LeBron James was Tyrese Hailburton's favourite player growing up, and Los Angeles Lakers coach Darvin Ham knows his team must keep the Indiana Pacers star under lock and key.

The Lakers face the Pacers in the final of the inaugural in-season tournament in Las Vegas on Saturday.

Indiana overcame the Milwaukee Bucks to progress to the showpiece game, with 23-year-old point guard Hailburton finishing with 27 points and 15 assists.

Hailburton has impressed all season, averaging 26.9 points per game, and now gets a chance to face off against one of his childhood heroes in the form of Lakers star James, who was in fine form against the New Orleans Pelicans on Thursday.

"Like any kid born in 2000, LeBron was my favourite player growing up," Haliburton said. "And it's hard for him not to be for a lot of us.

"Growing up, I was a Cavs fan, then a Heat fan, then a Cavs fan again, then a Lakers fan before I got drafted. It's just how it went.

"To be able to compete against him in a championship is kind of like a storybook [ending] a little bit, and it's going to be a lot of fun.

"But that's the great part about being in the NBA, getting to compete against your idols on a nightly basis. I really look forward to that."

James might be Hailburton's idol, but Lakers coach Ham knows his team must find a way to keep the Pacers' talisman down.

"He's sneaky athletic. He has length to him, and his vision is incredible," Ham said. 

"I mean, the things he's able to do with the basketball, the way he sets up his teammates, looks off defenders, the way he pushes the pace in transition, he's constantly in attack mode.

"I think they've got a jewel, man."

Hailburton made his first All-Star appearance last season, though the Pacers have missed out on the playoffs in the last four campaigns.

"LeBron James is in his prime still," Pacers coach Ricky Carlisle noted.

"I'm watching the guy last night, and it's phenomenal. He's the only player in NBA history who has been the youngest player in the league and the oldest player in the league, both. That speaks to obviously an amazing run of longevity and, in his case, greatness.

"He's the all-time leading scorer, and if there's a Mount Rushmore, he's one of the guys on the NBA Mount Rushmore.

"That's what we're up against tomorrow. We're up against him and Anthony Davis and a lot of other very good players that are on a real uptick right now competitively.

"We've got our hands full. But if you're the Indiana Pacers and you're in the process of making the climb and you want great experience, this is the kind of challenge that you've got to love."

Ham added: "We've just got to be ready for a little bit of everything, but we can't get so caught up in trying to stop and prevent them from doing what they like to do. 

"We will, but we also can't forget to enforce our will upon the game, too. They have to guard us, too."

Derrick White scored 30 points and Kristaps Porzingis had 21 in his return to the lineup as the Boston Celtics remained perfect at home with Friday's 133-123 win over the New York Knicks.

Jayson Tatum chipped in 25 points to help Boston improve to 10-0 at TD Garden this season and bounce back from Monday's 122-112 loss to the Indiana Pacers in the NBA's In-Season Tournament quarter-finals.

Porzingis, who had missed the Celtics' previous four games with a strained left calf, tallied 19 points on 7-of-8 shooting in the first half to help stake Boston to a 74-65 lead at intermission.

The Celtics stretched their advantage to as many as 20 points in the third quarter and the Knicks never got closer than seven points down in the fourth.

Jalen Brunson and RJ Barrett each had 23 points for New York, which had won three straight prior to Tuesday's loss to the Milwaukee Bucks in the Tournament quarterfinals.

Fox leads rally as Kings top short-handed Suns

De'Aaron Fox scored 23 of his game-high 34 points in the fourth quarter as the Sacramento Kings dominated the second half en route to a 114-106 win over the Phoenix Suns.

Domantas Sabonis compiled 15 points, 17 rebounds and five assists for Sacramento, which overcame a nine-point half-time deficit by outscoring the Suns by a 33-12 margin in the third quarter.

Phoenix, which played without Kevin Durant due to an ankle injury and remains without fellow star Bradley Beal, shot 52.4 per cent in the first half to build a 59-50 lead. 

The Suns went 6 of 23 from the field in the third quarter, though, as the Kings fought back to tie the game before finishing the period on a 16-4 run to take an 83-71 advantage into the fourth.

