Chinese teenager Ding Jun Hui has suffered a shock defeat in Prestatyn, denying the youngster a place in the final stages of the Welsh Open.
The 18-year-old beat Jimmy White, Paul Hunter and Steve Davis on his way to winning the UK Championship in York last month but failed to make it through to Newport after defeat to Ricky Walden.
Walden, the world number 48 from Bagillt in North Wales, compiled a highest break of 124 during his 5-3 victory which sets up a meeting with former world champion John Parrott next month.
Judd Trump from Bristol became the youngest player to qualify for the final stages of a ranking event when he beat Adrian Gunnell of Telford 5-1.
Trump, who turned 16 last August, was given a wildcard to play on the circuit after enjoying a successful junior career.
He completed victory over Gunnell with breaks of 84, 77 and 56, winning the sixth frame in only six minutes.
Rising Northern Irish star Mark Allen failed to make it to Newport after he was beaten 5-3 by Welshman Ryan Day, who appeared in the quarter-finals of his home event last year.
Allen, 19, led 3-1 but Day won the fifth frame on the black and grew stronger as the match wore on.
Tony Drago, who spent five seasons in the elite top 16 in the 1990s, faces relegation from the circuit after losing 5-3 to Glasgow’s Scott MacKenzie, who made consecutive centuries of 135 and 125.
Drago is currently 49th in the world rankings having won only one match all season and has only his home event, the Malta Cup which starts next week, remaining.
If he drops out of the top 64 at the end of the campaign he will fall off the main tour after 21 years as a professional.
