Nick Kyrgios has complained of the smell of marijuana during his second-round US Open victory over Benjamin Bonzi on Wednesday.

The 2022 Wimbledon finalist made the claim to the chair umpire late in the second set of his hard-fought 7-6 (7-3) 6-4 4-6 6-4 win over the Frenchman at Louis Armstrong Stadium.

The chair umpire remarked that the smell could be coming from the kitchen which Kyrgios retorted with "it was f***ing marijuana".

"People don't know I'm a heavy asthmatic," Kyrgios told reporters after the match.

"When I'm running side to side, I'm struggling to breathe, probably not something I want to be breathing in in between points.

"Yeah, US Open, it's a very different vibe to everywhere else. I feel like Wimbledon was so proper. Australian Open, you kind of expect it there, being an Aussie.

"But here, it's just like noisy. Point in, point out, I can't barely hear. Half the time I can't even hear my team because it's so noisy all the time."

The latter half of Kyrgios' second-round match coincided with major drawcard Serena Williams playing on Arthur Ashe Stadium against second seed Anett Kontaveit.

"Ashe was unbelievably noisy," Kyrgios added. "I couldn't hear anything. Constant jitter. Things going off, sirens.

"In Armstrong today, hearing trains and people. For someone that's struggled to focus in my career, I'm really trying hard to put my head down and play point by point, try to dig myself out of some certain situations.

"It's hard because there's a lot of distractions. Obviously a lot of heckling going on as well. People are saying things. I got to be very careful with what I say these days."

Kyrgios' win means he will take on American J.J. Wolf in the third round on Friday and the 23rd-seed Australian, who won August's Citi Open in Washington DC, said he was feeling motivated and more professional than ever.

"This year's been amazing in so many different ways," he said. "For my tennis, I kind of wanted to almost reinvent myself, get back to the top of the game where I know I belong.

"The Wimbledon final was a turning point I think for me mentally. If I won that match, I don't know where my motivation would have been at. Losing it and being so close, it was really tough for me to kind of swallow that.

"Winning Washington, winning so many matches, I just feel like I thought the pressure would be off me after winning Wimbledon. He's a Wimbledon finalist, he's nearly-over-the-hump-type thing.

"I didn't think I'd be putting this amount of pressure on myself. Every day I come in, I watch what I eat, I try and get sleep. Like every practice session I try and have good intent. I almost don't know who I am anymore, to be honest, because that's not me.

"I feel like I'm really professional right now. I never thought that the Wimbledon final would make me that way. I thought it would be the other way, the reverse, almost a bit lax and a bit chilled with it."

Los Angeles Rams defensive tackle Aaron Donald has downplayed a brawl in their Thursday practice against the Cincinnati Bengals where he was seen swinging a Bengals helmet as a weapon.

Footage emerged of the incident from the practice session between last season's Super Bowl teams with three-time NFL Defensive Player of the Year Donald at the center of it.

The situation led to calls for a suspension, but clubs, and not the league, are responsible for overseeing the players' conduct in practice, with no ban transpiring since.

Rams coach Sean McVay played down the significance of the fracas later in the day and Donald reiterated that on Wednesday.

"It was just a practice. It was football," Donald told AP Pro Football Podcast.

"I don't really want to go back to nothing negative that happened and talk about something that happened in a practice. My main focus is Buffalo."

Donald indicated he had addressed the incident with McVay and teammates but would not be drawn on it further.

The Rams start the new NFL season against the Buffalo Bills on Thursday night.

Serena Williams says this is the most free she has felt on a tennis court in over 20 years after shocking world number two Anett Kontaveit 7-6 (7-4) 2-6 6-2 to advance to the third round of the US Open.

Williams, 40, found another gear in the deciding set as she rode the wave of momentum that came from the raucous, sold-out Arthur Ashe Stadium crowd.

While Williams rose to the occasion, Kontaveit folded, posting three winners and 11 unforced errors in the third set, allowing the all-time great to secure the victory with a break-to-love.

