Wu Yize and Mark Allen's World Snooker Championship semi-final is locked at 7-7 after an extraordinary 14th frame lasting 100 minutes and 21 seconds, the longest in Crucible history. Allen trailed 6-2 overnight but won five consecutive frames to lead 7-6 before the marathon frame.
The frame saw eight reds clustered around the black ball near a corner pocket, leading to a 55-minute period without a pot. Allen, leading 47-13, refused a re-rack. Referee Marcel Eckardt, prompted by tournament director Rob Spencer, warned players they had three shots to resolve the situation or face a re-rack. Allen eventually fouled by knocking the black into a pocket, allowing Wu to win 88-66 after a lengthy safety battle.
Steve Davis called the frame 'an embarrassment to snooker', while Stephen Hendry said the referee should have intervened earlier. Kyren Wilson agreed, praising Allen's determination. Allen earlier made a tournament-best 145 break and his ninth century of the event.
In the other semi-final, John Higgins leads Shaun Murphy 13-11 after a tight session. Murphy hit a 105 break to become the fifth player to reach 100 Crucible centuries. Higgins responded with a 101 break to take a slender overnight lead.
