Russell Westbrook has vowed to make amends after accepting the blame for the Los Angeles Lakers' surprise defeat to the Oklahoma City Thunder.

The Lakers, without LeBron James for a second game running due to an ankle injury, failed to protect a 26-point first-half lead as they fell 123-115 against a previously winless Thunder team.

Westbrook got his first triple-double for the Lakers in Wednesday's contest, but he also had 10 turnovers and was ejected late on for a second technical foul.

Nine-time NBA All-Star Westbrook took issue with Darius Bazley for scoring on a breakaway dunk, rather than dribble out the clock, with 1.5 seconds left in a feisty conclusion.

But while standing by his actions that led to that dismissal, the 32-year-old concedes that he could have done more to prevent his side from falling to a third defeat in five games.

"How I play the game, I'm more old-school," he said when asked about his confrontation with Bazley. "When s*** like that happens, I don't let it slide. 

"In the game of basketball, there's certain things you just don't do. Like in baseball, you don't flip the bat. 

"There's certain things you don't do in sports when the game's already over. And I didn't like it. Simple as that."

Westbrook, who ended the contest with 20 points, 14 rebounds and 13 assists, added: "I got to take care of the ball. There were too many mishaps allowed. 

"It's my fault. It's on me. But I'm going to take care of it. I know that. And keep the game simple. We need those possessions, especially in games like this."

Westbrook reached 7,000 career rebounds in the game, joining Oscar Robertson, Jason Kidd and James as the only players with at least 7,000 rebounds and 7,000 assists.

But it was not enough to prevent his side avoiding defeat as the Lakers allowed 115 points or more for the fifth game running this season – their longest ever such streak.

The Lakers may be going through a transitional phase with a number of new players on top of injuries to contend with, but Anthony Davis is not interested in excuses.

"This ain't no adjustment period at all," he said. "Not this game. That's just straight on us. 

"This isn't an adjustment game where I feel like it's, 'Oh, we're still learning each other'... Nah. Not this game."

The Lakers are ninth in the Western Conference ahead of their return to action on Friday against the Cleveland Cavaliers.

Jose Altuve admits equalling Bernie Williams for career postseason home runs means a lot but says it only matters as long as the Houston Astros are winning.

Altuve brought up his 22nd career postseason home run in the seventh inning to cap the Astros' 7-2 win over the Atlanta Braves in Game 2 to level the World Series on Wednesday.

The 31-year-old drew level with Williams in equal second on the overall majors list for postseason homers, behind only Manny Ramirez on 29.

“To hit 22 homers in the playoffs and tie [Williams] – always every time that my name is mentioned, before it was Derek Jeter, now it's Bernie Williams – it means a lot to me," Altuve told reporters.

"It makes me keep going out there, hitting homers to help my team, to keep accomplishing things like this. As long as we win, everything's good.”

Altuve scored the opening run of Game 2, with Alex Bregman driving him home in the first inning, finishing the game with two hits, two runs and one RBI. He had gone zero-for-five in Game 1.

The second baseman is hitting at .200 with four home runs, eight RBIs and 10 hits this postseason but team success is the main objective.

"For me, stats in the playoffs don’t matter, as long as you're winning," Altuve said.

"You could be zero-for-20 but if you get the big hit, that's what playoffs are about. I went zero-for-five last night but I didn’t care, I show up, I tried to get good pitches to hit.

"I'm glad I helped my team win tonight."

Five right-handed Astros hitters had six hits, five RBIs and one home run between them on Wednesday.

Houston have scored five or more runs in 10 games this postseason, which is tied for the second most in a single postseason, trailing only the 2015 Kansas City Royals with 11.

Kevin Durant has admitted the Brooklyn Nets are missing absent star Kyrie Irving following their third defeat in the new NBA season but is bullish they can turn around their stuttering form.

The Nets were beaten 106-93 by the Miami Heat on Wednesday, their third double-digit defeat leaving them with a 2-3 record.

Durant top scored for the Nets with 25 points along with 11 rebounds, while James Harden continues to work into the season, with 14 points.

Irving's absence, due to his vaccination status, has been a major talking point for the Nets and with limited contributions from guards Joe Harris (15 points and three reounds) and Patty Mills (four points, three rebounds and five assists) on Wednesday, Durant conceded he was being missed.

