South Africa will be hoping some fresh faces can lead to a change in fortunes in Pakistan as the two nations switch focus to the Twenty20 format. 

Lahore will stage all three matches in the series, which comes after Pakistan recorded a 2-0 sweep over the same opponents in Test action. 

However, many of the Proteas who featured in that series are not involved in the T20 fixtures, including captain Quinton de Kock. 

Heinrich Klaasen is instead in charge for the tourists, while Dwaine Pretorius, Lutho Sipamla, Tabraiz Shamsi and George Linde are the only members of the squad who have stayed on after Test duty. 

The stand-in skipper insists that while South Africa may be lacking in experience, those on duty are determined to seize the opportunities that come their way during the trip. 

"South Africa has got loads of talent, which people sometimes don't see because we only have six franchises," Klaasen said. "We are by no means a second-string T20 squad, and we are looking to win." 

Klaasen revealed he is now "fit and safe" after overcoming COVID-19, though it took a heavy toll on him physically. He put up an Instagram post during his recovery to make clear the effects of the virus, in which he wrote: "Covid is real and didn't think it would be this hard to come back". 

As for Pakistan, they have named a 20-man squad that includes four uncapped players but is missing Mohammad Hafeez, who failed to come to an agreement over the date he was to enter the group's bio-secure bubble. 

Fakhar Zaman and Wahab Riaz are also notable absentees having been dropped, while Shadab Khan is ruled out through injury. 

Zafar Gohar, Danish Aziz, Zahid Mehmood and Amad Butt are the quartet of new faces, while Hasan Ali – the hero for the hosts in the second Test with 10 wickets in the match – is back involved again in the shortest format.

Pakistan go into the opening game on Thursday having won 14 of their previous 18 T20 matches on home soil (L4), including the last five in a row.

Babar right up there with the best

No matter what the format, Babar Azam is crucial to Pakistan. The right-handed batsman has scored the most amount of runs in T20 cricket at international level since the start of 2018, managing 1,213 across his 28 innings at an average of 52.7.

After a relatively quiet Test series in terms of his individual output, Babar will be eager to capitalise on a new-look South African attack that is without the services of pace trio Kagiso Rabada, Anrich Nortje and Lungi Ngidi.

Positive spin to help Proteas

Shamsi is one of the few who has remained for the T20 series; the left-arm wrist spinner was ruled out of the first Test with a back injury and then did not feature in the second match.

The 30-year-old has played in 25 T20 games for South Africa, taking 21 wickets at 33.33 with an economy rate of 7.69 runs per over, and has the chance to become a pivotal member of the XI, particularly with a World Cup in the format to come in India later this year.

Key series facts

- South Africa have never lost a multi-game bilateral T20 series in Asia, winning five times out of a possible six in the continent (D1).
- Since the start of 2018, Pakistan wicketkeeper Sarfaraz Ahmed (18 catches and five stumpings) has been directly involved in the joint-most T20 dismissals among those featuring for a Test-playing nation (23 – level with Alex Carey and Tim Seifert).
- Since the start of 2018, Babar Azam has scored the most runs in the T20 format, managing 1,213 runs across his 28 innings at an average of 52.7.
- Only David Miller from the current Proteas squad has played a T20 international game in Pakistan, having represented the World XI in 2017. He has logged 20 catches in the format since the start of 2018, the third-most of those to feature for a Test-playing nation.
- Faheem Ashraf recorded more dot balls than any other player during the T20 series against New Zealand in December 2020). He has only been able to claim four wickets at an average of 41.3 in Pakistan, however.

Novak Djokovic admitted there was plenty of room for improvement after coming through a "difficult spot" at the Australian Open, where Nick Kyrgios thrilled the crowd with an impressive comeback.

Top seed Djokovic was made to work for his 6-3 6-7 (7-3) 7-6 (7-2) 6-3 triumph against Frances Tiafoe as he reached the third round in Melbourne. 

Kyrgios is also through, albeit he even surprised himself by rallying from the brink of defeat to knock out 29th seed Ugo Humbert in the evening session. 

Stan Wawrinka was on the wrong of an upset on Wednesday, but there were no such problems for fellow seeds Dominic Thiem, Alexander Zverev, Diego Schwartzman and Milos Raonic. 

