US Open

Carlos Alcaraz celebrated his US Open win on Sunday in epic fashion ... first, he doused himself in champagne -- and then he hit a New York hot spot and partied with models!!

The 22-year-old Spaniard beat Jannik Sinner 6-2, 3-6, 6-1, 6-4 at Arthur Ashe Stadium as President Donald Trump watched from the stands ... and before he left the venue, he popped some serious bubbly with his team.

Check out footage from his locker room celly -- Alcaraz surprised his pals with a massive container of booze, but they were armed with their own bottles ... and it wasn't long before everyone, and everything, was covered in alcohol.

1:12 PM PT -- More video from the US Open shows not everyone was stoked about President Donald Trump's appearance ... 'cause a number of people also booed him before the National Anthem began.

He's a pretty divisive president, obviously -- so not really a shock here.

President Donald Trump turned the US Open into his own rally ... walking into the stadium to a wave of cheers as the men's championship match was about to begin.

The President strolled into a luxury suite just before 2 PM Sunday -- moments before the men's singles final kicked off -- and fans in the surrounding boxes broke into loud applause as he took his seat. Trump, looking relaxed, waved to the crowd before settling in to watch the showdown on the court.

But his appearance wasn't without controversy because the U.S. Tennis Association sent out guidance to broadcasters ahead of time, warning them not to televise any crowd reactions connected to Trump's arrival.

It's the final weekend of the US Open, and we've seen plenty of talented athletes putting blood, sweat, and tears into their performances ... although we managed to catch a few funny faces along the way!

And hey, when superstars like Venus Williams and Alex De Minaur are out there giving everything they've got for the game, you can't blame them for losing control of their expressions for a bit!

Naomi Osaka's loss to Amanda Anisimova at the US Open means fans won't get to see her final custom Labubu plan ... but the designer behind her viral figurines tells TMZ Sports she'd love to still bring the vision to life.

Osaka's tournament run introduced viewers to her new friends like Billie Jean Bling, Andre Swagassi and more ... with the Japanese superstar debuting a new bedazzled monster based off a different tennis legend each round she advanced.

Kerin Rose Gold -- the mastermind behind the "Lablingblings" -- spoke with us about the popularity her products attracted ... and she admitted she's gotten more buzz over the past few days than the time she got name-dropped by Rihanna in an interview.

Iga Swiatek was in no mood to discuss taking a break from tennis following her US Open exit on Wednesday ... getting into a heated exchange with a reporter who suggested she needed to regroup.

Swiatek was fielding questions from the media after losing to Amanda Anisimova ... when she was asked, "how tired are you at the moment?"

Based on her reaction ... the 24-year-old wasn't the biggest fan of the question -- saying "Well, I don't know, it's not like my matches were exhausting here."

The Polish CEO who went viral after essentially snatching a tennis pro's hat away from a child at the U.S. Open seems to be offering up an apology ... according to multiple reports.

A statement apparently from Piotr Szczerek -- head of the DROG-BRUK stone paving company in Poland -- is going around online ... and, in it, the CEO says he wants to "unequivocally apologize" to the kid and his family.

Szczerek says he takes responsibility for his "poor judgment and hurtful actions" ... adding he never intended to steal Kamil Majchrzak's hat away from a young fan.

A young tennis fan was left devastated after some dude yanked Polish tennis player Kamil Majchrzak's hat from his reach ... but thanks to the internet, this story has a happy ending!!

It all went down as Majchrzak was signing autographs after his second-round win against Karen Khachanov at the US Open on Thursday. As he went to hand his cap to a kid in the front row, an older man took it instead ... and you can see the sadness take over his face.

The kid tried to get his attention, but to no avail. At least the guy had the courtesy to hand his Sharpie back ... but he ended up putting the lid in a woman's bag.

Emma Raducanu traded in her racket for a ribeye on Wednesday night ... celebrating a big win in the US Open with a steak dinner!

TMZ Sports has learned ... the 22-year-old tennis star hit up Benjamin Steakhouse in Midtown Manhattan following her big second-round victory over Janice Tjen -- and she and some pals enjoyed a lavish meal.

We're told they feasted on several ribeyes and filet mignons ... along with sides of the eatery's famous creamed spinach and Canadian bacon.

