较早前奥沙利文4-1淘汰了迈克尔·霍尔特，来到小组决赛对决马克艾伦，直到3-5艾伦拿到赛点时，一切都中规中矩，按部就班，但眼看艾伦胜利在望时出现状况，火箭上场击打一颗红球未果，他认为艾伦起身给球杆擦巧克粉，妨碍了自己专注打球的视线，还跑到艾伦面前与之理论，艾伦表示自己并没有做错什么。在裁判马塞尔.埃卡德的调停下，比赛才得以继续进行。僵持时间大约有一分钟。之后艾伦上场66分一杆清台，拿下比赛。
至此，2020年冠中冠的四名半决赛名额已全部出炉：罗伯逊、特鲁姆普，塞尔比和马克-艾伦。他们的打法各具特色，但有一个共同之处，都是八零后。
The Antrim man was on top form in the Group 3 final, but the match will be remembered for a clash between the two players in the last frame. O’Sullivan, down on a red, pulled up and asked his opponent to keep still. Allen denied any wrongdoing and a discussion ensued before referee Marcel Eckardt asked O’Sullivan to play on.
O’Sullivan, who trailed 5-3 at the time, wasn’t able to make it a frame-winning visit, and Allen, who had pulled ahead from 2-2 at the mid-session, made a clearance of 66 to advance to the semi-finals, where he’ll meet Judd Trump on Saturday evening.
Allen came through a deciding frame against Scott Donaldson in his group semi-final. Neither play was at their best but the World No.8 pulled it together in the final frame to make a 125 to set up the Group Final against O’Sullivan.
