because it really shows that I can scramble when I really need to, or if there's some pressure I can dig my way through it somehow. When my back is against the wall, not only today, but I've noticed throughout my last couple tournaments in 2019, I've been able to pull through with those."

Serena Williams will win a 24th grand slam singles title despite the mental pressure of trying to match the record having held her back, Ana Ivanovic says.

American Williams breezed into the second round of the Australian Open on Monday with a 6-1 6-1 victory over Laura Siegemund.

She won her 23rd major singles title in Melbourne in 2017, taking her to within one of matching the all-time record held by Margaret Court.

However, she has failed to win any of the following 14 slams, marking the longest span in her professional career without lifting any of the four biggest trophies.

Williams has won 22 of her majors over the last two decades, at least 15 more than any other women's player in that time, but her most recent four slam finals have ended in defeat.

Ivanovic, the former world number one who reached the final in Melbourne in 2008, wonders if the significance of matching Court's tally may have added extra pressure on Williams.

However, she remains convinced the 39-year-old will claim another title, telling Stats Perform News: "Yeah, definitely after winning so many grand slams, you still have it and especially [as] she reached so many finals, even though she didn't win a title.

"So, I think it's just a matter of, she proved that she can win matches and she can get a part in the grand slams.

"I think she wants to go further for the record. So I think that's maybe a bigger issue than just winning a title. So, it's both a little bit, I guess mental as well. But I'm sure she can do that. And I'm sure that's why she's there and still pushing and still being on top of the game after so many years."

"She's definitely an icon and a very, very powerful player. And I remember you know, when I played against her, she's very intimidating because her serve is just very, very strong. Her shots are very strong. So you feel like you have to attack and move forward otherwise you don't really have a chance. It was very inspiring to play against her and to play against someone who reached so much in women's sport. I think she will go [down] in history. Definitely."

Reigning champion Sofia Kenin begins her Australian Open defence against home hope Maddison Inglis on Tuesday.

The 22-year-old is hoping to become the first women's player to win successive Australian Opens since Victoria Azarenka back in 2013.

Kenin was a finalist at the French Open last year after winning in Melbourne, having failed even to reach the last eight in her first 11 majors, but she was beaten in straight sets by Garbine Muguruza in the quarter-finals of the Yarra Valley Classic warm-up tournament.

"She seemed very, very solid and very consistent lately, so of course she has a big chance but, like I said, it's so difficult to talk because you don't see the players playing, you don't see what kind of form they're on and how the last months have been for them," said Ivanovic.

"And you know, without competition for so long again, it definitely is going to [have an] affect but she can indeed [win]. One Australian Open and then she went on to the French Open final, so she's definitely been very, very consistent and she's going to I think try to go again.

"I think that's why it's very hard to predict who will be the winner of a grand slam, especially on the women's side. But on the other hand, it's nice to see new faces and new players coming up, and it also brings new excitement to the tour."

Ivanovic also tipped French Open champion Iga Swiatek to challenge in the latter stages, adding: "I do like Iga Swiatek and the way she plays. I like her aggressive game. I like the fact that she runs around and hits her forehead, it was kind of the style that I had. So I really hope she can keep up the work that she did last year and continue to do well."

Lewis Hamilton has signed a new contract to race for Mercedes in the 2021 Formula One season, it has been confirmed.

The reigning F1 champion will spend a ninth season with the Silver Arrows after winning a record-equalling seventh drivers' title in 2020.

Mercedes and Hamilton have agreed a deal that includes the formation of a joint charitable foundation with the aim of supporting greater diversity and inclusion in Motorsport.

Hamilton said: "I am excited to be heading into my ninth season with my Mercedes team-mates. Our team has achieved incredible things together and we look forward to building on our success even further, while continuously looking to improve, both on and off the track.

"I'm equally determined to continue the journey we started to make motorsport more diverse for future generations and I am grateful that Mercedes has been extremely supportive of my call to address this issue.

"I'm proud to say we are taking that effort further this year by launching a foundation dedicated to diversity and inclusion in the sport. I am inspired by all that we can build together and can't wait to get back on the track in March."

Team principal Toto Wolff added: "We have always been aligned with Lewis that we would continue, but the very unusual year we had in 2020 meant it took some time to finish the process.

"Together, we have decided to extend the sporting relationship for another season and to begin a longer-term project to take the next step in our shared commitment to greater diversity within our sport.

"Lewis' competitive record stands alongside the best the sports world has ever seen, and he is a valued ambassador for our brand and our partners.

"The story of Mercedes and Lewis has written itself into the history books of our sport over the past eight seasons, and we are hungry to compete and to add more chapters to it."

In a 2020 season that was truncated due to the coronavirus pandemic, Hamilton still made history by breaking Michael Schumacher's all-time F1 wins record with his 92nd victory at the Portugal Grand Prix.

