For the first time since 2005, the United States will be represented by three players in the men's singles quarter-finals of a grand slam.

Tommy Paul's win over world number 25 Roberto Bautista Agut on Monday ensured his place in the last eight, where he will face compatriot Ben Shelton.

With Sebastian Korda, who defeated Daniil Medvedev in round three, ticking off another top-10 opponent in the form of Hubert Hurkacz, the USA has three male players in the last eight of a major for the first time since the 2005 US Open, when Robby Ginepri, Andre Agassi and James Blake reached the quarters.

It is the first time the USA has had three representatives in the Australian Open quarter-finals since 2000, when Agassi, Pete Sampras and Chris Woodruff made it that far.

While Korda will face Karen Khachanov for a place in the semi-finals, Paul will go head-to-head with Shelton, the world number 89.

Shelton is the lowest-ranked American player to reach a major quarter-final in over 22 years, since Todd Martin at the US Open in 2000, and the lowest-ranked American to get so far in Melbourne since Michael Chang in 1996.

The 20-year-old has already beaten one compatriot, having defeated J.J. Wolff in a five-set thriller in his last match.

Meanwhile, it is the first time since 2006 that no Spanish male players will feature in the quarter-finals at the Australian Open.

Novak Djokovic charged into the quarter-finals of the Australian Open with a straight-sets demolition of Alex de Minaur.

The nine-time champion was outstanding on Rod Laver Arena, starting the second week with a ruthless 6-2 6-1 6-2 victory over Australian De Minaur.

There were no signs of a hamstring injury that Djokovic has been nursing, other than strapping on his left leg, as he booked a last-eight meeting with Andrey Rublev.

The tournament favourite, going for a record-equalling 22nd grand slam title, did not face a break point as he sealed a dominant victory in just two hours and six minutes at Melbourne Park on Monday.

An aggressive Djokovic took complete control after De Minaur was broken to love when he netted to go 4-2 down, the Serb wrapping up the first set when his opponent overcooked a forehand.

The fourth seed won nine games in a row in a one-sided second set, producing an exhibition of returning with pinpoint accuracy off both wings and serving superbly.

Djokovic was relentless, the depth of his groundstrokes enabled him to dictate rallies, and the 35-year-old produced a huge second serve followed by a backhand winner to go two sets up in just an hour and 15 minutes.

The Belgrade native was in no mood to hang around, breaking in the first game of the third set by racing to return a De Minaur drop shot and going a double break up in a flash.

De Minaur had no answer to the brilliance of Djokovic and although he was able to get on the board at 4-1, he was heading for the exit after sending a vicious serve high and wide.

Djokovic closing in on Agassi record

This was Djokovic's best performance of the tournament as he ominously marched into his 13th Australian Open quarter-final and the last eight of a major for the 54th time. 

Djokovic has 25 Australian Open wins in a row, the joint-second longest run and one behind Andre Agassi's record streak of 26, and was also his 86th main draw win at the Australian Open, his joint-highest tally in a single ATP-level tournament (level with Wimbledon).

Royce O'Neale says his Brooklyn Nets team-mates are all stepping up to the challenge after his late three-pointer proved decisive against the Golden State Warriors.

The Nets claimed a second straight win on Sunday, with O'Neale's three-pointer with less than 30 seconds left on the clock nosing them into a two-point lead.

Kyrie Irving, the team's talisman in the absence of the injured Kevin Durant, scored two free throws with 14 seconds remaining to seal a 120-116 comeback victory at the Chase Center.

Golden State had been leading 106-93 midway through the final quarter on Sunday, and O'Neale hailed the Nets' attitude and self-belief.

"There's a lot of confidence going around," O'Neale told reporters.

"Everybody's taking the challenge, stepping up, finding out ways to win games."

Irving was key, teeing up O'Neale's crucial three-pointer to cap a ninth assist of the game. He finished with 38 points and seven rebounds.

"Kyrie had been getting to the basket, hitting tough shots and at that moment, he drove, two people double-teamed and he found me open," O'Neale said.

"I just needed to have the confidence to knock it down."

Irving added: "They did a great job of staying on my body, keeping the game physical, making it tough.

"I felt like my team-mates had a lot of great looks, drawing the defense to lose their man.

"Royce being wide open, I felt like that was the best shot for our team, so I gave up the ball, trusted him to make it and luckily it went in."

The Nets are fourth in the Eastern Conference, while the Warriors – reigning NBA champions – are down in 10th in the West after suffering a sixth loss from their last nine games.