On the court after the match – after a recorded video message from Oprah Winfrey also aired after Monday's win over Danka Kovinic – Williams said while everyone else may have been surprised by the result, she still has supreme confidence in her abilities.

"Well, I'm a pretty good player," she said playfully. "You know, this is what I do best. 

"I love a challenge. I love rising to the challenge. Yeah, I haven't played many matches, but I've been practicing really well. 

"In my last few matches, it just wasn't coming together. I'm like, this isn't me. The last couple matches here in New York, it's really come together."

Williams admitted that she thought to herself "this could be it" after dropping the second set, but highlighted the fact that this is the first time in over 20 years that she does not feel like she has a target on her back.

"Honestly, I'm just looking at [this run] as a bonus," she said. "I don't have anything to prove. I don't have anything to win. I have absolutely nothing to lose.

"Honestly, I never get to play like this since '98 really. Literally, I've had an 'X' on my back since '99. It's kind of fun.

"I really enjoy just coming out and enjoying it. It's been a long time since I've been able to do that."

Lastly, Williams talked about what it will be like to step back out onto the doubles court with sister Venus Williams on Friday night.

"I'm so excited for doubles," she said. "It's like, it's been so long. We got to play again, we got to bring the reunion back.

"I'm excited to play with Venus, get some more practice – because I could use the matches."

Two-time Copa Libertadores champions Flamengo have put one foot in the continental decider after a dominant 4-0 win away to Argentinian outfit Velez Sarsfield in Wednesday's semi-final first leg.

Pedro bagged a hat-trick for the Brazilian club, taking his 2022 Copa tally to 11, to silence the Buenos Aires crowd who were left stunned by the scoreline.

Flamengo scored twice before the break, with Pedro opening the scoring in the 32nd minute, before running away with the game with two further strikes in the final half hour.

The victory maintains Flamengo's unbeaten run in this year's tournament, winning 10 of their 11 matches, having conceded only once in five games in the knockout stages.

The second leg will be played in Rio de Janeiro next Wednesday, with the tie winner to face either Palmeiras or Athletico Paranaense in the October 29 final in Guayaquil in Ecuador.

One-time Brazil international Pedro opened the scoring by flicking in Leo Pereira's 32nd-minute cross, before a fine team move was capped off by Everton Ribeiro from Gabriel Barbosa's cushioned pass on the stroke of half-time.

Pedro was set up by Gabriel Barbosa for his second goal in the 61st minute, finishing with a classy dink over onrushing Velez goalkeeper Lucas Hoyos.

Gabriel Barbosa pushed a good 76th-minute chance into the side netting, but 2019 Copa winners Flamengo soon had a fourth in the 83rd minute when Pedro finished off a move he started to all but put the tie to bed.

Carolina Panthers quarterback Baker Mayfield has denied saying he wants to "f*** them up" about his former side the Cleveland Browns who they will face in their September 11 season opener.

Mayfield has been given the nod as the Panthers' starting QB after a prolonged battle with Sam Darnold to start the 2022 NFL season.

Mayfield's exit from the Browns, who took him with the first pick in the 2018 NFL Draft, occurred after they traded for quarterback Deshaun Watson.

As a result, Mayfield requested that the Browns trade him, joining the Panthers in July, although he has been reluctant to criticise his former franchise publicly.

NFL Network analyst Cynthia Frelund claimed on Monday night's Around The NFL podcast that Mayfield echoed the remark to her, albeit innocuously, after last week's preseason finale against the Buffalo Bills.

"First, I didn't say it," Mayfield told reporters. "Everybody is going to write whatever story they want.

"There's history because I played there the last four years. I'm an extremely competitive person. Everybody knows that. If I wasn't wanting to win, then there would be a really big issue of me being the quarterback here.

"I want to win in everything I do. That'll never change. But it's not how I phrased it. It's not even what I said, so let's leave it at that."