Fox then took over in the final quarter as Sacramento gradually pulled away, with his 3-pointer with 1:44 remaining giving the Kings a comfortable 112-98 lead.

The slumping Suns lost for the fourth time in five games despite Devin Booker's 28 points on 10-of-14 shooting along with seven assists. Eric Gordon added 19 points for Phoenix.

Thunder continue mastery of Warriors with overtime win

Shai Gilgeous-Alexander had 38 points, Jalen Williams added 28 and the Oklahoma City Thunder rallied late in regulation before handing the Golden State Warriors a 138-136 overtime loss.

Chet Holmgren chipped in 21 points, including three free throws with 7.7 seconds left in the fourth quarter that forced overtime, as the upstart Thunder defeated the veteran Warriors for the third time in four meetings this season. 

Golden State fell to 10-12 on the season despite 34 points from Stephen Curry and 22 from Klay Thompson. Jonathan Kuminga posted 24 points and 12 rebounds off the bench before fouling out in OT.

The Thunder battled back from a 14-point second-quarter deficit, then never trailed in overtime after opening the session on a 12-3 run capped by a Holmgren 3-pointer that gave them a 130-121 lead with 2:40 left.

Golden State fought back and pulled to within 136-134 on Curry's 3-pointer with 29.7 seconds remaining, but Holmgren fed Luguentz Dort for a critical layup on the ensuing possession and the Warriors eventually ran out of time.

LeBron James quipped he was not too old to put his body on the line for the $500,000 per player cash prize that goes to the NBA's in-season tournament winners.

James' comment came after he played a starring role in the Los Angeles Lakers' 133-89 demolition of the New Orleans Pelicans in Thursday's semi-final.

Just over three weeks away from his 39th birthday, James finished with 30 points, eight assists and five rebounds at the T-Mobile Arena in Las Vegas.

He also got in the way of a Zion Williamson charge in the first quarter. Asked if he was too old to be risking a serious injury, James smiled: "Listen man, not for that 500, I ain't."

Each player on the winning side of the inaugural final, in which the Lakers will take on the Indiana Pacers, will receive a $500,000 bonus.

James was weighing up retirement after last season, but is thrilled to still be on the court.

"If you decide to retire, or whatever the case may be, you're not a part of it anymore, so it wouldn't be me leaving it on the table because I would have never had the table set," James told ESPN.

"But I'm happy that I'm here; this is a pretty cool moment, and let's see if we can capitalise on it. It's been good. It's been dope.

"We've got to finish our breakfast on Saturday. That's the most important thing."

Lakers coach Darvin Ham, meanwhile, believes the NBA's in-season tournament has injected fresh life into the early stages of the season.

"This time of the year you tend to, you don't want to admit it, but teams tend to sleepwalk through some of these games," Ham said.

"So for the league to infuse this tournament at this point and time of the year, I thought it was brilliant.

"Now being here in Vegas, it's definitely a really thick electricity that's happening that's reverberating all the way through the arena, through the teams. Everybody is excited to try to give it their best shot.

"We are just trying to build a rhythm and be the best team we can be and put our best foot forward on a daily basis. The tournament just happens to align with what we got going on in general."

It was another tough game for Pelicans talisman Williamson, who finished with only 13 points.

"I got to be better," Williamson said. "I got to be more aggressive in finding my shot. I got to do more things to get my team going. I think I was too laid back tonight."

Giannis Antetokounmpo insists the players must shoulder the blame after the Milwaukee Bucks lost to the Indiana Pacers in the in-season tournament semi-finals.

The Pacers won 128-119 in Las Vegas to take their place in the final of the inaugural competition. Indiana will face the Los Angeles Lakers in that show-piece game.

Milwaukee were the favourites heading into Thursday's matchup, but Antetokounmpo criticised the team's lack of organisation.

However, he was adamant the players, not the coaches, must take responsibility.

"The talent level we have is incredible," said Antetokounmpo, who finished with a double-double of 37 points and 10 rebounds. "But we have to be more organised.

"I feel like sometimes we're not organised at all. We don't know what we try to get from our offense, or sometimes defensively we're not sprinting back.

"We don't shoot a lot of early 3s. At the end of the day, you have to protect the ball. You have to know where the ball is. We had a lot of situations today that they got a lot of dunks, open 3s, early 3s. We have to be better.