Tensions were high at the US Open on Wednesday after Taylor Townsend defeated Jelena Ostapenko in straight sets ... as the two got into a heated confrontation that was all caught on camera.

The beef started as the two shook hands at the net ... when it appeared Ostapenko said something that set Townsend off.

"You should learn how to take an L," Townsend appeared to respond.

Ben Shelton's toughest moment from the US Open didn't come from one of his opponents on the court ... but from his girlfriend during a postgame media session -- 'cause Trinity Rodman snuck in a savage question about his "slow" serves!!

Shelton met with the media after he advanced to the third round with a win over Spain's Pablo Carreño Busta in straight sets. Just as he was about to wrap up his day, Rodman -- who was present for the Q&A -- was able to ask one last question, much to her man's surprise.

"So, how did it feel not being able to serve faster than 135 today," she asked. "I just know you like to serve big, and it wasn't breaking 140 today."

Daniil Medvedev lost his cool Sunday night at the US Open, leading the crowd in a round of boos for a chair ump -- before he annihilated his racket in a wild post-match meltdown.

The tennis star's outburst began late in his tilt with Benjamin Bonzi at Louis Armstrong Stadium in New York ... after a photographer had left his spot and walked along the side of the court, delaying the action.

The match's official, Greg Allensworth, awarded Bonzi a first serve as a result of the cameraman's actions ... which enraged Medvedev.

Taylor Swift and Travis Kelce have a packed social calendar this weekend ... and, they're keeping the good times rolling, hitting the US Open for the men's final.

The happy couple arrived in Queens for the match just minutes ago ... rolling into the USTA Billie Jean King National Tennis Center hand-in-hand.

Check out the clip ... T-Swift's in a pretty standard pink dress, showing quite a bit of leg in the miniskirt. Travis is decked out in his country club best -- all white ensemble with red and green trim and a matching bucket hat.

Aryna Sabalenka's win at the US Open in New York on Tuesday night ended up being a big victory for all in attendance ... as she promised free booze to everyone who watched her score the W.

The 26-year-old made the offer just after rolling through Zheng Qinwen in the quarterfinals at Arthur Ashe Stadium ... when ESPN's Pam Shriver asked her how she planned on getting support in the next round against American Emma Navarro.

"Umm," the Belarusian said, "drinks on me tonight!?"

The U.S. Open teed off a week ago, but champ Bryson DeChambeau's living it up like he just sank the tourney-winning putt ... partying, trophy in hand, in downtown Nashville -- and it's awesome!

The 30-year-old champ was seen walking the streets of Tennessee's capital with the U.S. Open trophy ... as Bryson and his new hardware got in line to enter a bar on Broadway.

It is unclear if Bryson was meeting up with friends, family, or a mix of both ... but the group linked up outside Jason Aldean's Kitchen and Rooftop Bar -- which opened on the Broadway strip back in 2018.

The golf world is mourning the death of Ivor Robson -- better known as the "Voice of The Open" -- including Tiger Woods who thanked the icon for making each Open Championship "so memorable."

The Open released a statement on Tuesday announcing the death of Robson at 83.

Tiger paid tribute once the sad news broke, writing, "Thank you Ivor for making each one of my Open starts so memorable," Woods said on X.

Other golfers honored Robson, as well. Thomas Bjorn called him "a real legend in our world who will be deeply missed" and Paul McGinley described him as "the most famous & popular first tee starter golfer has ever had."

McGinley added ... "His legacy will be that iconic and quintessential British voice of his."

Robson began his career at The Open in 1975 ... and was one of the most admired announcers in sports until his retirement in 2015 after 41 Championships.

In fact, Robson, who established the famous "On the tee" introduction, was known to not even take bathroom breaks during the Championships.

Martin Slumbers, CEO of The R&A (Royal and Ancient Golf Club of St. Andrews), expressed sadness over Robson's passing.

"He was popular and well respected among all golfers who played in The Open and I know that they will share in our sadness at this news," Slumbers said.

"On behalf of all of us at The R&A, I would like to convey our heartfelt condolences to his wife of 61 years, Lesley, and the Robson family."

In 2015, when Ivor called his last Open Championship, he said ... "It has been a wonderful career. It's been a great honor," Robson said at his final announcement. The way I have been treated by players, officials, sponsors ... thank you all very much."
