Australia's Travis Head struck a century to punish England on a rain-affected opening day of the fifth and final Ashes Test at the Bellerive Oval in Hobart.

The hosts, who have an unassailable 3-0 lead, finished Friday on 241-6 having earlier been reduced to 12-3 by an England side who won the toss and chose to bowl first.

England showed five changes from last week's drawn fourth Test in Sydney, including a debut for Sam Billings, and started in an impressive manner.

David Warner (0), Usman Khawaja (6) and Steve Smith (0) all went by the start of the 10th over, while Marnus Labuschagne would have followed had Zak Crawley not fumbled.

That may well prove a decisive moment in the final Test as Labuschagne and Head launched a counter-attack by scoring 53 runs from the next seven overs.

But on 71 from 72 balls, Labuschagne comically wrong-footed himself when attacking a Stuart Broad delivery and could only watch from the floor as Australia lost another wicket.

England lost bowler Ollie Robinson to injury and their problems were compounded by the work of Head, who continued to rack up the runs when joined by Cameron Green.

Head survived a big scare on his way to reaching 101 from 113 balls, but his day was ended after he chipped a Chris Woakes delivery to Robinson at mid-on.

Green got to 74 before holing out at deep mid-wicket and only nine more balls were bowled due to rain, with Mitch Starc (0) and Alex Carey (10) to resume play on Saturday.

Travis keeps his Head after Crawley loses his

England could not have asked for a much better start on the green surface, with Robinson and Broad dismantling Australia's top order by dismissing Warner and Smith for ducks.

But Crawley's drop of Labuschagne, combined with England's wayward bowling from that point on, allowed Head – recently sidelined due to COVID-19 isolation – to grab the fifth Test by the scruff of the neck.

He went past the 100 mark, becoming the seventh Australian to do so in a day/night men's Test innings after Warner, Labuschagne, Khawaja, Smith, Shaun Marsh and Peter Handscomb.

Green shoots of recovery

Australia all-rounder Green had a maiden hundred in his sights, only to fall to Mark Wood's short-ball trap 16 runs shot of three figures.

At 22 years and 225 days, he is the youngest player to score 50 or more runs in a men's Test innings for Australia at Bellerive Oval and the fourth youngest overall at the ground.

Philosophical differences were behind the Houston Texans' decision to part with head coach David Culley after one season with the team, according to general manager Nick Caserio.

The Texans ended a disappointing campaign 4-13, and offensive coordinator Tim Kelly has also departed after eight years with the franchise, which finished third in the AFC South for a second consecutive season.

The Texans ended their season with a 28-25 loss to the Tennessee Titans, leading a late fightback against their rivals after finding themselves 21-0 down at the halfway point.

Caserio, who has been in the GM post for just a year, released a statement explaining the decision to relieve both Culley and Kelly of their duties, with the Texans ending the season ranked last in the NFL for total offense, and Culley having reportedly resisted attempts to make changes to his offensive staff. 

"Earlier today, I met with David Culley and Tim Kelly to inform them we will be moving in a different direction with the head coach and offensive coordinator positions," the statement read. "I came to this difficult but necessary decision after reviewing our football operations.

"While a change after one season is unusual, we had philosophical differences over the long-term direction and vision for our program moving forward. 

"We appreciate coach Culley for helping us navigate through a difficult season, but it is my responsibility to make decisions that I feel are best for our organisation.

"The search for the next coach of the Houston Texans will begin immediately."

Barbora Krejcikova saved seven match points on her way to beating Anett Kontaveit in a thrilling Sydney Tennis Classic semi-final on Friday.

The world number four prevailed 0-6 6-4 7-6 (14-12) in a match that went the distance and will take on Paula Badosa, who beat in-form Daria Kasatkina in the other semi-final.

Krejcikova had lost five in a row against top-10 players and was soundly beaten in the first set, but she held in the second and earned the only break in the ninth game to level up. 

That set up an incredible decider, which fourth seed Kontaveit led 6-5, but she could not take the first three of her match points as Krejcikova battled valiantly to force a tie-break.

Krejcikova felt her opponent's pain as she then squandered two match points of her own when leading 6-4. 