He added: "I didn't even say anything. All I did was, 'Great, hope we win.' Pretty plain and simple. I'm competitive. I want to win. I don't think that should be harped on.

"That's the extent of it. It's obviously a bigger story because I haven't given the media what they've wanted me to give them this year in this offseason."

Mayfield conceded that the season opener against his former side meant something to him although he did try to downplay the narrative.

"Obviously, there's a lot of attachment there," he said. "I'm not going to sit here and be a robot and say it doesn't mean anything. It will.

"It's a great storyline. It really is because I wasn't expected to be out of Cleveland. But after Week 1, there's 16 more that really, really matter. That's how I'm approaching it."

Mayfield started 59 games in his four seasons in Cleveland and helped lead the Browns to their first playoff victory since the 1994 season in 2020. The QB went 29-30 in 59 regular-season starts with the Browns.

Serena Williams gave the celebrity-laden crowd in Arthur Ashe Stadium on Wednesday night a taste of her very best, pulling through in the third set to defeat world number two Anett Kontaveit 7-6 (4-7) 2-6 6-2.

The two-hour-and-27-minute victory sees Williams, who has announced her intention to evolve out of playing tennis after the US Open, move into the third round where she will face Australian world number 46 Ajla Tomjlanovic.

The opening set had Williams' power serving game on full display, winning 89 per cent (24-of-27) of the points when she landed her first serve fair, while producing six break point opportunities in her return game while only facing three.

She could only convert one of those break point chances, going up 5-4 with a chance to serve out the set, before handing the break straight back, leading to a tiebreaker.

Of the 11 tiebreaker points, only one went against the serve, with Williams seizing her opportunity to secure the opening frame.

As Williams' serve fell off in the second set – only winning 50 per cent of her successful first serves – Kontaveit fought her way back into the game, producing a clean set as she hit 13 winners to only three unforced errors, wrapping up the frame in a snappy 36 minutes to take it to a decider.

After holding serve to open the set, Williams then took a 2-0 lead as she was able to convert her third break point chance of the marathon 13-point game. That was followed with a 12-point game where Kontaveit was able to break back, as the 40-year-old American was visibly slowing down the longer the match dragged on.

As Williams' energy reserves began to run low, she tried to compensate with as many one-shot rallies as possible, going for sink-or-swim drives down the line and across the court – resulting in some spectacular winners, but also an increase in unforced errors.

It turned out to be the right strategy as Kontaveit continued to have trouble with Williams' power, giving up the late break again to go down 3-1 before the living legend consolidated her advantage with a hold-to-love, sending the crowd wild as they could see the finish line.

With Tiger Woods in her players' box cheering her on, Williams secured a point from a 19-shot rally as the atmosphere hit fever pitch, and despite the effort required in that point, she was able to repel another break point opportunity to hold and go 5-2 up.

Ultimately, the cauldron inside the sold-out stadium proved too much for Kontaveit, who could not find winners down the stretch. She posted three winners and 11 unforced errors in the final set, including a double-fault in her final service game as she was broken-to-love to secure the stunning result.

Data Slam: Serena continues to win the big matches

Williams has now won her last 10 grand slam matches against opponents ranked in the top-two, with her last loss coming to Justine Henin 15 years ago at the 2007 US Open.

She has also only lost three of her previous 104 US open matches when she has won the first set, and is 42-0 in the opening two rounds at Flushing Meadows.

The Chicago White Sox have confirmed manager Tony La Russa is out indefinitely as he undergoes further medical tests.

La Russa was not present for Tuesday's 9-7 loss to the Kansas City Royals after participating in pregame activities, with doctors advising him to step away from the evening game.

The 77-year-old, who was re-appointed White Sox manager in October 2020, will be absent for an indefinite time following a Wednesday morning medical evaluation requiring further testing over the coming days. The medical issue remains unspecified.

