Mark Allen's hopes of snatching the 2018 World Championship are over.
The Antrim man was beaten 13-6 by Kyren Wilson in the quarter-final as the English opponent successfully avenged his defeat to Allen in this season's Dafabet Masters final.
The pair had been locked at 4-4 after the first session on Tuesday morning but a crushing second session, in which Allen lost seven of the eight frames played, proved his eventual downfall.
With heavy favourites Mark Selby and Ronnie O'Sullivan both crashing out early and Ding Junhui following them this morning, the draw is fast opening up in Sheffield. Having already won the Masters this season, Allen would have fancied his chances of adding a maiden world title to his collection with his main rivals already eliminated.
However, his hopes are over along with those of Ding Junhui, who was beaten 13-5 by Barry Hawkins.
Allen won the final session's opening frame, looking more focused and composed, but when he missed a straight-forward blue in the next, Wilson mopped up and finished the match with a break of 53.
Wilson will now face either John Higgins or Judd Trump for a place in the final.