It appeared neither player wanted to win as two more match points went begging for Krejcikova and four for Kontaveit in what turned into a real classic.

But Krejcikova eventually took her fifth opportunity to see off Kontaveit and reach a sixth WTA singles final.

"I think from both sides it was a really, really tough match," Krejcikova said. "I think we played wonderful tennis. 

"It was very, very tight, and I'm really happy that I was able to hold the nerves better and that I won this match.

"I was just playing, just trying to fight for every single ball. When I had those match points down, I was just trying to figure out how to build up the point and how to win the point."

Badosa awaits Krejcikova in Saturday's final after beating Kasatkina in a match with far fewer twists and turns.

Competing in her second semi-final in as many weeks, it was similar disappointment for Kasatkina as she fell to a 6-2 6-2 loss.

French Open quarter-finalist Badosa hit 26 winners to Kasatkina's 12 and did not look back after winning 14 of the opening 16 points.

At the Adelaide International 2, meanwhile, it will be an all-American final as Madison Keys and Alison Riske advanced past Tamara Zidansek and Coco Gauff respectively.

Riske was given a walkover win against Zidansek, who withdrew with an abdominal injury, while Keys beat compatriot Gauff in three sets.

Real Madrid defender Dani Carvajal will miss the Supercopa de Espana final against Athletic Bilbao in Riyadh on Sunday after testing positive for coronavirus.

Carvajal started the 3-2 semi-final win over fierce rivals Barcelona at King Fahd Stadium, but will not feature in the showpiece at the same venue this weekend.

The LaLiga leaders revealed on Friday that the Spain international had returned a positive COVID-19 test.

Lucas Vazquez replaced Carvajal at the end of normal time in the victory over Barca, which was secured courtesy of Federico Valverde's extra-time strike.

Holders Athletic came from behind to beat Atletico Madrid 2-1 in the second semi-final on Thursday.

Steve Kerr insisted the Golden State Warriors' defeat to the Milwaukee Bucks is not a cause for concern as it is normal for sides to go through difficult spells.

The Warriors were beaten 118-99 by a Giannis Antetokounmpo-inspired Bucks on Thursday to make it four defeats in their past five games.

Despite losing to the Dallas Mavericks, the New Orleans Pelicans, the Memphis Grizzlies and the Bucks, Kerr's side are second in the Western Conference with a 30-11 record.

Without the injured Draymond Green once again, the Warriors showed some fight in the second half to reduce a 39-point deficit to 18, but that was as close as they got to the Bucks.

"I know we just got our butts kicked, but we're just in a rough patch in our season," Kerr said at his media conference. 

"It happens to every team, every year pretty much with very few exceptions. 

"We're in a little bit of a rut and we were playing a team that was ready and played a great first half. We're a little out of sorts. We've just got to get back on track, and we will."

Andy Murray powered through to his first ATP Tour final since October 2019 after a stellar win over Reilly Opelka at the Sydney Classic.

Murray won 6-7 (6-8) 6-4 6-4 against his American opponent, with fourth seed and world number 25 Opelka undone by the British wildcard.

Three years have passed since Murray came to Australia and indicated he was close to retirement due to hip trouble.

There have been highs and lows since then as the three-time grand slam winner has fought to resuscitate his career. His lone ATP final appearance since that point came at the 2019 European Open in Antwerp, where he beat Stan Wawrinka to land a surprise title.

Now he is back in another title match, for what will be just his fourth final on the main tour since the end of the 2016 season, when he reached world number one status.

Opelka is renowned as a big server and duly sent down 20 aces and four double faults, but Murray showed he can compete on that front too with 16 aces and no doubles.

The Scot also won an impressive 88 per cent of points when he landed his first ball in court, and his serve was not broken at any point.

Murray was awaiting the winner of the second semi-final between his fellow Briton Dan Evans and Russian Aslan Karatsev.

Five-time Australian Open runner-up Murray has been drawn to face Georgian Nikoloz Basilashvili in the first round of the grand slam at Melbourne Park next week. He beat 23rd-ranked Basilashvili in round two in Sydney.

Manchester City and Chelsea were both in the market for a striker ahead of the 2021-22 season.