Meanwhile, Denis Shapovalov and Felix Auger-Aliassime will have to put their friendship to one side when they face each other next, the former setting up the all-Canadian clash by beating Bernard Tomic in three sets.

'PASSIVE' DJOKOVIC STILL MAKING PROGRESS

In the first meeting between the pair, the impressive Tiafoe went toe-to-toe with Djokovic on Rod Laver Arena.  

The 23-year-old American's performance – coupled with the Melbourne heat – made the eight-time Australian Open champion sweat, albeit Djokovic felt he could have made life easier for himself.

"I was at times not feeling my timing as well as I normally am. Credit to him. I think he has managed to come out with a great performance and quality of tennis. He put me in a difficult spot," he said. 

"I had my chances early in the second set. If I broke him there, maybe the course of the match would be different.   

"But again, he was holding his serve very well. I was not really using my break-point chances very well. At times I was too passive. Just wasn't feeling the ball today as well as I normally do." 

Next up for Djokovic is another player from the United States in the form of Taylor Fritz, who ousted compatriot Reilly Opelka in a five-set battle.

IN THE NICK OF TIME

Kyrgios described his clash with Humbert as "one of the craziest matches I've ever played" after prevailing 5-7 6-4 3-6 7-6 (7-2) 6-4 - much to the delight of an enthralled audience who watched the drama unfold on John Cain Arena.

The Australian smashed a racket, lost his cool with umpire Marijana Veljovic over a faulty net cord sensor and had to save a pair of match points before eventually coming out on top in a see-saw battle.

"I just remember, down that end, when I was a couple of match points down, I don't know what was going on," Kyrgios - who dropped to his knees after sealing victory - said in his on-court interview.

"If you were inside my head, there were some dark thoughts in there. But I live to fight another day and hopefully I can continue to play good tennis in front of you guys."

His reward is a clash with Thiem, the third seed having dismissed the challenge of German Dominik Koepfer in straight sets as he dropped just six games.

STAN-D AND DELIVER

Wawrinka appeared on course to survive a serious scare when he rallied from two sets down against Marton Fucsovics, but the Swiss was unable to seize on the chances that came his way in a tense tie-break. 

Fucsovics had needed over four hours to overcome wild card Marc Polmans in the previous round and, once again, found a way to get over the finishing line at the end of a Melbourne marathon. 

The Hungarian trailed 6-1 during the decisive breaker, yet hit back to stun the 17th seed 7-5 6-1 4-6 2-6 7-6 (11-9). For Wawrinka, there was frustration at the missed opportunities, albeit he also praised his conqueror. 
  
"From 6-1 up, I started to hesitate a little bit in the way I was playing," he said. "I wanted to put the ball maybe too much in and I [was] not going completely for my shots and that's when I started to miss a little bit and it helped him to come back in the match.  

"He was fighting well, he's a tough player, he's a good player and he deserved to win." 

Real Madrid great Enrique Perez Diaz, better known as Pachin, has died at the age of 82.

The Spanish giants confirmed the news of the former defender's passing on Wednesday.

Pachin made 218 appearances for Madrid between 1959 and 1968 and was part of one of the club's most successful periods.

He won two European Cups, one Intercontinental Cup, seven LaLiga titles and one Spanish Super Cup across his nine years at the Santiago Bernabeu.

Madrid paid tribute to the eight-cap Spain international on their official website.

A statement read: "Real Madrid would like to express its condolences and its warmth and sympathy to his wife Mercedes, his daughters Cristina and Mercedes, his grandchildren Javier and Cristina and all his relatives and loved ones.

"Real Madrid, the club to which he was associated with throughout his life, extends its condolences to all of Madridismo."

Pachin also represented Gimnastica, Burgos, Osasuna, Real Betis and Toluca during his playing days, before a lengthy coaching career that saw him manage 12 different teams, including Madrid's youth side.

Serena Williams and Naomi Osaka sizzled in the scorching Melbourne heat on day three of the Australian Open. 

Williams, aiming once more for a record-equalling 24th singles grand slam, made serene progress from round two on what was the hottest day of the tournament so far. 

