A relieved Stephen Maguire withstood a barrage from Belgian prodigy Luca Brecel to reach the third round of the UK Championship.
Former world No 2 Maguire trailed 4-1 and 5-2 against 18-year-old Brecel at York's Barbican Centre before staging a comeback.
Having made 99 in frame six, the Scot won the last four frames to prevail 6-5 with the help of 68, 50 and a closing 91.
"I didn't fancy that at all at 5-2, didn't fancy spinning off four," Maguire said. "I'm just very relieved.
"Even in the last frame it could have gone either way, he got in and hit the balls nice.
"I pushed the boat out in the end, went for a cross double and it paid off."
World No 4 Judd Trump had things all his own way during a 6-0 win against Dechawat Poomjaeng.
Trump outscored his Thai opponent 497-114 overall and was on course for a 147 in the third frame before missing the 13th black.
Trump said: "It was a bit too easy, I wanted to be pushed a little bit more. Apart from the 147 attempt, it was too easy."
Asked at what point he felt the maximum bid was on, he said. "Before the frame started. Every frame, I'm going for a 147, I've not done one on TV so that's my main aim.
"It was a good attempt. I had a kick and then got back into position and I just took my eye off the black."
John Higgins also had a comfortable time, the three-time former champion beating Rod Lawler 6-1, while Scott Donaldson produced a notable upset to beat Mark Davis 6-5.
Anthony McGill crushed Chris Norbury 6-0, finishing with a 103, to add to a day of Scottish success.
Ricky Walden also went through to the third round with a 6-2 win over Leeds' Peter Lines.
Walden, the world No 12 from Chester, led 4-1 after breaks of 54, 66 and 79. Lines pulled one back and had a chance in frame seven, but Walden won it and finished the match with a 76.
Matthew Stevens needed a contender for shot of the tournament to put his second-round match against Yu Delu to bed.
The Chinese player came from 2-0 down to level at the interval and the players alternated frames to 5-5.
The decider lasted over 40 minutes, with a good exchange of snookers on the colours. Yu sank the blue but could not get on the pink and Stevens then stroked a superb long pot into the yellow pocket to win the game.
"It was about time I potted a long ball," he said. "It was a poor game. Yu probably played better than me and how I won playing like that, I don't know. But I'm in so I can improve."
Also on Sunday, Ding Junhui overcame his boyhood hero James Wattana 6-1, Mark Allen beat Dave Harold 6-3 and Mark Williams stepped up a gear after his mid-session interval against Rory McLeod to triumph 6-3.