Although Chelsea sealed Romelu Lukaku's return – for a club-record fee reported to be £97.5million – City were unable to break Tottenham's resolve and sign Harry Kane.

For a brief time towards the end of August, it seemed Cristiano Ronaldo would be heading to the Etihad Stadium. Yet City again came away empty-handed – Ronaldo, like Lukaku, returning to a former club as he joined rivals Manchester United.

Indeed, City were once linked with Lukaku, with the forward himself claiming he had turned down an approach in 2020. But Pep Guardiola's team have, so far, cast aside any doubts that a lack of an out-and-out striker would cost them dearly.

City looked set to be in a three-way title race earlier in the season, alongside Chelsea and Liverpool. Heading into their second top-flight match of 2022, they are 10 points clear of the Blues and 11 clear of the Reds.

City turned in a statement performance in a 1-0 win at Stamford Bridge in September and, while rumours swirl of impending approaches for Erling Haaland or Dusan Vlahovic, two of Europe's brightest striking prospects, it will be Guardiola's 4-3-3, false nine system that Thomas Tuchel must look to counter on Saturday.

Using Opta data, Stats Perform assesses how the respective attacks have stacked up this season.

Rom's return

It would be fair to say Lukaku's return to Stamford Bridge has not yet matched what was expected. Having led Inter to their first Serie A title in 11 years, Lukaku re-signed for Chelsea to much fanfare and, undoubtedly, as one of the most fearsome finishers in European football.

Lukaku's second Chelsea debut could hardly have gone better as he opened the scoring against Arsenal after just 15 minutes, putting his strength, pace and positioning prowess on full display.

Yet he has so far failed to hit his stride. His five league goals from 13 appearances ranks him behind Mason Mount and Jorginho (both six) in Chelsea's squad, albeit the latter has netted all of his from the penalty spot.

Lukaku's goal return has come from a total of 22 shots, the fifth-most in Chelsea's squad, at an average of 2.3 per 90 minutes played. However, his rate of scoring every 166 minutes in the league puts him top of Chelsea's squad in that metric.

But that has been another issue with his comeback. Lukaku has featured for just 828 minutes in the league, starting only eight times, with 12 team-mates accumulating more game time.

An injury sustained in a Champions League win over Malmo in October kept him out of action for several weeks and he subsequently contracted COVID-19.

Then, late in December after he scored in successive matches against Aston Villa and Brighton and Hove Albion, Sky Italia released an interview, conducted several weeks previously, in which Lukaku questioned Tuchel's tactics and suggested he could leave Chelsea.

Tuchel reacted strongly, dropping the forward for a pivotal clash with Liverpool on January 2, which finished 2-2. Lukaku apologised and returned to Chelsea's side for the first leg of their EFL Cup semi-final against Tottenham.

One of Lukaku's complaints was about how Tuchel has used him so far. 

Last season, playing typically in a 3-5-2 system at Inter, Lukaku averaged three shots, 1.5 attempts on target, 7.3 touches in the opposition box and 1.6 chances created per 90 minutes, across 36 Serie A appearances. But those figures have so far dropped to 2.4 shots, 0.9 attempts on target, 6.4 touches in the opponent's box and 1.5 chances created this term, with the forward deployed as a target man to combine with Mason Mount, Kai Havertz, Christian Pulisic and the rest of Chelsea's attack.

It is a role that does not seem to suit Lukaku best, though Tuchel has made it clear who the boss is.

False nines and a flying full-back

Chelsea and City have played 21 league games this season, but Guardiola's team have netted six goals more. They average one every 36 minutes, compared to Chelsea's 43, and have out-shot the Blues 391 to 320.

This is all without a recognised number nine but, as proved by their charge to a third league title in four seasons in 2020-21, City have cracked the code of having any player but a centre-forward lead their line.

Whether it is Phil Foden, Kevin De Bruyne, Raheem Sterling, Jack Grealish, Ilkay Gundogan, the magnificent Bernardo Silva or, occasionally, the man who wears nine, Gabriel Jesus, City have a wealth of stellar options to slot into that role.

Sterling and Silva, who has been in sensational form all season, lead the way with seven goals each. It is a testament to Guardiola's man management that the duo, who might have left the club in 2021, are in such rich form.