It was a similar story for Osaka, who is aiming to become a two-time champion at Melbourne Park, but Simona Halep had to dig deep while Bianca Andreescu and Petra Kvitova were early casualties on Wednesday.

PLAIN SAILING FOR SERENA AND OSAKA

Williams' perfect start to the season extended to 5-0 as she swatted aside Nina Stojanovic 6-3 6-0 to set up a round-three meeting with Anastasia Potapova – the same opponent she overcame in Melbourne in the first round a year ago. 

The seven-time Australian Open champion is looking forward to renewing acquaintances with the Russian. 

"It's always a fun, interesting match [against Potapova]. I'm gonna go home, get ready and just do the best," she said.  

"We're all out here to have fun and I'm happy to be out here, and just to be playing in front of crowd again is really cool. So every day is just fun." 

Osaka, the current US Open champion and the winner in Melbourne two years ago, hammered former world number four Caroline Garcia 6-2 6-3 on Rod Laver Arena in the evening session. 

The Japanese star is set to face her friend Ons Jabeur for the first time in an official match in round three. 

"She's really funny," Osaka said of her next opponent. "I don't know if you guys watch any of her interviews. I think she is really funny and nice.  

"I think the match I am going to play against her will be really difficult, but I'm looking forward to it." 

HALEP SURVIVES TOMLJANOVIC TEST

In contrast to Williams and Osaka's comfortable wins, second seed Halep was taken to the brink by home favourite Ajla Tomljanovic, who won the first set and was serving for the match in the third. 

However, 2018 finalist Halep broke back when trailing 5-4 in the decider and battled through with a 4-6 6-4 7-5 victory in a match that saw a combined 94 unforced errors (57 for Tomljanovic, 37 for Halep). 

"I was expecting that she would play very hard and very strong. I expected it to be a difficult match, but it was more than I thought. But I'm really happy that I can smile now," Halep said.  

"I was not that positive when I was talking to myself. I didn't talk about the score, I was just blaming myself, that I'm not strong enough to win against her. But in the end mentally I was maybe a bit stronger than her, and I didn't want to give up." 

Last year's losing finalist Garbine Muguruza (14) was too good for Ludmilla Samsonova in a 6-3 6-1 win, while French Open champion Iga Swiatek (15) dispatched Camila Giorgi 6-2 6-4. 

Aryna Sabalenka (7), Marketa Vondrousova (19) and Veronika Kudermetova (32) all made it through, but fellow seed Elena Rybakina (17) was beaten in straight sets by Fiona Ferro.

EARLY EXITS FOR ANDREESCU AND KVITOVA

Andreescu became the latest scalp for veteran Hsieh Su-Wei, who earned a commanding 6-3 6-2 victory and is now 4-3 against top-10 players in the slams since 2017. 

Eighth seed Andreescu won the US Open in 2019 but missed the entirety of last year with a knee injury, while her preparation here was disrupted by spending 14 days in quarantine after her coach tested positive for coronavirus. 

"After my first round, I thought I would feel more exhausted, but I felt amazing. Also, today the weather was a bit tricky. Being in the heart of quarantine I could have had those extra two weeks of like being in the heat and getting used to sweating and all of that," she said. 

Next up for Hsieh is Sara Errani, who defeated Venus Williams 6-1 6-0. The veteran American rolled her ankle towards the end of the first set and, despite needing two medical timeouts, valiantly saw out the match. 

Kvitova was a runner-up to Osaka in 2019 and appeared on course to recovery after dominating the second set against Sorana Cirstea. 

But amid sweltering conditions, the Czech ninth seed went on to lose the decider. 

"It was quite a rollercoaster, for sure," she said. "Unfortunately I couldn't take the chances to win the first set.  

"I think that was really the key of the match. She really had a great day today; she played a good game. I didn't really bring the best tennis today. It's really hurting."

Manchester United's players must demand success of each other in order to win their first silverware under Ole Gunnar Solskjaer, according to captain Harry Maguire. 

Solskjaer's side advanced through to the quarter-finals of the FA Cup on Tuesday, recording a 1-0 extra-time win over West Ham thanks to Scott McTominay's strike. 

It was the Scotland international's seventh goal in 30 appearances for the club this season - as many as he managed in 84 outings in previous campaigns. 