"I know what you want me to say," Durant told reporters after the game. "Yeah, we do miss Kyrie. We do. He's a part of our team.

"For the most part we've been generating great shots. We've been getting into the paint. It's a matter of knocking it down. I think it'll come."

Harden's form is another concern for the Nets as he re-discovers his touch after rehabbing from a hamstring injury.

The 2018 NBA MVP, who joined the Nets from the Houston Rockets in January, is averaging 16.6 points, 7.0 rebounds and 8.0 assists per game this season.

Harden has scored 15 or fewer points for the past three games, the first time that has happened since the 2011-12 season.

"I had no opportunities to play pickup or nothing this summer," Harden told reporters. "Everything was rehab for three months, from a Grade 2 injury that happened three times in one season.

"This is my fifth game of trying to just play with competition against somebody else and as much as I want to rush the process and be back to hooping and killing, [you need to] take your time."

Harden shot four-for-12 from the field and hit three-for-eight from beyond the arc against the Heat.

"[I'm] Just getting more confident, being aggressive," Harden said. "It's getting better every single game.

"As much as I want to get back to just [scoring] 30s and 40 points, I can't do that. As much as I want to, obviously I would love to."

The Brooklyn Nets' stuttering start to the season continued with their third defeat in five games as they went down 106-93 at home to the Miami Heat.

Jimmy Butler starred for the Heat with a double-double with 17 points and 14 rebounds as well as seven assists and four steals as Miami improved their record to 3-1.

Bam Adebayo stole the show in the final quarter as the Nets threatened to overtake them, landing three big dunks to finish with 24 points and nine rebounds.

James Harden had some bright moments but only managed 14 points with seven rebounds and seven assists, while Kevin Durant had 25 points and 11 rebounds.

All three Nets defeats this season have been by double-digit margins as they continue to miss Kyrie Irving who is absent due to his vaccination status.

Giannis hits 40 in Bucks defeat

Giannis Antetokounmpo scored 40 points but it was not enough as the Milwaukee Bucks suffered their second loss in their title defence 113-108 to the Minnesota Timberwolves.

Antetokounmpo had 40 along with 16 rebounds and seven assists, while all five Timberwolves starters contributed strongly led by D'Angelo Russell (29 points, five rebounds and six assists) and Anthony Edwards (25 points, seven rebounds and three assists).

Harrison Barnes (22 points, nine rebounds and four assists) drained a turnaround triple on the buzzer to clinch the Sacramento Kings a 110-107 win over last season's the Phoenix Suns who had closed a 13-point fourth-quarter deficit late in the game, led by Devin Booker (31 points, six rebounds and eight assists).

The Cleveland Cavaliers added another impressive scalp to their list this season as they downed the Los Angeles Clippers 92-79 with Collin Sexton scoring 26 points.

Westbrook turnovers as Lakers lose

Russell Westbrook got his first Los Angeles Lakers triple-double but he also had 10 turnovers in their 123-115 loss to the Oklahoma City Thunder, with LeBron James absent due to an ankle injury.

LaMelo Ball struggled with only seven points, shooting three-from-14 from the field and only one-from-five beyond the arc as the Charlotte Hornets won 120-111 over the Orlando Magic.

Khris Middleton's three-point radar was off in the Bucks loss to the Timberwolves, shooting one-from-eight and contributing only 16 points, leaving Antetokounmpo with too much to do.

The Houston Astros have levelled the World Series after a four-run second inning and another Jose Altuve postseason home run to win 7-2 over the Atlanta Braves in Game 2 on Wednesday.

The Braves had won Game 1 at Houston's Minute Maid Park 6-2 on Tuesday, but the Astros showed intent opening up a 5-1 lead after two innings.

Altuve's seventh-inning solo blast extended the lead to 7-2, taking him to 22 postseason homers, equalling Bernie Williams for second in majors history.

The Astros second baseman, who has four home runs this postseason, trails only Manny Ramirez for postseason homers with 29.

Astros starting pitcher Jose Urquidy played a strong role with seven strikeouts with two runs across five innings, outpitching Braves starter Max Fried who allowed seven hits and five earned runs.

Urquidy becomes the fourth Astros pitcher to have seven or more strikeouts and no walks in a World Series. Eddie Rosario, who came into the game with 20 hits this postseason, had an off-night with no hits.