Riyad Mahrez – the only City attacker with a consistent position – has netted six. De Bruyne and Foden have added five apiece.

City share their goals around for fun, while three players (Sterling, Silva and Jesus) have had over 100 touches in the opposition box, with Grealish on 99. No Chelsea player has managed more than 76 (Mount). 

De Bruyne's 36 chances created is more than any other player in City or Chelsea's squads, while the Belgian is level with Foden and Gundogan for big chances created (six), with Mount the only Blues player able to match them.

Allowing whichever front five plays for City to flourish is Rodri, who has taken the mantle from Fernandinho at the base of midfield, and creative support comes from the superb Joao Cancelo.

He has provided four league assists from 22 chances created, which ranks him sixth in the competition for defenders, with his four big chances tied for fourth, behind Trent Alexander-Arnold (11), Andrew Robertson and Reece James (five), who is a big injury miss for Chelsea.

It is not just Cancelo's passing and crossing that supports City's attack, however, with the full-back registering fourth in the league, behind three club-mates, for total carries (380) and sixth for carry distance (3,867 metres). Thiago Silva is the sole Chelsea player to have a place in the top 10 for either statistic.

Finely balanced

While City seemingly have the edge heading into Saturday's contest, Tuchel found a way to thwart Guardiola's system last season.

City countered this with their aggressive approach at Stamford Bridge but only four months previously, Guardiola's men fell short in their first Champions League final – Havertz scoring the winner in a match that perhaps forced City to make their move for Kane.

Tuchel won all three of his encounters with City in 2020-21, though those matches are the only times he has beaten Guardiola, who won three of their five Bundesliga meetings.

Chelsea went toe-to-toe with Liverpool and came out with a point earlier this month, though if Chelsea are to rope City back in, they need their investment in Lukaku to pay off.

Should City's death by a thousand cuts prevail, Chelsea's title challenge might well and truly have bitten the dust.

Giannis Antetokounmpo dropped his third triple-double of the season to lead the Milwaukee Bucks to a commanding 118-99 win over the Golden State Warriors on Thursday.

The two-time NBA MVP had 30 points, 12 rebounds and 11 assists in front of coach Mike Budenholzer, who was back after returning from the league's health and safety protocol.

Antetokounmpo's 28th career triple-double came in under 30 minutes played, making him the first player in NBA history to achieve that feat multiple times.

Kris Middleton added 23 points for the Bucks, who move to 27-17 for the season, while Bobby Portis and Grayson Allen registered 20 and 15 respectively.

The Warriors trailed 77-38 at half-time and have now lost four times in five matches, yet they still boast the second-best record in the Western Conference.

Grizzlies' run goes on

The Memphis Grizzlies finished strongly to overcome the Minnesota Timberwolves 116-108 and extend their franchise-record run to 11 wins in a row.

Desmond Bane scored 21 points and Jaren Jackson Jr. added 20 for the in-form Grizzlies, who were also inspired by John Konchar's 15 and career-best 17 rebounds.

The Grizzlies suffered their heaviest loss of the season when the sides met in November, but they pulled away late on in this back-and-forth encounter to go 30-14 in the West.

As for the Timberwolves, they have now let successive games slip away after also going down 128-125 against the New Orleans Pelicans with 1.3 seconds to go on Tuesday.

Nets beaten in Durant and Irving's absence

The travel-weary Brooklyn Nets were made to pay for resting NBA scoring leader Kevin Durant as they suffered a 130-109 defeat to the Oklahoma City Thunder.

Durant, James Harden and Kyrie Irving combined to great effect in the previous night's win at Eastern Conference-leading Chicago Bulls, but that trident was split up.

With Irving still unable to play home games due to vaccine laws in New York and Durant and Patty Mills watching on from the side, the Thunder ran out deserved winners.

Shai Gilgeous-Alexander led the way with 33 points, 10 rebounds and nine assists as the Thunder snapped a five-game losing run.

Elsewhere, Nikola Jokic powered the Denver Nuggets to a 140-108 win over the Portland Trail Blazers and the Pelicans were too strong for Los Angeles Clippers in a 113-89 win.