This year he will hope to surpass Schumacher and become the first F1 driver in history to win eight world titles.

The 2021 season is scheduled to get under way with the Bahrain Grand Prix on March 28.

Novak Djokovic began his quest for a ninth Australian Open title with a convincing straight-sets win over Jeremy Chardy.

The reigning champion and world number one looked in ruthless form as he won 6-3 6-1 6-2 in a little over an hour and a half.

Djokovic, who beat Dominic Thiem in a five-set thriller in the 2020 final, was in an authoritative mood as he took the first two sets in just 56 minutes.

Chardy, whose best grand slam result was reaching the quarter-finals in Melbourne in 2013, offered some valiant resistance in game five of the third set before Djokovic eventually claimed the crucial double break.

The 17-time major winner eased through the final two games in front of a jubilant crowd, finishing with back-to-back aces to set up a second-round match with Frances Tiafoe.

"It makes my heart full to see the crowd in a stadium again," said Djokovic, who has reached at least the semi-final stage in seven of his previous nine majors.

"There's an ongoing love affair between me and the Rod Laver Arena. It's definitely one of the most special courts on the tennis tour around the world and my most successful. Every time I step on this court, I relive those memories."

Djokovic's preparations for the tournament were overshadowed by a row over quarantine conditions for players arriving in Australia, the 33-year-old having lobbied Tennis Australia and state authorities to loosen restrictions for 72 players who had to spend two weeks in their hotel rooms.

There was little about his performance on Monday to suggest any distractions from the task at hand, although he bristled a little in the on-court interview when it was put to him he had been "frustrated" in recent weeks.

"I'm just really glad we're free, playing tennis, back in Australia," he then said. "It's a happy place for us, a happy slam."

Data Slam: Djokovic at his clinical best

Djokovic dropped just nine points on serve and hit 41 winners to just 11 unforced errors, sending down nine aces and one double fault.

Such imperious play left Chardy, who had lost all 13 of their previous encounters, with little chance of an upset.

WINNERS/UNFORCED ERRORS
Djokovic – 41/11
Chardy – 20/26

ACES/DOUBLE FAULTS
Djokovic – 9/1
Chardy – 3/3

BREAK POINTS WON
Djokovic – 6/13
Chardy – 0/0

Lewis Hamilton has signed a new contract to race for Mercedes in the 2021 Formula One season, it has been confirmed.

Serena Williams took inspiration from the "unbelievable" Tom Brady as she cruised into the second round of the Australian Open with a "vintage" performance.

Brady made yet more history on Sunday, the most successful player in NFL history winning a seventh Super Bowl as the Tampa Bay Buccaneers beat the Kansas City Chiefs 31-9.

The incredible Brady, 43, showed age is no barrier, throwing three touchdown passes – two of which were scored by his long-time friend Rob Gronkowski – and completing 21 of 29 throws for 201 yards.

Brady did now allow any interceptions as he picked up the MVP award at Raymond James Stadium.

Williams started her quest for a record-equalling 24th grand slam singles title with a 6-1 6-1 defeat of Laura Siegemund on Monday, then paid tribute to her fellow American Brady.

She said of his exploits: "It's unbelievable. I just was watching as much as I could to see. My only word is it's unbelievable. I kept saying: 'This is unbelievable, this is unreal'.

"You can't say it was the system he was at formerly [the New England Patriots]. It's definitely Tom Brady, he's Tom Brady. He's amazing."

Brady banished everyone from his house in the days leading up to the Super Bowl so he could fully focus on inspiring the Buccaneers to victory, but the 39-year-old Williams said she could never do the same as she would not want to be separated from her daughter, Olympia.

"I would not be able to go function without my three-year-old around," Williams said. "I think I would be in a depression.

"We've been together every day of her life, so... Is that healthy? Not at all! Not even close. But every single day I just want to be around her. It's great. Everyone's different.

"I can totally understand why he would banish because if I had the strength to do it, I would too.

"I could see it's definitely a distraction, especially every year that I've played except for the past few months, I finally am starting to get better at it. The first two and a half years was very difficult. I wasn't strong enough to do the banishment."

Williams, who will face Nina Stojanovic in the second round at Melbourne Park, was delighted with the manner in which she swept Siegemund aside and had no issues with her shoulder after withdrawing from a pre-tournament event citing an injury problem.

"This was a good start. Definitely vintage 'Rena'. It's definitely good. I think I'm pretty good at pacing myself in a grand slam," she said.

"I was happy just to get through it. Wasn't sure how my serve would be after a little bit of that shoulder, but it's feeling good, I'm feeling good. So, it felt really good.

"Last year was very crazy for the world, and to be able to do what I love and to be able to come out and compete and play at a grand slam, after the last 12 months, it makes me appreciate the moment even more."
