Preview: Day-5 World Championship Qualifying
Former world champion Peter Ebdon defeated Jack Lisowski to win 10-9 and move one victory away from a return to the Crucible in Sheffield.
In a high-scoring affair, Ebdon looked certain of a place in the final qualifying round at Ponds Forge when he opened up a 9-5 advantage, only for his opponent to fight back with four frames on the spin to force a decider.
The 2002 champion held his nerve, though, compiling a 69 in the last to see off his fellow Englishman- Jack Lisowaski.
Ebdon will meet Michael Holt on Judgement Day as Michael Holt beat Eden Sharav with a 10-4 scoreline.
Elsewhere, Day five conjured up a few big upsets as the likes of Joe Perry and Mark Davis were sent packing.
Perry fought back from 9-6 down to force a final frame shoot-out with Akani Songsermsawad. But lost to Akani Songsermsawad 10-9.
Songsermsawad, 21, wasn't the only young international player to advance, perhaps signalling an imminent change in the guard of the sport.
The talented teenager from China, Yan Bingtao beat Mark Davis by 10-7.
Alexander Ursenbacher edged out Scott Donaldson by 10-9.
Yan Bingtao will play amateur Alexander Ursenbacher for a Crucible berth.
Yan and Ursenbacher's clash will guarantee that there'll be at least one debutant in the 2017 edition of the World Championship.
Meanwhile, Yan's countryman Zhou Yuelong won the last three frames as he beat Ian Preece for a 10-8 success.
Most of the encounters went near the full distance as the drama and pressure went up a notch with a place in Thursday's last 32 draw coming into view.
Former quarter-finalist Jamie Jones beat Alfie Burden 10-8 while Martin Gould and David Gilbert beat John Astley 10-6 and Rhys Clark 10-6 respectively .
Hammad Miah won by 10-7 against Martin O'Donnell. Whereas Yu Delu gained victory over Robbie Williams by 10-7.
Earlier on Sunday, several other ties reached the halfway stage of their clashes at the penultimate stage.
11-time world women's champion Reanne Evans struggled to follow up her headline-making first round victory over Robin Hull as she trails Lee Walker 6-1 overnight.
Michael White, Mark King, Dominic Dale, and Xiao Guodong are among the others to boast healthy cushions going into their concluding session on Monday.