Magda Linette revealed "emotional management" has been key to her best grand slam singles run after upsetting Caroline Garcia to move into the Australian Open quarter-finals.

The unseeded Pole beat fourth seed Garcia 7-6 (7-3) 6-4 on Rod Laver Arena on Monday to move into the last eight for the first time.

Linette had never been beyond the third round of a major before this tournament, but she will face Karolina Pliskova for a place in the semi-finals.

The world number 45 will celebrate her 31st birthday next month and feels she is benefitting from being more mature after breaking new ground in her 30th main-draw appearance at a grand slam.

She said: "We worked a lot actually about my emotional management. I think dealing with some kind of losses, but not necessarily match losses, just even throughout the match losses, like small mistakes here and there.

"I think I've never really dealt with them very well. They carried over later on for next point, then another one. It was taking me just too long to get over them.

"I think of course we work so much on my game. We worked a lot on changing the directions and the depth of the ball.

"But I think this approach of really trying to look a little bit different, grow up a little bit emotionally, like that was a big thing for us as a team. All of us approached it. It wasn't only me, but it was the coaches that brought this to me."

Asked how she works on emotional control, Linette added: "I think it's just how do you try to approach the defeats and the mistakes, and are you making the right mistakes, can you then recognise it and move on and deal with them a little bit better. I think I was just getting too negative and too harsh on myself because I feel I'm quite demanding.

"On the other hand when you try to go to that other spectrum, when you're okay with everything, it's also not the best. You really need to stay on top of things and be proactive with it, which ones you're doing good and not.

"I think recognising it, you try again and again and again. Eventually you start recognising which ones were the right ones to deal with.

"It's very difficult. I'm [almost] 31 and I'm just getting it right, so obviously it was one of the toughest things for me. But I'm happy. I'm happy that I have this opportunity, that actually I tapped into something that finally I'm breaking something that you can't really measure it in any way. For me, it was something really difficult to change."

It was a game of two halves at Moda Center as the Los Angeles Lakers overturned a 25-point deficit to beat the Portland Trail Blazers on Sunday.

When the Lakers went in trailing by 25 at the half, they had just experienced the wrong side of the joint second-biggest scoring margin in one quarter since the NBA added the three-point arc in 1979.

Portland outscored the visitors 45-13 in the second quarter, but LeBron James and his team-mates would not lie down.

The Lakers came back to register 75 points in the second half, while only allowing 41, turning around the 25-point deficit to win by nine.

"I guess it's only one or two ways, you can either go out and you can lay down and get ready for the next game or you can see what happens in the third quarter, make a game of it," James said after the victory.

"And for us as competitors, and our team and our makeup this year, we're not a lay-down team. That's just not the makeup of our club."

James scored 37 with 11 rebounds as he closed in further on Kareem Abdul-Jabbar's all-time scoring record, while Thomas Bryant added 31 with 14 rebounds as the Lakers produced their second-biggest half-time deficit comeback win in franchise history.

"They jumped on us and knocked us down,” James added. "Thank God for the standing eight count."

Aryna Sabalenka is hoping she can move to another level in a "new beginning" this year after beating Belinda Bencic to reach a first Australian Open quarter-final.

The fifth seed from Belarus saw off Bencic 7-5 6-2 on Rod Laver Arena on Monday and will face Donna Vekic in the last eight.

Sabalenka has not dropped a set in her four matches in the first grand slam of the year at Melbourne Park and has been installed as the favourite to take the title after Iga Swiatek's exit.

The 24-year-old played in a second successive US Open semi-final last year but has never made it is far as a championship match at a major.

Sabalenka won the Adelaide International 1 before heading to Melbourne and is optimistic she can kick on in 2023.

She said: "I want to believe that the way I'm working right now, the way I'm on the court right now, this is the new beginning, and this is the next step. So I really want to believe that it's going to really help me."

Sabalenka has endured struggles with her serve, but appears to have put that behind her after addressing the issue.

She added: "I worked a lot on my serve. I was keep trying, keep believing, keep changing. Then I worked on my, like, biomechanics.

"Basically that's it. But I was doing everything. I thought it's mentally, but it wasn't. We changed a lot of things on how we work on my serve. We tried to work more, less. We tried so many different things.

"In the end of the season when I start working with the biomechanics guy, he helped me a lot. I think from there, everything started to kind of get on that level."

Croatian Vekic ended 17-year-old Czech Linda Fruhvirtova's impressive run with a 6-2 1-6 6-3 victory.