United also have a Europa League last-32 tie with Real Sociedad to come later this month and are five points behind leaders Manchester City in the Premier League, albeit having played a game more. 

After reaching the semi-finals of three competitions last season, as well as losing at the same stage to City in the EFL Cup last month, Maguire is determined to get over the line this time around. 

"Last season, it was disappointing to lose in the semi-finals like we did, but we've got to win trophies," he told MUTV. 

"We've got to demand that of each other. We do. We demand that we win trophies and it's vital the team starts winning trophies, for the club and the fans as well."

United's clean sheet against West Ham was their sixth in 10 matches and Maguire felt his side were good value for the win at Old Trafford. 

"We got there in the end and we deserved it," he said. "We felt comfortable on the pitch.  

"I felt in the first half we played with intensity and dominated the game, played the game in their half and had chances where we should be one, two, three up." 

Victory for United was the ideal response to Saturday's 3-3 league draw with Everton, a defensive display Maguire concedes cannot be repeated. 

"When we've conceded, we've conceded too many - when we concede one it seems to be two. It was three against Everton. That's not good enough for this club,” he said. 

"We were disappointed at the weekend. We felt we deserved the three points but we couldn't feel sorry for ourselves.  

"We knew we had to come here tonight and bounce back and get that momentum back on our side ready for Sunday [against West Brom]." 

The Red Devils have won their last nine FA Cup matches at Old Trafford - their joint-longest home winning run in the competition, equalling their nine in a row between 1908 and 1912. Maguire is hoping they will get to play at their own ground again when the draw for the last eight is made on Thursday. 

"Yes, of course. We love playing at this ground, and we've got to make it tough for people to come here and get results," he said.  

"We need to get better and we seem to have improved a little of late. But no, obviously, we want a home game. 

"We fancy our chances against anyone. We just need to look after ourselves, perform well and assure that we start winning trophies at this club."

Western Sydney Wanderers triumphed 2-0 over struggling Melbourne Victory on Wednesday to record their first home win of the A-League season.  

A tight contest was cracked open when Melbourne substitute Rudy Gestede caught Bernie Ibini with a high challenge inside the penalty area.  

Wanderers captain Graham Dorrans converted from the spot to put the hosts ahead in the 72nd minute, though they were made to wait for a second that would wrap up the victory.  

Ibini was involved again when it eventually arrived, carrying the ball from deep to set up substitute Kwame Yeboah to fire beyond Max Crocombe and secure his side all three points at Bankwest Stadium. 

The result lifts Western Sydney up to third in the standings, level on points with second place Brisbane Roar - who have played a game less - and three behind table-topping Central Coast Mariners. 

Melbourne, meanwhile, remain stuck at the bottom having won just once in six outings. Another failure to score on the road means they have managed only two away goals this term, the lowest number by any team in the competition.

Kyrie Irving accepts the Brooklyn Nets "look very average" but insisted the rest of the NBA will be on notice when the team finally starts to click. 

The Nets have assembled a star-studded cast with James Harden arriving last month to form an exciting 'Big 3' alongside Irving and Kevin Durant. 

But since Harden's heralded arrival, the Nets have gone 7-6. Tuesday's disappointing 122-111 loss to the Detroit Pistons was their third in a row and they have a 14-12 record for the season, comfortably behind Eastern Conference rivals the Philadelphia 76ers (18-7) and the Milwaukee Bucks (16-8). 

Defense has been a particular concern for the inconsistent Nets, a fact highlighted by the Pistons shooting 56 per cent from the field and 44.8 per cent from the beyond the arc. 

Irving knows the Nets, who were without Durant against the Pistons, are not living up to expectations but remains confident they will get it right as the season progresses.

"I don't think that we go out every single day and sacrifice the time to be average at anything," Irving told reporters.  

"We look very average, we have the talent that the eye test presents that we should be dominating. We have the experience in terms of some of our guys have been some through certain things, circumstances to be able to battle through. 

"We're the team that is literally battling against so many odds that at this point it's not even a reason to continue to comment on. They are what they are.  

"As a warrior that I am and the energy I have alongside my team-mates, we just have to turn that corner. We haven't done it yet but we will and I'm telling you the league is going to be on notice when that happens. We just have to take it by day by day."