"Nobody is going to give you anything. Like sometimes I feel like we expect just because we have great players out there, that Tyrese Haliburton or Myles Turner or Aaron Nesmith, somebody is not just going to give us the game.

"We have to be better. We have to go out there and take it. You know at the end of the day, I think we are great players, but if we don't go out there and compete, they are not going to respect us. They played their best against us.

"The players play the game. We play the game, you know? Coaches can say whatever they want to say and put us in the position to be successful, and you hope that they do that for you. But you've got to make the plays.

"It's not the coaches' fault you don't sprint back. If you're not able to execute down the stretch and you turn the ball over and you throw it to your opponent's hands, it's not the coaches' fault. You just have to take that."

Bucks coach Adrian Griffin, though, said the onus is on him.

"I've got to do a better job of getting them into some certain sets down," he said. "But we put ourselves in a position [to win].

"The first half was rocky. We made some good adjustments, but we've got to close out in the fourth quarter, which we've done very well. We just couldn't pull it off tonight."

LeBron James needed less than three quarters to score 30 points and the Los Angeles Lakers booked a spot in Saturday’s Inaugural In-Season Tournament final with a 133-89 rout of the New Orleans Pelicans in Las Vegas.

Austin Reaves had 17 points and Anthony Davis added 16 with 15 rebounds for the Lakers, who will face the surprising Indiana Pacers for the NBA Cup.

Trey Murphy led New Orleans with 14 points and Zion Williamson had 13 with just two rebounds.

The Pelicans led 30-29 after the first quarter, but James opened the second by scoring the Lakers’ first 11 points, including three 3-pointers in a row.

James had 21 points on 7-of-9 shooting by halftime with Los Angeles up 67-54. He went to the bench midway through the third quarter and should be plenty rested for the final.

The Lakers have won three straight games and 11 of their past 15.

Haliburton leads Pacers over Bucks in In-Season Tournament semifinals

Tyrese Haliburton had 27 points and 15 assists, Myles Turner added 26 and the Indiana Pacers beat the Milwaukee Bucks 128-119 to advance to Saturday’s inaugural In-Season Tournament final.

Haliburton hit a dagger 3-pointer with 50 seconds remaining to put the Pacers up 122-114 and celebrated by mimicking Damian Lillard’s “Dame time” celebration.

The Pacers, who entered the game third in the NBA in 3-point shooting, shot just 7 of 33 from deep (21.2%) but scored 72 points in the paint.

Turner scored 10 of his 26 points in the first quarter, including a monstrous dunk over Giannis Antetokounmpo.

Isaiah Jackson, Andrew Nembhard and T.J. McConnell combined to shoot 13 of 19 from the field while Indiana’s bench outscored Milwaukee’s 43-13.

Antetokounmpo had 37 points and 10 rebounds to lead the Bucks, while Lillard scored 24 and Khris Middleton added 20.

The Golden State Warriors rallied for a 110-106 win over the Portland Trail Blazers on Wednesday as Jonathan Kuminga's impressive cameo left Steve Kerr pondering more changes to his lineup.

Stephen Curry overcame a slow start to finish with a game-high 31 points as the Warriors saw off Portland at Chase Center, though their victory was far from a sure thing until Kuminga's third-quarter introduction.

Against the team with the second-worst record in the Western Conference, the Warriors looked lifeless until the 21-year-old entered the fray.

Kuminga starred with 13 points in 17 minutes, stealing the ball from Toumani Camara at a vital moment late on to kick-start a move which ended with a Curry three-pointer, making the result safe.

The Warriors are now 10-11 for the season, with injuries and suspensions – most notably Draymond Green's five-game ban for putting Rudy Gobert in a chokehold – having hampered their attempts to build any lasting momentum.

Golden State have already used nine different starting lineups this year, with only the Miami Heat naming more in the whole league, and Kerr expects the rotation to continue for the time being. 

"The puzzle hasn't fit this year," Kerr said. "We've had a lot of guys playing well, but we may have to think about moving the starting lineup around from game to game depending on who we are facing. 

