Judd Trump's hopes of becoming just the fifth player ever to hold all three Triple Crown titles were ended in a shock defeat to Nigel Bond at the UK Championship.
World No 1 Trump was odds on to beat veteran Bond and maintain his quest to win the title at York Barbican.
But the 54-year-old outsider, ranked 98 in the world, rolled back the years to produce a stunning 6-3 victory.
Bond, who turned professional 30 years ago and was World Championship runner-up in 1995, opened up a 5-3 lead, and then kept his cool in frame nine after a long duel on the final pink, before potting it and ending Trump's title hopes.
"He's the man of the moment. I'm 54. What am I doing?" Bond told BBC Sport. "Once I settled, I played some good stuff out there. It's unbelievable.
"Judd missed one or two, which helped, but I was just trying to show people I can still play. When I am feeling good, my game is still there."
Trump, meanwhile, added: "Anything can happen in snooker. He used his experiences, and he scored heavily as well.
"I didn't do a lot wrong. It wasn't like I was getting in and missing.
"The pace of the game was very slow and hard for me to get a rhythm. Everyone's human. You can never get too excited or too down."
Former world champion Neil Robertson was given a fright by Mark King before booking his place in round four.
The dogged King levelled the match from 2-0 down and stayed on Robertson's heels before he lost a tight tenth frame and the match 6-4.
But 2015 world champion Stuart Bingham cruised into the last-16 with a 6-1 victory over China's Zhao Xintong.
Northern Ireland's Mark Allen, former world champion John Higgins and Welshman Matthew Stevens all made it through with comfortable wins in the evening session.
