Ali Carter pulled off one of one of the biggest wins of his career when knocking out Ronnie O'Sullivan at the Crucible Theatre.
On an afternoon of high tension, emotion and a few frayed tempers, Carter held his nerve under the most extreme pressure to progress to the quarter-finals.
Having trailed 7-9 overnight, the inevitable O'Sullivan comeback began when he took frame seventeen with a masterful clearance of 66 but Carter doused the flames by taking the next two before a flashpoint in frame nineteen.
Needing a snooker, O'Sullivan enjoyed a handy piece of luck when leaving Carter in trouble before a clear brushing of shoulders between the two player as they passed each other.
A few words were then exchanged and O'Sullivan responded by winning the last frame before the mid-session interval.
O'Sullivan looked ready to pull another back when well set on 54 but a simple blue into the middle was missed and his fate all but sealed, Carter showing nerves of steel to clear the table.
The great O'Sullivan escape failed to materialise as Carter always had the upper hand in frame twenty-two and went on to record a historic victory.
The two players shared a gracious handshake afterwards before Carter enjoyed an emotional celebration.
An emotional Carter told the BBC afterwards: "I'm just delighted to win, to get through.
"He's [Ronnie] such as amazing snooker player but he wasn't having it all his own way, I stuck to my task and today was my day.
"He was always going to go on a little spurt, he's always going to reel off frames but I just stuck in there."
On the shoulder brush, Carter added: "It was nothing really, I was walking to the table and he was walking to his chair.
"There was a lot of tension out there.
"It means a lot, it's a big tournament, but I'm only in the quarter-finals and I'm here to do a job.
"I want a world title on my CV."
O'Sullivan was gracious in defeat, telling the BBC: "I just wasn't good enough.
"He was first to every punch, he did a Mayweather on me.
"Ali's a tough competitor, he's always had that in him and that's why he's won so many tournaments and has been around so long.
"Ali was strong out there and he deserved his victory."
On the exchange, he added: "Sometimes it gets a bit tense out there but it was all a bit of fun and it's behind us now.
"Good luck to Ali for the rest of the tournament."
Hawkins makes his experience count
Having lead 9-7 overnight, Hawkins found himself under early pressure as Haotian claimed the opening two frames of the deciding session with breaks of 91 and 100.
Hawkins again got his head in front to lead 10-9 but once more, Hoatian levelled the scores by potting pink and black after Hawkins had gone in off when escaping a snooker.
The mid-session interval was to prove crucial, however, with Hawkins drawing on all of his previous experience after the resumption and producing runs of 54, 132 and 76 to take the final three frames and book his spot in the quarter-finals.
Wilson makes it through
Kyren Wilson will face Mark Allen in the Betfred World Championship quarter-finals after seeing off Welshman Jamie Jones.
World number nine Wilson won the first two frames of the evening session on Saturday to complete a 13-5 win.
Wilson will now face Northern Irishman Allen in a repeat of this year's Masters final.
Higgins leaves Lisowski on the brink
Jack Lisowski endured a horror show in his last 16-match with John Higgins.
The four-times world champion was at his ruthless best as he won every frame of the opening session, a break of 101 the highlight of his afternoon's work, and he holds a 8-0 lead heading into the second session.
Williams has the advantage
Mark Williams holds a 5-3 advantage against Robert Milkins after the opening session of their last-16 clash.
