World number one Mark Williams added to his dismal PTC record, going down 4-1 to the commanding Passakorn Suwannawat in round four.
Williams has collected just £400 in PTC prize money, and will need to turn it around if he is to qualify for the Players Championship finals.
Shaun Murphy lost his first game to 20 year-old Welshman Michael White, with the youngster taking the deciding frame.
White then secured his place in the last 16 with a 4-1 thrashing of Martin Gould.
Legend Steve Davis fell one game short of a place in the last 16, losing 4-2 to Yu De Lu after a fine run during the day.
Elsewhere 2010 world champion Neil Robertson showed his class to reach the final day, recording wins over Chris Norbury, David Hogan and veteran Peter Lines.
The final day of action on Sunday features 147 hero Ronnie O'Sullivan, Mark Selby and dark horse Passakorn Suwannawat, with last 16 matches through to the final being played.