"I'd still prefer to get something solid, but we haven't established anything this year. We're a quarter of a way through, so there is a lot of thought that has to go into this.

"I've really been patient and hoping to get our starting unit from the last couple of years into a good groove.

"It's easier to play and to coach when everybody knows exactly where they fit in. It's easier to play a role when there is a set rotation and the stars are playing well so the puzzle fits.

"Every night is going to be different with this team, that's what I am figuring out. We don't have roster clarity in terms of who's going to play every single night."

Curry added that the Warriors need greater flexibility in games, saying: "There have been situations this year… obviously we lost some big leads because we haven't been able to adapt quickly enough in those kinds of games. 

"It's the same thing with the coach's decisions that he has to make on a night-to-night basis."

Luka Doncic hailed an "amazing" night after surpassing Larry Bird with the 60th triple-double of his NBA career, helping the Dallas Mavericks crush the Utah Jazz 147-97 on Wednesday. 

Doncic recorded the first first-half triple-double of his career at American Airlines Center, finishing with 40 points, 11 rebounds and 10 assists in just three periods as the Mavs dominated from the off.

The four-time All-Star brought up his 60th triple-double with just under a minute remaining in the second quarter, moving past Bird to go ninth outright in the league's all-time rankings.

Asked what it meant to surpass the Boston Celtics icon, Doncic said: "It's pretty amazing. I don't know what to say, honestly. We all know who Larry Bird is, so it's pretty special."

Kyrie Irving added 26 points for Dallas, who had their highest-scoring game of this season and came up two points shy of the highest-scoring game ever in regulation.

Dallas guard Tim Hardaway Jr., who added 17 points in 22 minutes on the court, said after the win: "Luka set the tone with that, knocking down shot after shot after shot… after shot after shot after shot! I thought he was going to go 50-20-20!"

While Dallas snapped a two-game losing streak to improve to 12-8, putting them fourth in the Western Conference standings, the Jazz sit 12th at 7-14 after a performance which left coach Will Hardy furious.

"That was an absolutely horrendous performance," Hardy fumed. 

"It seemed like the Mavericks were moving at a different pace than we were from start to finish."

Joel Embiid was praised for an "effortless" shooting performance after he led the Philadelphia 76ers to a 131-126 victory over the Washington Wizards with a season-high 50 points.

The reigning NBA MVP, who also grabbed 13 rebounds, hit the 50-point mark for the sixth time in his career on Wednesday.

Washington (3-17) was in with a chance of an upset as they led in the fourth quarter but the 76ers prevailed to improve to 13-7 on the season with a key road win.

Embiid was 19 of 24 from the floor and 11 of 13 from the foul line. He also had seven assists and six turnovers in just over 38 minutes.

Tyrese Maxey added 26 points and De'Anthony Melton chipped in with 19 as Philadelphia averted a third straight loss.

"I felt like it was one of those nights where I had to be aggressive and get it going," Embiid said after the game. 

"Sometimes your team needs you to be a playmaker, but sometimes they need you to score.

"But they made passes, they made the right plays every single time and I just finished them."

Melton felt it was a game that showed how important Embiid is to the team, with the 76ers now set to play three of their next four games at home, including another clash with the Wizards on Monday.

"That's why he's the MVP," Melton said. "He's our safety valve – offensively and defensively.

"He covers up for a lot of our mistakes defensively and then offensively he can bail us out late and make some shots.

"He was just going out there effortlessly shooting the ball and scoring."

Philadelphia is fourth in the Eastern Conference standings and are next in action at home to the Atlanta Hawks on Friday.

Luka Dončić notched a triple-double by halftime and finished with 40 points, 11 rebounds and 10 assists in three quarters in the Dallas Mavericks’ 147-97 rout of the Utah Jazz on Wednesday.

Doncic grabbed a rebound with 71 seconds left in the first half and assisted on Dereck Lively II’s dunk 12 seconds later to complete the 60th triple-double of his career. That moved him past Larry Bird into sole possession of ninth on the career list.

The Dallas superstar had the first 25-point first-half triple-double in NBA history. Doncic shot 14 of 25 from the field and was 6 of 12 from long range.

Kyrie Irving added 26 points for Dallas, which had its highest-scoring game of this season and came up two points shy of the highest-scoring game ever in regulation.

