Kyren Wilson won one of the most outlandish final-frame deciders that snooker fans have ever seen to secure his place in the final of the World Championship at the Crucible in Sheffield. 

A visibly shaken Wilson prevailed 17-16 against Anthony McGill in an astonishing finale which included McGill missing a snooker eight times in succession and effectively concluded when Wilson fluked a green over three cushions.

The frame score finished 103-83 in favour of Wilson, who struggled to contain his emotions upon fluking the green, and subsequently broke down in a BBC post-match interview.

Wilson had returned for their concluding session with a 13-11 advantage and stretched his lead to three frames with a nerveless break of 94.

But qualifier McGill stormed back with consecutive breaks of 84, 87 and 122 to achieve parity at the mid-session interval.

Wilson nudged back in front with a break of 82, but McGill appeared unfazed and pulled back level before a nerveless 98 sent him one frame from victory.

Wilson forced the decider after a rerack, but neither player could possibly have envisaged the drama that was soon to unfold.

Both players missed simple chances to claim frame and match, with McGill running aground on 39 then Wilson missing a simple red to middle on 47.

With the black teetering over the top pocket, Wilson snookered McGill on a nearby red and the Scot missed it eight times in a row, leaving him requiring snookers.

Yet Wilson duly stepped up and screwed the white back into the middle pocket, with another subsequent in-off handing his opponent back the initiative.

The red then became perched tight on the top lip of the middle pocket, with both players trying and failing to pot it via the bottom cushion.

McGill managed it at the second attempt, but with the colours seemingly at his mercy, he snookered himself on the green, which Wilson subsequently missed to effectively take the match.

After an extended safety battle, Wilson fluked the green via three cushions, leaving McGill requiring snookers again and Wilson ultimately thanking his outrageous fortune.

 "I feel like I've had something stolen from me – not by Kyren, but by the snooker gods," McGill lamented afterwards. 

Wilson was similarly perplexed by what transpired.

"I couldn't believe what was happening," he admitted. "It was absolutely mental. It was one of the best semi-finals you’ll ever see, but I wish it hadn’t ended the way it did."

The English cueman now faces the difficult task of composing himself for his final debut on Saturday, but insisted he will be doing everything he can to resist a repeat performance.

He added: "You can’t just rely on luck to get you a world crown and, whoever I play in the final, I’ve got to produce great snooker and I’m not going to get there by fluking balls.

"I can go out and enjoy the occasion and give it my all. I’m going in there to win the world title, but to have the pressure on the other guy hopefully plays in my favour."