Altuve scored the opening run from Alex Bregman's first-inning sacrifice fly, before Travis d'Arnaud's second-inning home run tied the game up.

Houston blew the game open at the bottom of the second inning, with Jose Siri's RBI single followed by Martin Maldonado's single allowing Yuli Gurriel and Siri to get home, the latter after an Eddie Rosario fielding error. Michael Brantley's base hit drove in Maldonado too.

The Astros had five hits in the second inning, which matched their most ever in an inning in a World Series game, having had five hits in the second inning in Game 3 in 2017.

Freddie Freeman's single got d'Arnaud in for his second run in the fifth inning, before Ozzie Albies mistake on second base allowed Yordan Alvarez to score in the sixth inning, before Altuve's homered to left field in the seventh inning.

Astros at Braves

Both sides will travel on Thursday as the series moves to Atlanta for Game 3 on Friday.

Jannik Sinner continued his push for an ATP Finals spot with a straight-sets defeat of Reilly Opelka in the first round of the Vienna Open, while Carlos Alcaraz exacted revenge on Andy Murray.

Sinner won his fourth title of what has been an outstanding season for the Italian in Antwerp last weekend and is only 110 points adrift of Hubert Hurkacz in the battle for the final place in the season-ending event in Turin.

Murray did the 20-year-old a favour by knocking Hurkacz out of the ATP 500 tournament in the Austrian capital on Monday and seventh seed Sinner eased to a 6-4 6-2 win over American Opelka two days later.

Sinner, who will overtake Pole Hurkacz if he reaches the semi-finals this week, won 93 per cent of points behind his first serve and did not face a break point in a resounding win and will play Dennis Novak in the second round.

Murray beat Alcaraz at Indian Wells this month, but the 18-year-old rising star from Spain turned the tables on the three-time grand slam champion with a 6-3 6-4 second-round win in Vienna.

Former world number one Murray struggled with his serve and was broken five times as he made an early exit.

Third seed Matteo Berrettini beat Nikoloz Basilashvili 6-7 (5-7) 6-2 6-3 to reach the third round, while Diego Schwartzman, Gael Monfils and Lorenzo Sonego moved into the second round.

In the St Petersburg Open, defending champion Andrey Rublev beat Ilya Ivashka 6-4 6-4 to reach the quarter-finals along with Denis Shapovalov, a 2-6 6-3 6-0 winner against Pablo Andujar.

Jan-Lennard Struff also moved into the last eight, with Karen Khachanov and Marin Cilic securing first-round wins.

Simona Halep eased to victory over compatriot Elena-Gabriela Ruse on home soil in Romania to advance through to the last 16 of the Transylvania Open.

Ruse won her first WTA title at the Hamburg European Open in July and reached the final of the Palermo Ladies Open later that month, but she was second best against Halep.

The top seed produced a commanding performance as she held serve throughout and broke her opponent twice in both sets to progress 6-1 6-2 in a time of 73 minutes.

Halep, who departed at the quarter-final stage of the Kremlin Cup last week, is on course to meet US Open winner Emma Raducanu in the semi-finals in Cluj.

Anett Kontaveit also prevailed on Wednesday with a straight-sets win of her own, the second seed seeing off Aleksandra Krunic 6-3 7-5.

The 25-year-old, seeking her third WTA 500 indoor trophy in the space of two months, made the most of some Krunic errors to set up a last-16 tie with Alison Van Uytvanck.

Anhelina Kalinina earlier beat Anna-Lena Friedsam 6-2 6-2 to become the first player to book their place in the quarter-finals.

At the Courmayeur Open in Italy, top seed Dayana Yastremska required three sets to overcome Kateryna Kozlova 6-1 3-6 7-5.

Clara Tauson and Ann Li also avoided upsets as they beat Giulia Gatto-Monticone and Kamilla Rakhimova respectively.

Alejandro Valverde has confirmed he will retire at the end of the 2022 season and hopes to contest at least one more grand tour on home soil in the Vuelta a Espana.

Next year will be the veteran rider's 21st campaign in professional cycling and he sees no need to continue further despite still feeling able to compete.

Valverde, who ruled out competing at next year's Tour de France, will remain in a coaching role with the Movistar team after his retirement, given his contract will still have two years to run.