Ochai Agbaji scored 21 points for the Jazz, who played without top scorers Lauri Markkanen (hamstring) and Jordan Clarkson (thigh).

Grizzlies’ Bane goes off as Pistons lose again

Desmond Bane poured in 32 of his career-high 49 points in the second half and the Memphis Grizzlies sent the Detroit Pistons to their 18th straight loss, 116-102.

Detroit’s streak is the longest single-season run in franchise history and the longest in the NBA since the Houston Rockets’ 20-game slide in 2020-21. The Philadelphia 76ers hold the NBA record with a 26-game drought in 2013-14.

Bane shot 19 of 31 from the field and 4-of-8 from 3-point range while sinking all seven free-throw attempts. He added eight assists and six rebounds.

The Pistons held a 69-61 lead midway through the third quarter, but Bane scored the next seven points.

Bojan Bogdanovic scored 22 points for Detroit, which was outscored 34-18 in the fourth quarter.

Embiid drops 50 in 76ers’ win

Joel Embiid scored a season-high 50 points and grabbed 13 rebounds to lead the Philadelphia 76ers to a 131-126 victory over the Washington Wizards.

Embiid hit the 50-point mark for the sixth time in his career, falling nine points short of his career best set on Nov. 13, 2022, against Utah.

He was 19 of 24 from the floor with a 3-pointer on two attempts and 11 of 13 from the foul line. He also had seven assists and six turnovers in just over 38 minutes.

Tyrese Maxey added 26 points as the 76ers averted a third straight loss.

Kevin Durant did not look to use a contentious timeout call as an excuse after the Phoenix Suns slipped to a 106-103 defeat to the Los Angeles Lakers.

The Suns were left furious after the referee elected to call a timeout following LeBron James' call, when the ball appeared to be loose, late in the fourth quarter of Tuesday's in-season tournament quarter-final.

With 15 seconds remaining, Davin Booker dispossessed Austin Reaves, with James swiftly requesting a timeout, which was granted.

Suns coach Frank Vogel fumed: "It's a loose ball, and you can't call a timeout on a loose ball.

"The whistle blows. I don't know why. Everything in the league is reviewable. I don't know why that can't be reviewable.

"We've got the trap, we've got the turnover, [and the] damn whistle blows. It's just frustrating."

Durant, though, did not share his coach's anger.

"That's not the ballgame," said Durant, who led the Suns with 31 points, seven rebounds and four assists.

"That's one play. It's a 48-minute game. I don't like to complain about calls.

"Sometimes the ref isn't going to get it right all the time. Sometimes it's on us to play through all that stuff and not worry about putting the game in the ref's hands."

Reaves added: "There was no call, and LeBron made a high-IQ play he's made a million times.

Vogel did, however, echo Durant's sentiment that the Suns did not do enough to win the tie and progress to Las Vegas.

"We didn't do enough early in the game," Vogel said. "The turnovers and on the glass, if we do a better job, we're not talking about a close game like that."

The Lakers will now face the New Orleans Pelicans for a place in the final of the inaugural in-season tournament, with the winner taking home the NBA Cup.

"You've got some of the most alpha male competitors in the world, and if you give us an opportunity to play for something meaningful or an incentive, then you get what you're getting," said James, who finished with 31 points and 11 assists.

"The in-season tournament is what it is, and we have an opportunity to play on a big stage, be on national television, represent our families, our communities, where we come from."

The Milwaukee Bucks will not always hit the height of their potential, but Damian Lillard suggested Tuesday's big win over the New York Knicks can be a sign of what is to come.

The Bucks ran out 146-122 winners over the Knicks in their NBA in-season tournament quarter-final.

Giannis Antetokounmpo had 35 points and 10 rebounds, while Lillard contributed 28 points, as the Bucks, who are second in the Eastern Conference, teed up a semi-final against the Indiana Pacers in Las Vegas.

Lillard warned it was too much to expect the Bucks to perform like that in every game, but he said the team have laid down a marker.

"I thought this was probably our best offensive game," said Lillard.

"That doesn't mean we're going to turn into a team that does that every night, but I do think we have that type of explosiveness.

