Bryson DeChambeau hits glow-in-the-dark balls at Donald Trump's golf course in brilliant new video - after drinking wine out of the trophy with Eric following US Open win

Newly-crowned US Open champion Bryson DeChambeau celebrated his victory on Sunday night by hitting glow-in-the-dark golf balls at Donald Trump's course in Westchester.

The big-hitting American claimed the second US Open title of his career on a dramatic final day at Pinehurst, where he eventually held his nerve to prevail following an extraordinary collapse from Rory McIlroy.

While McIlroy stormed straight out and headed home after his late capitulation, DeChambeau celebrated his first major triumph in four years with Trump's family at his Westchester National Golf Club.

The former President, who could not be there himself, sent a video message to congratulate him on the night before things took a boozy turn, with Bryson soon drinking wine out of his US Open trophy alongside Trump's son Eric.

And later on in the evening, a brilliant video has emerged of him enjoying a late night driving session in the dark on one of the Westchester courses.

Eric's wife Lara Lea posted a clip of DeChambeau hitting glow-in-the-dark golf balls far into the distance as onlooking spectators let out huge cheers.

'SEND IT, Bryson,' Lara Lea wrote alongside the video.

As well as landing a second career major, DeChambeau also scooped a stunning $4.3million for his victory on Sunday - which will always be remembered for the manner of McIlroy's collapse on the closing holes.

The Northern Irishman bogeyed three of the last five, with two putts from a combined range of seven feet blowing up his two-shot lead and allowing his closest competitor to pip him to glory. 

Trump, who has close ties to LIV and has been seen at a handful of their events in recent years, posted a congratulatory message to fellow American DeChambeau on Truth Social on Sunday night and even appeared to dig out McIlroy.

He spoke of 'toughness and inner strength', as well as praising LIV golf - which McIlroy has been a fierce critic of in the past.

The 78-year-old wrote: 'Congratulations to Bryson DeChambeau on his incredible WIN of the United States Open! 

'He showed a toughness and inner strength, matched perfectly with his GREAT Golfing Talent, that can never be denied! Under massive pressure, he pulled off some of the greatest shots ever made, especially his spectacular sand save on the 18th Hole that gave him the Victory.

'"Mr. 58" has always been a WINNER, and will go on to many more Major Championships. He is a truly tough competitor, even a nasty one, but he also happens to be a great guy. The U.S.A. could not be better represented.

'Congratulations also to LIV Golf for their genius in signing Bryson and other of the best Golfers in the World. 

'Hopefully Golf will soon come together as one, fully united, which is the way it should be!'
