Irishman David Morris has stunned world champion Mark Selby, beating him 6-4 in the second round of the Coral UK Championship in York.
Kilkenny native Morris clinched the biggest scalp of his career in style with a match-clinching break of 79 in the 10th frame, having earlier fired in a match-best 126 to nudge closer to the winning line.
World number 62 Morris turned 26 on Thursday, and he now heads into the third round where David Gilbert awaits him at the Barbican Centre.
Selby had reached the final in each of the last two years, winning the 2012 title before finishing runner-up to Neil Robertson 12 months ago.
China's Ding Junhui avoided going the same way as the Leicester potter, fending off crowd favourite Jimmy White in winning 6-2.
Giant-killer Morris was relieved to fend off Selby after admitting he became jittery once in front.
He said: "I was nervous all the way through the match. Even when I was 3-1 ahead I was still shaking a little bit on shots. I am not so used to the big stage but I just wanted to do my best every time.
"I made a 126 break to go 4-3 ahead. If he had won that frame, he could have ran out to 6-3. I am delighted to win and to beat someone of Mark's class is a big feather in my cap."
As world number one Selby prepared to head for home, Morris was able to consider the scale of his achievement.

"I had a few good wins last year but I don't think that compares to this because it is such a big event," he said, according to the York Press.
"I have had wins over Judd (Trump), John Higgins and a couple of others but this was in the UK Championship, in front of a packed audience and on the television table.
"That's a big thing to me. To beat the world champion you get a lot more recognition but there are so many good players now.
"To get a big scalp like that will give me confidence for the future."