Jim Furyk rolled back the years with a hole-in-one at the Sony Open to finish the opening round in Hawaii one shot behind leader and defending champion Kevin Na.

The 51-year-old, who has 17 PGA Tour victories to his name, sunk the perfect shot on the par-three 17th on his way to finishing eight under on Thursday.

Furyk was hampered by a slow start at Wai'alae Country Club with a bogey on the opening hole, though that proved to be the American's only dropped shot in a round of 62.

That makes Furyk the oldest player to shoot 62 or better on the PGA Tour since 1983 as he looks to win the tournament for a second time, 26 years on from his previous triumph.

"I'm trying to get ready for this year. I want to be competitive this week," said Furyk, who made the sixth hole-in-one of his career and first since 2011.

"I want to compete and put myself in position, in the hunt, and also want to get a feel for where my game is and what I want to work on for the year."

Furyk will resume day two level with compatriot Russell Henley and a stroke behind blemish-free Na, who is aiming to defend the crown he won last year.

Na was on course for a sub-60 round, but three good birdie chances passed him by and he now has seven challengers within two shots of his lead.

The South Korean settled for 61 to tie his career-low round on the PGA Tour. He leads the way for the most rounds-of-62 or better since such data was first recorded in 1983 (10).

Na, Furyk and Henley are three of six past Sony Open winners in the top 10 after day one, along with Matt Kuchar, Patton Kizzire (both six under) and Ryan Palmer (seven under).

Elsewhere, Cameron Smith could not build on his record-breaking win at last week's Sentry Tournament of Champions as a couple of bogeys left him three-under par in a tie for 40th.

Diego Simeone believes Atletico Madrid will be held back from achieving their aspirations this season if they cannot address their problems in defending against aerial threats.

Atleti let a lead slip to lose 2-1 to Athletic Bilbao in the semi-final of the Supercopa de Espana in Saudi Arabia on Thursday.

The LaLiga champions looked set to face city rivals Real Madrid in the final at King Fahd Stadium on Sunday after Unai Simon's unfortunate own goal put them in front just after the hour mark.

Yet the holders mounted a great fightback in Riyadh on Thursday, Yeray Alvarez rising to head in a corner from Iker Muniain after 77 minutes.

Teenage substitute Nico Williams won it for Athletic nine minutes from time, finishing clinically with his left foot from inside the penalty area after Simeone's side failed to deal with another corner.

Jose Gimenez's red card for a dangerous challenge on Inigo Martinez added insult to injury for Atleti.

There were elements to the performance that pleased Simeone, but he fired a warning that his side are unlikely to challenge for trophies unless they can solve their issues in the air.

"There are things that can't be hidden. The team doesn't have defensive strength in aerial play and that takes away from us the possibility of having better games and better opportunities to be higher up in LaLiga and to stay in this competition," said the Atleti coach.

"This isn't the time to talk much. Everything looks much worse with the result, but there were good things. Joao [Felix] played a good game, [Angel] Correa worked, [Rodrigo] De Paul did well when he came on, [Mario] Hermoso's game was very good, Marcos [Llorente] was able to play for 45 minutes coming in with an overload in his glute, and we have to improve in training, on a day-to-day basis and get what comes to us from that."

Asked if it seemed his team had finally reached a point where they had stopped believing, he replied: "It's an opinion more than a question. I hear that as an opinion.

"We believe in the work we do. We're trying to improve. Since the Rayo [Vallecano] match [a 2-0 win on January 2], I think we've played good games, but we need to improve something very obvious that makes us lose points, [league] positions and stops us being in finals. It is up to us to improve that and increase the aggressiveness in the areas."

Llorente started the game at right wing-back before being replaced by Renan Lodi at half-time, but the pair between them only provided one cross from open play throughout the contest.

It laid bare the concerns Simeone has over that position following the sale of Kieran Trippier to Newcastle United.

While he is happy with the options at his disposal, with Sime Vrsaljko another who can play the role, Simeone said the club were exploring options in the transfer market.

"We have Vrsaljko as a replacement. He can play there. The club is working with what can be done in pursuit of the benefit of the club and of the team," he said.