"We can't depend on having these types of nights every time, but it's definitely a look at the kind of nights we can have offensively.

"It's been some bumps in that process where we don't play so great some nights but we're still able to win those games.

"I think now is just starting to get a little smoother, knowing where we should be on the floor, knowing how to give each other outlets, knowing how to help each other be who we are.

"It's not perfect, but I just like that we're showing improvement and it's carrying over and you can see it on the floor."

Lillard added that winning the in-season tournament would be a statement of intent.

"You come out of this thing on top, the last team standing, I think it's a pretty strong statement," he said. "It's something that everybody around the league has to respect."

"Tonight was a huge step. We wanted to get to Vegas," Bucks coach Adrian Griffin said.

"But when we get to Vegas, we've got to take care of business. We still got two games to win there."

The Los Angeles Lakers secured a spot in the In-Season Tournament semifinals on Tuesday with a 106-103 win over the Phoenix Suns, as LeBron James scored 15 of his 31 points in the fourth quarter.

James had 15 of the Lakers’ first 19 points in the final quarter and got the assists on his teammates’ other two baskets as Los Angeles pulled ahead.

Anthony Davis tallied 27 points and 15 rebounds and Austin Reaves added 20 points, including a key 3-pointer with 15 seconds left to extend the Lakers’ lead to 105-101.

Los Angeles advances to face New Orleans on Thursday in Las Vegas.

Kevin Durant scored 31 points for the Suns but came up short on a potential tying 3-pointer at the buzzer.

Bucks handle Knicks to reach semifinals

Giannis Antetokounmpo had 35 points and 10 assists to help the Milwaukee Bucks book a spot in the semifinals of the NBA’s inaugural In-Season Tournament with a 146-122 victory over the New York Knicks.

Damian Lillard added 28 points and Malik Beasley had 18 for the Bucks, who improved to 5-0 in tournament play with their ninth consecutive home win.

They set a season high in scoring, shooting 60.5 percent (23 of 38) from 3-point range and 60.4 percent overall to set up a matchup with Indiana in Las Vegas on Thursday.

Julius Randle scored a season-high 41 points on 14-of-19 shooting, and Jalen Brunson had 24 points, but the Knicks had a three-game win streak stopped.

Zion Williamson believes there is great potential in the ranks of the New Orleans Pelicans after they bounced back to defeat the Sacramento Kings in the NBA's in-season tournament.

The Pelicans teed up a semi-final tie with either the Los Angeles Lakers or the Phoenix Suns in Las Vegas, after rallying from a 15-point first-quarter deficit to win 127-117 on Tuesday.

Brandon Ingram finished with 30 points, eight rebounds and six assists in the comeback victory, while Herb Jones added 23 points for the Pelicans, who trailed by a 32-17 score less than eight minutes in before embarking on a 22-4 run to take a three-point lead early in the second quarter.

New Orleans extended the margin to 69-61 at halftime and never trailed in the final two quarters while building a lead as big as 15 points in the third. Ingram had 17 of his points in the second half, while Jonas Valanciunas posted 18 points on 7-of-11 shooting along with 11 rebounds for the Pelicans.

"This team can be so great," Williamson said. "We have a lot of potential, but we have a lot of growth to do.

"But overall, we can do something really special if everybody stays locked in. We can do something really special."

Williamson only had 10 points, but he believes it is crucial that others step up to the plate when he is not at his best.

"With the shooters we've added, it definitely does take pressure off of me," Williamson said.

"I didn't play too well, but we were still up 13, 18, late in the game. This just shows how locked in everybody is. Coach always talks about staying ready. Our guys stayed ready."

For coach Willie Green, the level of trust shown by his players was the most pleasing aspect of the win.

"The biggest thing I saw in that game was trust," Green said.

"Our guys just stuck together. They stuck together in the huddle, and they continued to make the right play over and over and over again.

When you see a team that has 29 assists and only 14 turnovers, that's a team that's continuing to trust. We want to continue to build on that."

The Pelicans' win was marred, however, by news of a fan dying after a medical emergency at Golden 1 Center.

"During the first quarter of the Kings vs. Pelicans game, a guest had a medical emergency," a Kings statement read.

