World number 16 Anthony McGill got defending champion Ronnie O’Sullivan and left the World Cup game of the second round after an exciting first session 4-4.
Six-time winner O’Sullivan showed his majestic personal best when he took a 3-1 lead in breaks 81, 105 and 138.
O’Sullivan, 45, then took a 4-1 lead and missed a big chance to make it 5-1.
But the Scot McGill responded, holding his nerve in an increasingly tense game to win three frames in a row.
The 30-year-old’s comeback should have been even sweeter. The two-time ranking event winner, a Crucible semi-finalist last year, was in the best position to score a 147 in frame 7 but left the black painfully sitting on the 97.
It would have been only the 12th maximum in Crucible’s history and would have earned him £ 40,000 plus at least a portion of the tournament highscore prize of £ 15,000.
The best-of-25 frame match continues on Friday morning and ends on Friday.
Shaun Murphy struggled 5-3 down to secure his place in the final 16 with a 10-7 win over Mark Davis.
Davis, 48, made his 12th appearance at the snooker showpiece event, surpassing the 2005 underdog in the opening session.
But Murphy, who was lifted by a century in the last frame, narrowed the gap to 5-4 and improved significantly on resumption.
Breaks 56 and 92 and helped him win four of the next five frames for an 8-6 lead, and after dividing the next two, world number seven crossed the finish line with a staggering 131.
“There’s a massive difference between 6-3 and 5-4. I’ve been released from prison,” said Murphy, who will face reigning Masters champion Yan Bingtao from China in round two.
“Mark always plays the right shot and he’s so hard to beat. I knew I needed a quick start today. It’s a big win and I’m thrilled how I finished it.”
Leicester’s Mark Selby scored two centuries and took six more breaks of more than 50 in the first session of his first round match