The Nets have lost four of their past five outings, with three of those setbacks coming against teams who have losing records. 

Irving acknowledges the Nets need to address the perception the team is not playing hard enough. 

"I don't accept that, and I don't think our team accepts it as a whole, obviously we don't want that to be what teams think of us," he added.  

"We're seeing it day in, day out where guys and teams are coming out and punching us in the mouth early and we're playing catch up. 

"It happens to be against the guys with the least good records. We gotta call it for what it is, we gotta fix that. It takes maturity, accountability and a realisation of what we need to do moving forward." 

Irving missed the previous loss to the Philadelphia 76ers due to an injury to his right index finger – an issue that is still troubling him. 

"It sucks man," he said. "It's uncomfortable but at the same time I don't want to make excuses. 

"I'm out there, I do a lot of treatment on it, we're down a few players obviously as well. You just want to go out there and compete and worry about the pain later. I'm doing the best I can."

Stephen Curry dazzled once again as he scored 32 points for the Golden State Warriors on Tuesday, leading Steve Kerr to declare: "I don't think I've ever seen him look better". 

Having missed the majority of the previous season due to injury, Curry has been outstanding upon his return. The guard is averaging 29.6 points per game despite playing restricted minutes following his long lay-off.  

The San Antonio Spurs were the latest team unable to stop the two-time NBA MVP, who produced one particularly memorable play in the first quarter of his team's 114-91 triumph on the road.  

Curry was fouled on a drive but, with his back to the basket, managed to flip the ball on target at the last moment, having appeared set at one moment to throw a pass out to a waiting team-mate.  

For Golden State coach Kerr, it was another example of how the 32-year-old makes the seemingly impossible look easy. 

"I think that's part of Steph's brilliance is that he just constantly amazes you to the point where you almost take it for granted," Kerr said after the win over the Spurs.   

"I do think, and maybe it's circumstantial given the injuries and the fact that he's playing with a different group of guys, that this is the best I've ever seen him just from a confidence and a strength standpoint.  

"That's saying something, obviously - a two-time MVP. I don't think I've ever seen him look better." 

Draymond Green compared Curry's miracle shot to one produced by the great Michael Jordan, though the scorer himself insisted it was simply a case of reacting to the situation, having realised he had drawn the foul.  

"It was a fun one," Curry said after the game. "I don't know the ranking, but it was up there, for sure.   

"I had to improvise. I don't really even know how to explain it: I just had a good flow once I got the contact and heard the whistle. Just get it up on the glass however you can. All the wild and acrobatic shots you practice or tried, the instincts take over, so that was pretty cool."  

Curry's performance - he went 11-for-20 shooting from the floor - helped put an end to the Spurs' three-game winning streak, while the Warriors improve to 13-12 on the season.  

The result also saw Kerr reach a significant landmark in his coaching career, with this his 350th win. 

"I worked my butt off over the offseason," Curry said. "I'm just happy to be playing. I feel strong. I feel in rhythm, in ultimate control of my game. Shots are falling.   

"It all comes not only with my own confidence, but growing confidence in my team."

Julen Lopetegui wasn't instantly won over by Jules Kounde following his 2019 arrival at Sevilla from Bordeaux, unlikely as that seems currently.

He had only made four LaLiga starts by the end of October in his first season, and although that was followed by a more prolonged run in the team, a rocky performance against Osasuna in December saw him back on the bench.

As it was, Osasuna weren't able to punish Kounde's struggles on that occasion – the closest they came was hitting the post after his misjudgement of a bouncing ball led to a clear opportunity.

He was withdrawn soon after and only made another two league starts – a defeat at Real Madrid and underwhelming 1-1 home draw with Deportivo Alaves – before the start of February.

Indeed, it arguably wasn't until LaLiga's resumption after the coronavirus lockdown that Kounde truly nailed down a place and found genuine consistency in his performances, but now he is probably the first name on the team sheet.

Sevilla's 'selling club' business model is no secret, and by that logic it is unlikely that Kounde will remain at the Ramon Sanchez Pizjuan long-term – after all, Manchester City were keen in pre-season.

In years gone by Barcelona would've been not only a likely destination for him such has been their affinity for Sevilla-developed talent, it would have also been a stylistically ideal place for him to play. But ahead of the two teams' Copa del Rey semi-final tie, the archetypal Barca defender appears to be well out of their reach financially.

