Mark Selby has completed a memorable comeback against Stephen Maguire to secure his place in the semi-finals of the Saga Insurance Masters.
Last season's 888.com World Championship finalist battled back from 5-3 down to triumph 6-5 at this year's £460,000 showcase tournament at the Wembley Conference Centre.
And with his dramatic final frame victory will play either one of two former world champions, Shaun Murphy or Ireland's Ken Doherty in the next phase on Saturday.
"I'm gobsmacked to still be in the tournament," said Selby, who clinched victory with a pressure break of 54 in the 11th and final frame. "It was a massive occasion for me - and I felt it. Overall, apart from the last three frames, Stephen was probably the better player.
"But luckily I was able to stamp my authority on the game and didn't give him much of a chance in the last three frames.
"Funnily I felt more relaxed when I was 5-3 down, so I'm looking forward to the semi-finals. Maybe I'll go 5-3 behind and then see what happens.
"I was close to going out of the tournament. I'm a bit fortunate to still be in the tournament, but if I am destined to win it they'd I'd be chuffed to bits.
"I wouldn't mind winning the tournament the way I'm playing now.
"It's never over until they've potted that last ball. I just kept feeding myself positives because I am until he pots that final ball."
Selby pocketed a break of 58 to win the opening frame, but world number 10 Maguire won the next three frames to deservedly lead at the interval.
The first frame after the break went Selby's way, but this season's Northern Ireland Trophy champion and UK Championship finalist Maguire earned himself a two-frame cushion with an excellent break of 67 to edge 4-2 ahead.
It could have quite easily gone 5-2 in the Scot's favour, but having failed to add to a composed break of 59, Selby struck to take the frame just when it looked as though it had slipped through his grasp. A break of 30 did the trick, the 24-year-old Midlands cueman winning the frame on the final black.
Selby should have levelled at 4-4 but missed a simple yellow ball to square matters as Maguire went 5-3 ahead.
However, the Masters debutant rallied and with breaks of 103 and 54 completed a superb fightback.
"Usually when you miss a ball like that you get punished, but I just can't believe I've got beat," said Maguire. "I was thinking I was in the next round, but he stepped up a gear and played great.
"Even when it went 5-4 I thought if I got my chance I'd finish it. I find it hard to take, 5-3 up was the right scoreline, but he missed a bad yellow to make it 4-4.
"He was out of the tournament bar one ball, but all of a sudden he had an extra lifeline and he took it."
