Producing the same level of sustained heavy scoring which enabled him to thrash Johnston-Allen 9-3 in the final of this year's European Open, White was at the table for only 62 minutes.
White said: 'I concentrated well and I am obviously delighted with the way I played. I still feel a bit rusty after neglecting my snooker over the summer and I need a few matches to put that right.'
Tomorrow White meets the winner of today's fifth-round match between Neal Foulds and Steve James, the world No 10.
Mark Bennett set up an all- Welsh quarter-final meeting with Terry Griffiths by beating another fellow countryman, Swansea's Tony Chappel, 5-1. Alan McManus, who thrashed the former world champion, Cliff Thorburn, 5-1, will now play Nigel Bond or John Higgins in the last eight.Reuse content