Shai Gilgeous-Alexander plays the game at his own pace, according to Oklahoma City Thunder head coach Mark Daigneault after his star player helped them break the Denver Nuggets' winning streak.

Denver had put together nine victories in a row, and were unbeaten in 16 at home before the Thunder overcame them 101-99 at Ball Arena on Sunday.

Gilgeous-Alexander led the way as he scored 34 points, with five rebounds and five assists as OKC made it five wins from six games and moved onto 23-24 for the season.

The decisive basket came from Gilgeous-Alexander with 9.2 seconds remaining and Daigneault praised the Canada international guard's composure under pressure.

"He's got some poise in those situations," Daigneault said of the 24-year-old. "The game slows down for him. He's got great confidence and he's always at his pace, even in the most pressure situations."

It was the first time in over a month that the Thunder had limited an opponent to under 100 points, and Daigneault paid tribute to the Nuggets – who were again without Nikola Jokic due to a hamstring issue – and his team's ability to get past them.

"I thought we did a really good job, played really good situational basketball down the stretch of the game," he said. "Denver were really good honestly, we especially had a hard time getting anything going offensively, but the guys stuck together.

"That's a tough place to play and it was a grind, so I was really pleased with the guys tonight."

Gilgeous-Alexander is one of just five players in the league to average more than 30 points per game this season (30.7), and he believes OKC are only going to improve.

"We're getting better," Gilgeous-Alexander said. "And we're in it more often, we've played a lot of close games for a few years now and we're just going to keep getting better in those moments... really trying to get better from our mistakes in every moment we're in."

Christian McCaffrey says rookie quarterback Brock Purdy no longer surprises him after another standout display in the San Francisco 49ers' 19-12 win over the Dallas Cowboys in Sunday's NFC Divisional Round game.

The 49ers advanced to their second-straight NFC Championship Game, and third in the past four seasons, with the victory.

Purdy, who only got his chance as starting QB following injuries to Jimmy Garoppolo and Trey Lance, completed 19 of 29 passes for 214 yards, with the 49ers focusing on their run game to combat the Cowboys' strong defense.

Last week Purdy became the first rookie to throw for 200 yards with no interceptions in a postseason game and he backed that up again.

The 23-year-old quarterback is now 7-0 in starts this season, with 14 touchdowns and two interceptions, and has a legitimate claim to being the 49ers' starting quarterback next season.

"You see it every day in the day he prepares, you see it in practice, and in games, he has just been an impressive guy to be around in the huddle," McCaffrey told reporters about Purdy. 

"I'm not shocked anymore – it's just who he is now."

McCaffrey scored the game-winning touchdown to cap a drive in which Purdy linked up with George Kittle, who hauled in a superb catch for a 30-yard gain.

"That was unbelievable," McCaffrey said. "That was one of the best catches I've ever seen.

"That's a special player doing special things. And plays like that definitely boost momentum."

Kittle said he was not the primary for the play where he juggled Purdy's threaded pass, with the QB intending to hit receiver Brandon Aiyuk on a crossing route, with Deebo Samuel and Kyle Jaszczyk his other options. Instead, with none of those options open, Purdy improvised.

"I'm not in the read at all," Kittle said. "Brock is a good quarterback who keeps his eyes up when the play is falling apart and his No. 1 and his No. 2 wasn't open so for him to look back inside to see a white glove hand fly up and give me a shot at the ball, that's just really good quarterback play."

Niners head coach Kyle Shanahan did not get carried away with Purdy's game, in a contest that he expected to be tight against the Cowboys.

"He made a number of plays today," Shanahan said. "By no means was anything perfect, for the whole offense and the whole team, but it seemed like playoff football in that game.

"We were going against a team we've been watching all week, and we had a feeling it would be this type of game. That's why we were stressing the run game on both sides.

"We were stressing to protect the ball and try to get turnovers – we accomplished both of those things – but you do that stuff and you still have to make a number of plays."

San Francisco will face the Philadelphia Eagles next Sunday for a place at Super Bowl LVII.

Dallas Cowboys quarterback Dak Prescott accepted responsibility for his side's 19-12 defeat to the San Francisco 49ers in the NFC Divisional Round after throwing two interceptions.

The Cowboys extended their losing run in Divisional Round games to 7-0 since 1997 as they were eliminated from the playoffs by the 49ers for the second straight season on Sunday.

In a game where both teams' defenses shone, Prescott completed 23 of 37 passes for 206 yards with one touchdown but two interceptions.