The 'false right-back'

In 2006, two years before he came Barcelona coach, Pep Guardiola wrote a column for El Pais in which he discussed what has become known as the 'Lavolpiana build-up', a defensive setup attributed to Argentinian coach Ricardo La Volpe that essentially demands centre-backs carry the ball forward.

While La Volpe's Mexico side used a back three, the key ball-playing and forward-thinking elements of this system are still evident in the four-man defensive structure at Guardiola's City now – it is also identifiable in Lopetegui's Sevilla.

Kounde is a massive part of that, with the young Frenchman a fine player technically, both on the ball and when distributing.

The attack-minded nature of Sevilla right-back Jesus Navas leaves a lot of space for Kounde to operate in, and he often helps create overloads on the right flank – his positional map shows how he essentially works as a secondary right-back when in possession, while Fernando drops back into central defence to form a back three.

The recent 3-0 win over Getafe show this perfectly, with Kounde almost spending as much time in the attacking half as he did his own.

While the 'Lavolpiana build up' is a risky strategy, the right players can ensure it brings greater incisiveness particularly when playing through a press, and Sevilla have clearly adapted well – they are one of just two teams to not concede a goal as a result of a high turnover this term.

At no point this season has Sevilla's ability to play through the press been more prevalent than when remarkably stringing together 37 passes leading up to Luuk de Jong's second goal in the 3-0 Copa win over Valencia last month. Kounde more than played his role in that.

The defensive playmaker

This setup suits Kounde down to the ground. It's no wonder City were interested in him before going for Ruben Dias, and by extension he would clearly suit the ethos cultivated at Barcelona.

In 2019-20, Kounde showed glimpses of his undoubted ability but it was his partner Diego Carlos who arguably attracted more acclaim.

But this season, building on his positive development post-lockdown last term, Kounde has stepped things up a notch and seemingly relished that forward-thinking ball-playing role.

That is most notable with respect to how often he has carried the ball – his 331 carries (defined as a movement of five metres or more in possession of the ball) is bettered by only six players in LaLiga this term, three of whom are Frenkie de Jong, Lionel Messi and Luka Modric.

Of those 331 carries, 205 have been progressive, so moving Sevilla up the pitch. This gives him another very high ranking, with Pau Torres (321), De Jong (288), Messi (252) and Raul Albiol (246) the four individuals to boast more.

Kounde ranks in the top 10 for several other carry-related metrics – last season he did not. In fact, his 338 carries in 2019-20 is only seven more than he has in 2020-21, which in itself highlights his development.

But his forward runs in possession aren't Kounde's only way of getting on the front foot. His passing is also very positive.

Possessional stats can often be skewed for centre-backs given many of the passes they make are simple short balls to their defensive colleagues, but Kounde is often looking ahead.

His 387 successful forward passes is more than anyone else in LaLiga, while his 486 attempted forward balls is second only to Torres (502), who has played 360 minutes more than Kounde.

The Sevilla talent's 79.6 per cent completion rate from such passes is also better than Torres' 74.5 per cent.

Kounde is a prime example of how centre-backs can be just as satisfying to see in possession as your classic playmakers – in fact, that is essentially what he has developed into, a defensive playmaker of the ilk who wouldn't have looked out of place in the great Barcelona teams of the past 14 years.

While Sevilla and Lopetegui remain the perfect fit for Kounde, it is surely only a matter of time before his €80million release clause no longer appears a daunting figure for certain clubs – though Barca's perilous financial position means they won't be in the hunt.

He's come a long way from that shaky night in Pamplona.

Defending champion Novak Djokovic survived a stern test after prevailing 6-3 6-7 (3-7) 7-6 (7-2) 6-3 against Frances Tiafoe en route to the Australian Open third round.

Tiafoe threatened an upset in warm and sunny conditions at Melbourne Park, where world number one Djokovic was pushed to the limit on Wednesday.

But Djokovic dug deep to prevail in a hard-fought battle, keeping his bid alive for a record-extending ninth Australian Open crown and an 18th grand slam title.