The 41-year-old won the Vuelta in 2009 and has achieved a further six podium finishes at the prestigious event.

Valverde has also finished third in the Tour de France and come third in the Giro d'Italia in the only time he competed in the Italian stage race in 2016, as well as being crowned world road champion in 2018.

The Spaniard returned from a two-year suspension due to the Operacion Puerto investigation in 2012, having had all of his 2010 results annulled after a lengthy legal battle.

"I say with total conviction, 100 per cent, that 2022 is going to be my last year," Valverde told Sports Radiogaceta.

"Even though my level is good at 42, it makes no sense to extend longer after 21 years in the business. What more do I want? My time has come.

"I want to enjoy my last season as a pro. I don't have my season sketched out yet, but a start at the Tour de France is already excluded.

"I hope to race the Vuelta next year, and we will study the Giro route too, and then there is the Classics and all the races on the Spanish calendar.

"When I retire I have a contract for two more years in the Movistar team. I will try to help the team as much as I can, especially by coaching young riders, which is something I like a lot."

Novak Djokovic's participation at the Australian Open has been cast in doubt once again as Victorian premier Daniel Andrews indicated the state that hosts the event will not welcome those who are not fully vaccinated against COVID-19.

Australian minister for immigration Alex Hawke revealed last week Djokovic, who has won a record nine titles at Melbourne Park, could only take part in January's tournament if he has received both jabs.

But the 20-time grand slam winner, who has declined to reveal his vaccination status, was given hope of competing after prime minister Scott Morrison said there would be exemptions should the state of Victoria – which includes Melbourne – agree.

However, responding to those comments on Wednesday, Andrews made clear his government would not apply for any sort of dispensation as it would not be fair on the other players and spectators who are fully vaccinated.

"The federal government manages the border and to the extent that anything the federal government says on this is clear, because their position has gone 180 from what the immigration minister said," Andrews said.

"What I'm making equally clear on behalf of every vaccinated Victorian who is doing the right thing... the only fair thing to do is to be very clear with every Victorian, my government will not be applying for an exemption for any unvaccinated player."

Recent reports suggested that over a third of professional players on the ATP Tour remain unvaccinated ahead of the 2022 Australian Open, which runs for two weeks from January 17.

Andrews added: "I'm not going to ask and actually require people sitting in the grandstand, people working at the event, to be vaccinated while players aren't.

"So we're not going to be applying for an exemption, so the issue is basically resolved."

Andrews also stated the same approach will be taken when Formula One returns to Melbourne in April next year.

Speaking last week, world number one Djokovic – who beat Daniil Medvedev earlier this year to win his latest Australian Open crown – told Serbian newspaper Blic: "Things being as they are, I still don't know if I will go to Melbourne.

"I will not reveal my status whether I have been vaccinated or not, it is a private matter and an inappropriate inquiry.

"Of course I want to go, Australia is my most successful grand slam tournament. I want to compete, I love this sport and I am still motivated.

"I am following the situation regarding the Australian Open... I believe there will be a lot of restrictions just like this year, but I doubt there will be too many changes."

Atlanta Braves star Jorge Soler conceded Charlie Morton's injury had taken the shine off his team's 6-2 triumph over the Houston Astros in Game 1 of the World Series.

Morton took a hard grounder off the leg in the second inning but remained in the game to finish out the frame, then struck out the first batter of the third before leaving when the pain became too intense.

X-rays revealed the 37-year-old had suffered a broken right fibula, ruling him out of the remainder of the series.

Soler, who hit the third pitch of the game for a home run, said of Morton's setback: "It was extremely challenging for us.

"We saw him getting treatment and getting worked on. He went back out there to pitch on that broken leg.

"It was really challenging and emotional for us to have to see him in the game being hurt, our World Series opener, starter."

In the 117th edition of the World Series, Soler became the first player to lead off the top of the first inning of Game 1 with a homer – a welcome development for Atlanta as teams that score first in the 2021 postseason are now 25-7. 

"The energy was amazing and electric, especially after we took a 1-0 lead after that home run," said Soler.

"I feel extremely grateful to be here and be a member of this organisation. I feel like Atlanta opened its arms for me. They traded for me, and they gave me opportunity to play every day.

