Eight-time and defending champion Ronnie O’Sullivan crashed out on the opening day of the UK Championship after a 6-4 defeat to Barry Hawkins in York.
Hawkins reeled off four frames in a row to haul back a 4-2 deficit and clinch only his third win over O’Sullivan in 21 career attempts.
It was a remarkable revival by the 45-year-old, who compiled four consecutive half-centuries that left his illustrious opponent stuck in his seat for three straight frames.
“He looked strong and took his chances. I’m all right about it and I’m pretty much used to it. You just have to roll with it. It is what it is.”
O’Sullivan had started in style with two century breaks to establish a 3-1 interval lead, and looked all set to extend his dominant record over his rival, who had not beaten him since the 2016 World Championships.
But the top seed was unable to punish Hawkins for a missed pink to the middle in the next and a break of 57 proved enough for the Kent man to level the match at one each.
Hawkins missed two early chances in the next as he fell back behind, before O’Sullivan deposited his second century, a 114 which swept him into the interval with an ominous 3-1 advantage.
Instead, a display of petulance by O’Sullivan, when he smashed his fist onto the table after missing a red to the middle early in the seventh frame, proved the turning point.
A 73 clearance by Hawkins reduced the deficit again, and subsequent breaks of 75 and 88 without reply completed his dramatic turnaround and took him to the verge of victory.
“It’s been eight years since I beat him so it’s a massive win for me,” said Hawkins. “So many times I’ve been in this position against him and I’ve just crumbled, but I didn’t crumble today.
“I’m so proud of the way I stood up and took it the way I did. Hopefully it will give me more confidence. If I can’t take confidence from a win like that, I don’t know what’s wrong.”
Concluding a dramatic opening session of the Championship, Shaun Murphy edged a 6-5 win over former champion Zhao Xintong, who is on the comeback trail after a two-year ban for his indirect involvement in a match-fixing scandal.
Afterwards Murphy suggested that his recent coaching arrangement with the famously combative former world champion Peter Ebdon might have given him the edge to get over the line.
“Maybe in the last few years I’ve gone a bit soft,” said Murphy. “I think I’ve probably forgotten over the years that out there, in the pit, it’s gladiatorial.
“I’ve probably gone a bit genteel over the last couple of years, but no more. Working with Peter has changed that.”
In Saturday’s evening session at the Barbican Centre, David Gilbert held off a fightback from Xiao Guodong to win 6-4.
Gilbert had made runs of 53, 72 and 98 to open up a 4-2 lead only for Xiao to fight back with a couple of half-century breaks.
World number 22 Gilbert, though, closed out the match by taking the next two frames, finishing off with a break of 63 to set up a second-round match against Hawkins.
On the other table, Ding Junhui beat Robert Milkins 6-5, sealing victory with a break of 63 after registering a 135 break in frame 10 to force a decider.