"His absence from the club will be indefinite pending the results of these evaluations," the White Sox said in a statement.

Bench coach Miguel Cairo will lead the White Sox, who have had an underwhelming season with a 63-66 record in the American League Central, in La Russa's absence.

"He was fine yesterday," Cairo said prior to Wednesday's game against the Royals. "He was feeling fine. I talked to him today. He was fine."

The Tampa Bay Rays received some good news on All-Star Shane McClanahan’s injured shoulder.

An MRI on Wednesday confirmed the initial diagnosis of a left shoulder impingement for McClanahan, which was a "best case scenario" according to Rays manager Kevin Cash. 

Cash said he’ll get a cortisone shot and could be back on the mound in as soon as 15 days. 

The Rays got a scare Tuesday when McClanahan cut short his pregame warmup in the bullpen because “something just didn’t feel right” and he ended up being a late scratch for his scheduled start against the Miami Marlins. 

''I think we made the right decision to shut it down and just catch it early,'' McClanahan said. ''When I was told ‘best case scenario,' I was very, very pleased. This could have gone a lot of different ways. For it to be what it is, it's a sigh of relief.'' 

The Rays could ill afford to lose their top starting pitcher for an extended period of time as they battle for a playoff spot with just over a month to go in the season. 

Tampa Bay, which ended up placing McClanahan on the 15-day injured list, entered play Wednesday a half-game ahead of the Seattle Mariners and one game up on the Toronto Blue Jays for the AL’s top wild-card spot. 

McClanahan, who was the AL’s starting pitcher in July’s All-Star Game, has been instrumental to the Rays’ success, having gone 11-5 with a 2.20 ERA and a 0.86 WHIP with 182 strikeouts over 147 innings in 25 games. 

Australia has named its 15-player squad for their upcoming T20 World Cup defence with uncapped all-rounder Tim David included as the major bolter.

The Australians will look to defend their T20 title in the tournament that runs from October 16 to November 13 in Australia and New Zealand.

Globetrotting T20 star David is the major surprise in the squad and the only change from last year's group that lifted the world title in UAE, replacing spinner Mitchell Swepson.

Australia's squad includes the usual suspects such as David Warner, Glenn Maxwell, Steve Smith and vice-captain Pat Cummins. Mitch Marsh is selected despite a recent ankle concern.

Skipper Aaron Finch, 35, had been under some pressure to hold his spot but is named, with the group also to travel to face India in three T20 Internationals in September in preparation. Warner will be rested for the India tour with Cameron Green taking his place.

National Selection Panel chair of selectors George Bailey said: "This is a similar squad to that which became the first Australian’s men’s team to win a T20 World Cup who are now very excited about playing the tournament at home.

"Mitchell Swepson was unlucky to miss out based on conditions in the UAE at the last World Cup where we planned for tired, spinning wickets compared to what we would expect are good batting conditions along with the larger grounds in Australia.

"Tim continues to establish himself with some quality performances in leagues around the world, earning a place in the squad. He is a highly gifted, natural ball striker who will add extra batting depth to the group which has had a lot of success in T20 cricket.

"We expect him to play a similar role to that he has been playing in the past few years."

David, who previously represented the country of his birth Singapore in 14 T20Is in 2019 and 2020, has impressed in global T20 leagues including with the Mumbai Indians in the IPL, the Southern Brave in The Hundred and the Hobart Hurricanes in the Big Bash League.

The 26-year-old has amassed 1,874 runs at a strike rate of 168.4 in 86 T20 games over the past two years in a late-overs batting role, with part-time off-breaks.

David's strike rate of 216.28 in eight matches with the Mumbai Indians earlier this year was the highest by any player to have faced at least 50 balls in a single IPL season.

Josh Philippe, Ben McDermott, Sean Abbott, Jhye Richardson and Swepson were among the unlucky players to miss out on selection.

Australia faces India in the first of their three T20Is on September 20 in Mohali, with their first World Cup match against New Zealand in Sydney on October 22.