"So as far as I'm concerned, I'm extremely grateful to the organisation, to the fans who have definitely supported us, and like I said, I'm very happy to be here."

Astros starter Framber Valdez had been dominant early in games, allowing only one run in the first two innings over his previous six games combined, but he would retire only six of the 15 men he faced Tuesday before departing down 5-0 with no outs in the third inning. 

Beyond Soler's leadoff blast, the other big offensive blow for the Braves was a two-run laser over the left-field fence by Adam Duvall in the third that drove Valdez from the game.  

Game 2 is on Wednesday in Houston with Max Fried taking the mound for the Braves against the Astros' Jose Urquidy. 

Reigning MVP Nikola Jokic missed the second half of the Denver Nuggets' 122-110 loss to the Utah Jazz on Tuesday with a knee injury but the team does not believe it will be a serious problem. 

Jokic was off to a torrid start when he banged knees with Jazz big man Rudy Gobert with about two minutes to play in the first half and left the game. 

Denver head coach Michael Malone said he decided to keep Jokic on the bench after a brief half-time discussion with the 26-year-old. 

The official diagnosis was a knee contusion and Malone said he was not sure if Jokic would need further testing. 

"I don't think it's anything too serious," Malone told reporters. "I went up to Nikola as he was warming up at half-time and said how do you feel and he said 'It feels a little weak' and I just shut him down.

"Nikola's a tough kid, we've seen him time and time again play through injuries, never sit out. Second night of a back-to-back, he's far too important for this team for us to risk him being out there if he's not feeling confident about it."

Though he played only 15 minutes Tuesday, Jokic ended up leading the Nuggets with 24 points and six assists, and he also added six rebounds before departing. 

Jokic made eight of nine shots from the field including all three of his three-point tries. 

After suffering 12-point losses to the Jazz and Cleveland Cavaliers on successive nights, the Nuggets (2-2) are off until hosting the Dallas Mavericks on Friday. 

Playing without the injured LeBron James, the Los Angeles Lakers saw their other two superstars step up in a 125-121 overtime defeat of the San Antonio Spurs. 

Anthony Davis had 35 points and 17 rebounds and Russell Westbrook contributed 33 points, 10 rebounds and eight assists to carry the Lakers on the road. 

James injured his right ankle Sunday against the Memphis Grizzlies but remained in the game. Though he entered the day listed as "probable" against the Spurs, coach Frank Vogel ruled him out before the game. 

Malik Monk got the start in James' place and finished with 17 points but the Lakers needed their big names to pull this one out. 

Los Angeles trailed by 12 in the fourth quarter before rallying to take the lead, but that momentum was halted when Davis went down late in the period with an apparent leg injury. 

Westbrook took control in overtime, though, and the Lakers will have to hope for good news on the injury front. 

Vogel said after the game that Davis banged knees with another player and his status for Wednesday's game at the Oklahoma City Thunder is unclear. 

Curry, Warriors rally to stay perfect 

The Golden State Warriors staged a second-half comeback to defeat Oklahoma City 106-98 and remain unbeaten while their opponents continue to search for their first victory of the season. The Thunder (0-4) led 74-64 with 4:15 remaining in the third quarter before Golden State (4-0) went on a 21-2 run to take control. Stephen Curry scored 23 points to lead the Warriors, while Andrew Wiggins had 21 and Damion Lee chipped in 20 off the bench. Shai Gilgeous-Alexander had 30 for Oklahoma City, who shot just 41.9 per cent from the field (36 of 86).

The Utah Jazz improved to 3-0 with a 122-110 home win over the Denver Nuggets, who lost reigning NBA MVP Nikola Jokic to a knee contusion late in the first half. Jokic led the Nuggets with 24 points despite playing only 15 minutes, while Rudy Gobert had 23 points and 16 rebounds for Utah. 

Luka Doncic had 26 points, 14 rebounds and seven assists to lead the Dallas Mavericks past the Houston Rockets 116-106. 

Curry disappears as Sixers fall to Knicks

Two days after scoring 28 points in a Philadelphia victory, Seth Curry was held to just four as the 76ers fell 112-99 to the New York Knicks. Curry missed all four of his three-point attempts and attempted only six shots overall in 30 minutes. Joel Embiid also struggled, making only two of seven shots from the field on a 14-point night.