Djokovic had only ever lost in the second round of the Australian Open on one previous occasion - in 2017, when he was upstaged by wildcard Denis Istomin in his earliest Melbourne Park exit since the opening round in 2006.

But Djokovic controlled proceedings initially, despite a blip in the first set against Tiafoe, who enjoyed his best run in Melbourne after reaching the Australian Open quarter-finals two years ago.

After racing out to a 4-1 lead, Djokovic was broken to love in the seventh game as Tiafoe reeled off back-to-back games, only to break back immediately - letting out a thunderous roar before closing out the first set in just over half-an-hour.

Not overawed, Tiafoe refused to go away, rallying from love-40 down and saving three break points in a marathon third game lasting almost eight minutes.

It set the tone for a tense second set as Tiafoe - who saw his winner count rise from five in the opening set to 17 - won a tie-breaker.

Djokovic owned a 15-4 record when splitting the opening two sets at the Australian Open, and 68-16 across majors, and he managed to claim an early break that he consolidated for a 3-0 lead to start the third set.

Tiafoe saved two set points when down 5-4 and he continued to frustrate Djokovic en route to another tie-break, but the latter prevailed, albeit unconvincingly.

The fourth set followed a similar theme until Tiafoe came unstuck at 4-3, Djokovic performing when it mattered most as he secured his passage on the back of a double-fault.

Data Slam: Djokovic dazzles from the service line

The Serbian star was always going to be hard to beat behind a strong serving display. Djokovic fired down 26 aces and won 84 per cent of his first serves, having served sat 62 per cent through the contest.

WINNERS/UNFORCED ERRORS
Djokovic – 56/37
Tiafoe – 49/43

ACES/DOUBLE FAULTS
Djokovic – 26/5
Tiafoe – 23/8

BREAK POINTS WON
Djokovic – 5/14
Tiafoe – 2/3

Former Australian Open champion Stan Wawrinka exited in the second round after a marathon loss to Marton Fucsovics.

Wawrinka, the 2014 champion, bowed out after a 7-5 6-1 4-6 2-6 7-6 (11-9) loss to Fucsovics on a warm Wednesday in Melbourne.

Fucsovics saved three match points on John Cain Arena in an encounter that lasted three hours, 59 minutes.

Wawrinka led 6-1 and 8-4 in the super tie-break, but Fucsovics won the final five points and seven of the last eight.

The Hungarian continues to enjoy the year's first grand slam, where he has reached the fourth round twice in the past three years.

Wawrinka, though, has struggled in Australia in recent years.

The Swiss star has now been eliminated in the second round in three of the past four years, while reaching the quarter-finals in 2020.

Wawrinka rallied from two sets to love down and 5-3 behind in the fifth, but wasted his chances in the super tie-break.

Serena Williams is embracing the absence of line judges at this year's Australian Open as the record-chasing American superstar dubbed herself a "futurist, like Iron Man" after reaching the third round. 

The Australian Open is taking place without linespeople 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 line judges with technology as the tournament seeks to limit the number of people on court amid the COVID-19 pandemic.

After easing past Nina Stojanovic 6-3 6-0 on Wednesday, 23-time grand slam champion and seven-time Australian Open winner Williams welcomed the use of technology.

"I like it," Williams, who is looking to equal Margaret Court's record of 24 slams, told reporters when asked about the technology post-match. "I didn't like it in Cincinnati because they had that in Cincinnati and I was, it was different. It was weird. 

"I like it now because it takes away a lot of the human error, which clearly I definitely don't need. I should be the biggest fan of that. 

"But I feel like sometimes I definitely still want to see that ball, but I'm like, okay, even if I see it, the computer's going to show me what the computer just said. So that's kind of how I think about it. 

"I'm a futurist, like Iron Man, so I definitely love technology and it's something that I invest in and so, yeah, I really think is right up my alley."

Williams owns a 359-51 grand slam record in her illustrious career – the only other player to pass 300 victories in the Open Era is Martina Navratilova (306-49).

The 39-year-old Williams is bidding to win her 11th major crown since turning 30.

Only Court (three), Navratilova (three), Chris Evert (two), Billie Jean King (two), Ann Jones (one), Angelique Kerber (one), Li Na (one), Flavia Pennetta (one) and Virginia Wade (one) have won grand slam silverware in their 30s.
