Judd Trump suffered a shock 13-9 loss to Jak Jones in the quarter-finals of the World Championship at the Crucible Theatre in Sheffield.

Having resumed at 8-8 overnight, world number two Trump once again struggled to find his rhythm in a tactical affair that worked in his opponent’s favour.

Breaks of 87 and 61 helped Jones pull clear at 11-9 and the Welshman sealed a famous victory with a superb run of 106.

Jones will now play seven-time champion Ronnie O’Sullivan or 2015 winner Stuart Bingham in the semi-finals.

The 30-year-old, nicknamed the Silent Assassin, is playing in the tournament for just the second time and is aiming to become only the third qualifier to win the world title after Terry Griffiths in 1979 and Shaun Murphy in 2005.