Australia's T20 World Cup squad: Ashton Agar, Pat Cummins (vc), Tim David, Aaron Finch (c), Josh Hazlewood, Josh Inglis, Mitchell Marsh, Glenn Maxwell, Kane Richardson, Steve Smith, Mitchell Starc, Marcus Stoinis, Matthew Wade, David Warner*, Adam Zampa. 

* Will be replaced by Cameron Green for three T20Is, September 20-26, in India

Cameron Smith said he retains hope of featuring at the majors despite joining LIV Golf, as he labelled the lack of world ranking points on offer on the breakaway tour "unfair".

Smith, the current world number two, became the highest-ranked player to join the controversial Saudi Arabia-backed circuit on Tuesday, when he was announced as one of six new players ahead of this week's event in Boston.

The Australian, who clinched his first major title when winning the Open at St Andrews in July, joined compatriot Marc Leishman, as well as Joaquin Niemann, Cameron Tringale, Harold Varner III and Anirban Lahiri in signing up to the Greg Norman-headed tour.

Having reportedly agreed a deal worth over $100million to sign for the LIV Series, a decision which will earn him an indefinite suspension from the PGA Tour, Smith believes barring the circuit's players from majors is unfair on fans. 

"I hope that these world ranking points will sort themselves out before my exemption is up. I think to the fans of major championship golf, it may be a little bit unfair on them," Smith said.

"I think, you know, majors are about having the best guys in the best field on the best golf courses and hopefully we can sort that out.

"I haven't resigned my membership on the PGA Tour. I think my life has definitely changed over the last couple of months after the Open, I've had a few phone calls with players. 

"It has been a little bit different, but this, for me, was the right decision. I think this is the future of golf. I think it's been the same for a very, very long time and needs to be stirred up a little bit."

Aged 29 and ranked second in the world, the signing of Smith arguably represents one of the greatest coups managed by LIV to date, and he is hopeful the new circuit will soon be able to award rankings points.

"I think it's really a shame that we're not getting world ranking points out here," he added.

"I think, you know, to have 48 of the best guys around the world playing and not to get world ranking points, I think is perhaps a little bit unfair."

Meanwhile, Smith admitted upon joining LIV that the circuit had made him "an offer I couldn't ignore", but says being able to enjoy more time at home and play in his own country were also key motivations.

"Yes, it was a business decision as well. But you know, there's so many positives to come out of this thing," Smith said.

"For me, I haven't been back in Australia for three years. To spend more time at home, you know, not miss it out on friends' and family's weddings and you know, a couple of my friends have had kids over the last four or five years that I still haven't met. So that's going to be a part of my life that I can't wait to get back."

Asked whether there was anything the PGA Tour could have done to prevent his switch, Smith added: "Not particularly, to be honest. I think for me the biggest attraction was spending more time at home, getting that part of my life back. 

"It's something that I've really missed. I think obviously the pandemic that we've had over the last couple of years didn't really help out."

Andy Murray is a "legend" of the sport who Matteo Berrettini knows he must play his best tennis against in the US Open third round.

Berrettini had to come from behind to beat Hugo Grenier on Wednesday at Flushing Meadows, setting up a fourth career meeting with Murray.

Like Berrettini, former world number one Murray came from a set down to defeat Emilio Nava 5-7 6-3 6-1 6-0.

Berrettini holds a 2-1 lead in his head-to-head series with Murray, who won the first match between the pair in Beijing in 2019.

Murray lost to Berrettini as the Italian went on to win at Queen's Club in 2021, with the Scot going down to the 26-year-old again in the final in Stuttgart earlier this year.

"We played in different conditions. We played 2019 in Beijing, so was hard, but best-of-three. Then twice on grass. All the matches were great fights," Berrettini said in a press conference.

