Ritchie Edhouse left the world champion Luke Little Lits with a dramatic last 16 finish from 12.
The British, 18-year-old citizen 6-5, Dutch Gian Van Veen and a quarter-final show to book the Mattioli Arena in Leicester to make a reservation with a tense result.
While Littleler tried to make 120 check-out to leave the upper finish of the world number 26, the double hit the double Five instead of the double top and was forced to advance the first dart.
The young man survived a 4-1 deficit to get ahead 5-4, but could not close the match.
At the last eight, Edouse will participate by Josh Rock of North Ireland, who defeated Danny Noppert 6-3, after reaching a end of nine darts in the third round of Matt Campbell, and will face the next Gary Anderson.
Elsewhere, he cope with Ian White Luke Woodhouse and plays Jonny Clayton Gerwyn Price.
