Welsh qualifier Michael White thrashed Dechawat Poomjaeng 13-3 to reach the quarter-finals of the World Championship in Sheffield.
The 21-year-old from Neath resumed 7-1 ahead and wrapped up the six frames he needed to win with a session to spare.
White, ranked 41 in the world, will play Ricky Walden or Robert Milkins in the last eight starting on Tuesday.
Victory there would see him become the first debutant to reach the semi-finals since Andy Hicks in 1995.
Judd Trump showed signs of the form that took him to the Crucible final in 2011 as he opened up a 6-2 lead in his second-round match with Marco Fu.
The Hong Kong cueman took the opening two frames but a break of 109 got the world number three up and running.
Trump levelled at 2-2 at the interval and reeled off four more consecutive frames on the resumption including two more centuries - 127 and 112 - to establish a commanding lead.
Shaun Murphy beat Graeme Dott 13-11 to reach the quarter-finals of the World Championship at the Crucible.
With the game level at 10-10, Murphy gained a crucial lead on a re-spotted black before closing out the match.
World number one Mark Selby will resume on Saturday afternoon with a 9-7 lead over Barry Hawkins.
Selby hit breaks of 98 and 103 to help him to a 5-3 lead after the morning session.
Hawkins, ranked 14, pulled level at 6-6 before losing the next three frames. However, he hit a break of 59 to win the evening's final frame.