"I think obviously Andy now is in way better shape than he used to be, especially last year. He's a legend of the sport. I think it's going to be a great match, a tough match for me, but feeling confident. I always like to play here, especially in big stages, big matches like the one I'm about to play. Yeah, I think it's going to be a tough one, but I'm ready."

Berrettini also revealed he and Murray have practiced together, though he does not think that will help much in Friday's tie.

He said: "We're friends, but we're not like best friends. A good relationship.

"He had a crazy hip surgery. Everybody saw it. It's not easy to come back, especially when he was number one in the world. Mentally it must have been, like, really tough for him. But I think it's inspiring the will that he has, the love that he has for this sport. I always admired that.

"We often practice together, as well. When I was a kid I was watching him on TV, for me it's still a dream coming true playing against this kind of player.

"I remember 2016 he played against Paolo Lorenzi here. My brother, he played quallies here, the juniors. I was like, Wow, you're playing next to Andy, and now I'm playing against him. It's something that I really appreciate. That's why I'm even happier for the match now I'm going to play.

"But it doesn't matter. When you play Andy Murray, you're playing Andy Murray. You have to play your best tennis."

Bayern Munich new boy Matthijs de Ligt is quickly adapting to life in Germany, as he hailed the mentality of the Bundesliga giants.

De Ligt, signed from Juventus in a €67million transfer prior to the season, started on Wednesday as Bayern went on to thrash lower-league Viktoria Koln 5-0.

Maiden Bayern goals from Ryan Gravenberch and Mathys Tel gave Julian Nagelsmann's team a 2-0 lead, before second-half strikes from Sadio Mane, Jamal Musiala and Leon Goretzka finished the rout.

And De Ligt believes a defining characteristic he has noticed since arriving in Munich is Bayern's ability to maintain focus in matches they could comfortably cruise through.

"Every game is difficult, even if you play against Viktoria Koln today with a lot of fans here," he said.

"It's always difficult, you have to be concentrated every minute, because you know if you're not concentrated you can get a goal against.

"You feel immediately when you come here – it was the same with Ajax and Juventus – you feel that they want to win, and they want to win big.

"They want to be concentrated at every second, and that for me is really important, and can make me a better player."

When asked why he believes Bayern's new recruits have hit the ground running, De Ligt said: "Yeah, because I think we have a lot of good players, and it's really clear for everybody, also the new guys, how to play. 

"You see the new guys today – Mathys scored a goal, I think Ryan made a goal, and Sadio has already scored a lot of goals.

"I think we're all adapting well, and obviously the help of the team-mates is really important."

Napoli sporting director Cristiano Giuntoli says the Serie A outfit have never made a concrete offer for Cristiano Ronaldo, as the striker looks increasingly likely to stay at Manchester United beyond the end of the transfer window.

Ronaldo reportedly declared his intention to leave Old Trafford after United failed to secure Champions League qualification last season, and with Napoli back among Europe's elite after finishing third in Serie A last term, southern Italy was touted as a possible destination.

Despite Ronaldo only making one Premier League start this season – in a humiliating 4-0 loss at Brentford – United have continually reaffirmed their desire to keep him.

On Wednesday, Erik ten Hag declared he and Ronaldo were "on the same page" and claimed the Portuguese legend remained happy at Old Trafford.

With the transfer deadline fast approaching and the likes of Atletico Madrid and Bayern Munich ruling out a deal for Ronaldo, his options appear to be dwindling.

And while Giuntoli emphasised his respect for Ronaldo, he told DAZN a move to Naples had never been on the table. 

"He is an extraordinary player and we can only exalt him," he said.

"There is nothing true, we have an excellent relationship with his agent but there has never been anything concrete."

Meanwhile, Ronaldo's former Real Madrid team-mate Keylor Navas had also been linked with a move to Napoli, but Giuntoli ruled out signing another goalkeeper after Luciano Spalletti's men brought in Salvatore Sirigu.

"We have two goalkeepers and they are very good, so at 99 per cent [chance], we will keep the current squad," he added.