The two picks, from Fred Warner and Deommodore Lenoir, led to six points for the 49ers, which was telling given the final margin.

"Those are throws you can't have, not in the playoffs," Prescott said. "Not when you're playing a team like that [and] on the road. No excuses for it. Those are 100 per cent on me."

Prescott had a career-high 15 interceptions in the regular season, becoming the first QB to tie or lead the league while missing five or more games.

The Cowboys QB also finished the season with his sixth multi-interception game, tied for most in the NFL.

Prescott labelled his interceptions as "ridiculous" and vowed that that total would never be so high again.

"On the first one, I hitched one too many times with [Michael Gallup]," he said. "Understandably, hitching three times, thought I was gonna go on a scramble but the guy just came back to the ball and made a play.

"I've gotta throw that one away or use my feet and get out of the pocket. On the second one, the nickel [cornerback] squeezed, and I tried to throw it to CeeDee [Lamb], but the [defender] was able to make a play on it. He tipped it in the air and to the [middle linebacker]."

Cowboys owner Jerry Jones said he felt "sick" after another playoffs exit, while head coach Mike McCarthy lamented their inability to convert on offense.

"We knew it was gonna be a slugfest," McCarthy said. "We just didn't get enough. You can go through the decisions, the statistics, but I think, defensively, we did a really good job, for the most part.

"Would we like to have a couple more snaps? Yes. Would we like to have a couple more third-down conversions on offense? Yes, we could've used those, too.

"Just extremely disappointed. This has been an incredible journey with this group of men, we just came up short tonight to a very good football team."

The Golden State Warriors blew a 12-point fourth-quarter lead at home as the Brooklyn Nets prevailed 120-116 after 38 points from Kyrie Irving on Sunday.

The Nets outscored the Warriors 22-6 after the reigning NBA champions had led by 12 with 5:42 remaining in the fourth quarter.

Irving scored a game-high 38 points, making five-of-seven three-point attempts, with seven rebounds and nine assists. Irving's performance was his third 30-point game in his past four.

Nic Claxton added a career-high 24 points with 15 rebounds and three blocks, while Ben Simmons contributed a game-high 11 assists. Royce O'Neale, who had 16 points, scored a go-ahead three-pointer with 27.1 seconds remaining.

Stephen Curry top scored for Golden State with 26 points, making four-of-eight from beyond the arc, along with six rebounds and seven assists.

Jonathan Kuminga added 20 points off the bench, while center Draymond Green had 11 rebounds and seven assists.

The Warriors' home loss means their record at the Chase Center falls to 17-6, having managed 3-2 on their recent road trip where they have struggled throughout this season.

Lakers complete stunning second-half turnaround

LeBron James scored 37 points with 11 rebounds while Thomas Bryant added 31 points as the Los Angeles Lakers stormed home for a 121-112 win over the Portland Trail Blazers.

The Lakers had trailed 71-46 at halftime after the Blazers put up 45 second-quarter points, but rallied in a remarkable second-half turnaround to improve to 22-25.

Bryant had 14 rebounds to go with his 31 points, while Dennis Schroder contributed 24 points. Anfernee Simons scored 31 points for Portland, with Damian Lillard adding 24.

OKC snap Nuggets' win streak

Shai Gilgeous-Alexander hit an eight-footer with 9.2 seconds remaining to end the Denver Nuggets' nine-game win streak as the Oklahoma City Thunder won 101-99. 

The Nuggets were without back-to-back MVP Nikola Jokic for the second straight game with tightness in his left hamstring, with Jamal Murray top scoring in his absence with 26 points and nine assists. Murray missed an attempt on the buzzer to force overtime.

Gilgeous-Alexander finished the game with 34 points on 13-of-21 shooting with five rebounds, five assists and two blocks, while Josh Giddey added 18 points and nine rebounds. The result also ended Denver's 17th game win streak at home.

The San Francisco 49ers booked their place in the NFC Championship game after emerging 19-12 winners in a defensive struggle against the Dallas Cowboys on Sunday.

Ranked as the NFL's two best defenses in the regular season based on DVOA, the respective defensive units were both at the top of their game early, with the first four drives resulting in three punts and an interception.

It was Dallas quarterback Dak Prescott who threw that interception, and it was a sign of things to come in what was a day to forget for the Cowboys' franchise centrepiece.

Prescott put Dallas ahead with a touchdown pass to Dalton Schultz in the second quarter, but it would be their only touchdown of the game as they had to settle for only two field goals in the second half.