"EMS immediately responded and administered CPR. Tragically, these efforts were unsuccessful and the guest passed away. The organization offers its deepest condolences to the guest's family and loved ones."

Tyrese Haliburton and the Indiana Pacers savoured "a very special" night after they saw off the Boston Celtics in the closing stages of a dramatic in-season tournament quarterfinal.

Indiana has reached the final four stage in Las Vegas and will face the winner of Tuesday's game between the New York Knicks and Milwaukee Bucks in the semifinals.

The Pacers won 122-112 on Monday, spurred on by a tiebreaking four-point play from Haliburton with 1:33 left, which delighted an electric home crowd and sparked a decisive 9-0 run.

Haliburton had 26 points, 13 assists and 10 rebounds to record his first career triple-double at the perfect time, putting his team two wins away from NBA Cup glory.

He had missed Saturday's win over the Miami Heat with a respiratory infection and conceded he felt "dead" in a first half where he struggled with his breathing, but after using an inhaler at halftime the 23-year-old was able to produce a memorable second-half performance that led his team to a famous victory.

Haliburton was thrilled to upset the odds against Boston, who blew out Indiana 155-104 in November and came into the quarterfinal with a league-leading 15-4 record.

"We have wanted to be in this situation all year – and here we are," Haliburton said, per ESPN.

"Now it's not just about being here. It's about winning.

"It feels good to win, especially in a game where nobody expected us to. The atmosphere was crazy.

"It means the world to me to represent Indiana and this organization. I don't even know if it was as much about what was at stake, as it was about what they did to us the last time. I think that left a bad taste in our mouths."

Pacers coach Rick Carlisle felt the tournament clash was like a playoff game.

"The thing about the in-season tournament is that as you advance, you're going to play two more games – win or lose in the quarterfinals – against better opponents," he said. 

"And so this is something that's great for us because we need high level competition. 

"It really is another thing that is a simulator of playoff basketball. So it really helps us. And so, coming out with the win was big for a lot of reasons that I mentioned.

"But I know this is very special to Tyrese as well."

Center Myles Turner has been with the Pacers since 2015 so is well qualified to put the atmosphere and occasion into context.

"I haven't heard it like this here in like three or four years, probably since Victor Oladipo was here," he said after scoring 17 points and adding 10 boards.

"The energy was just incredible. I think this city really started rallying around this team. The story, the backstory of it all makes it the most special.

"And the fact that he [Haliburton] got his opportunity, he is able to take it and run with it ... I mean, it's just dope to see where this franchise, where I started with to what it's becoming and what it potentially can become from the same level. 

"It's honestly, like I said, it goes back to the atmosphere. I haven't heard MVP chants, maybe when Oladipo was here, but Ty's really come in and taken over and it's fun stuff."

Jayson Tatum had 32 points and 12 rebounds for Boston, while Jaylen Brown scored 30 points and added nine boards.

But those efforts were still not enough to prevent elimination as Boston played without injured All-Star Kristaps Porzingis.

The defeat left Tatum disappointed to miss out on the Las Vegas showpiece as the in-season tournament continues to gain momentum and popularity.

"We got to just be more connected defensively," he said. "But, I mean, it's the NBA. Sometimes guys are going to make plays.

"He [Haliburton] hit some tough shots. So it's kind of two fold. Guys get paid a lot of money to play basketball, and they're pretty good.

"Yeah. I wanted to go to Vegas, I didn't want to go home. I wanted to go Vegas, so yeah, I'm mad. Next year, I guess."

Indiana's semifinal will be on Thursday, a day before Boston hosts the loser of the New York-Milwaukee quarterfinal in their next game.

Kristaps Porzingis will be absent as the Boston Celtics aim to seal their place in the last four of the NBA's in-season tournament.

Porzingis has missed the Celtics' last three games after sustaining a calf injury in a defeat to the Orlando Magic on November 24.

And the Latvian, who joined Boston from the Washington Wizards in the off-season, will not recover in time to face the Indiana Pacers on Monday.

Porzingis is averaging 18.9 points, just slightly below his career average (19.6), across his 15 games this season. Tyrese Hailburton, meanwhile, is a doubt for the Pacers.

The winner of Monday's quarter-final will head to Las Vegas for the semi-finals.