The 49ers led at half-time thanks to three Robbie Gould field goals, and after Brett Maher made one for the Cowboys in the third period to tie things up, star running back Christian McCaffrey forced his way into the endzone with the first play of the fourth quarter to give San Francisco a 16-9 lead.

After the two sides traded field goals, the Cowboys would get two chances to march down the field for a potential game-tying touchdown, but they would end in disappointment after a three-and-out left not enough time for Prescott to complete a miraculous comeback.

Prescott completed 23 of his 37 passes for 206 yards, one touchdown and two interceptions, while his rookie counterpart kept things far cleaner.

Brock Purdy finished 19-of-29 for 214 yards and no turnovers, but it was George Kittle who was the star for the 49ers. He led all San Francisco receivers with five catches for 95 yards, including a crucial, juggling, 30-yard reception on the game-winning touchdown drive.

The 49ers will play the Philadelphia Eagles next, with a place in the Super Bowl on the line.

Dallas Cowboys running back Tony Pollard was carted to the locker room and ruled out of Sunday's Divisional round clash against the San Francisco 49ers after suffering a high ankle sprain.

The injury occurred late in the second quarter as the Cowboys were driving with the score tied at 6-6, after a Dalton Schultz touchdown catch was answered by a pair of Robbie Gould field goals for the 49ers.

On an eight-yard catch-and-run over the middle of the field, Pollard was tackled from behind by Jimmie Ward and had his foot get trapped in an awkward position on the way down.

He was immediately taken back to the locker room and subsequently ruled out, and Cowboys quarterback Dak Prescott threw his second interception of the game on the very next play.

The 49ers capitalised and kicked their third field goal of the first half to head into the break leading 9-6, although Brett Maher was able to answer for the Cowboys to tie things up six minutes into the third period.

The Cincinnati Bengals revelled in causing problems for those who had formed plans for a neutral site AFC Championship Game as they defeated the Buffalo Bills to secure another road game at the Kansas City Chiefs.

Victory for the Bills on Sunday, due to the cancelled regular season game between the teams when Damar Hamlin suffered a cardiac arrest, would have seen them meet the Chiefs in Atlanta.

The NFL had even set in motion ticket sales, which did great business with the game just a week away, but the alternative plan will not now be required after the Bengals won 27-10 in Buffalo.

Joe Burrow had the Bengals in control from the outset, and he had advice for those who had planned to see the Bills play the Chiefs.

"Better send those refunds," he told CBS.

Coach Zac Taylor added at a news conference with a grin: "We had our minds set to go and play in Kansas City.

"It is tough, because they have to formulate the plans for coin tosses, they have to formulate the plans for neutral site games, and we just keep screwing it up for everybody.

"I hate that for the people who have to endure all those logistical issues. We just keep screwing it up, so I'm sorry."

The Bengals won in Kansas City in last year's AFC Championship Game, and Taylor has no doubts they are capable of a repeat.

"We're built for this," he said. "It doesn't matter what anybody thinks about us.

"We don't care who's favourite and who's not; we're built for this. We're excited to go on the road to Kansas City."

The Bills had been 13-1 in home playoff games in the Super Bowl era, but that record merely provided a source of motivation for Taylor's team.

"In our whole team, you just look at the leadership in every position," he said.

"We talked about last night how they were 13-1 in the playoffs, the best home winning percentage in NFL history. I wanted to show that to the team, because I knew what that would do to them.

"It wouldn't put fear in them that 'oh my God, we're walking into an environment that people don't win in', it was completely the opposite for our guys. It was."

Burrow completed his first nine passes for 105 yards and two touchdowns, putting the Bengals 14-0 up before the Bills had a first down.

"He's the greatest," Taylor said. "He does a great job leading this team, managing situations. The bigger the moment gets, the calmer he gets, and the team feeds off that."

But Burrow was keen to deflect praise onto the offensive line, which was missing key personnel but ensured the quarterback took only a single sack.

"It was one of their best games of the year – rushing, pass blocking," Burrow said. "It might be our most complete game of the year as a team."

Burrow, like Taylor, is confident of the team's chances against the Chiefs, believing they are better now than they were when winning that game last year.

"I think we're a more complete team, I think we're a better team," he explained. "We just seem to make plays when it counts. That's all there is to say.

"I think our O-line is better, I think our run game is better, I think our defense is better, I think our special teams is better. We're just overall a much better team than we were last year."
