Judd Trump gained revenge over Thepchaiya Un-Nooh to move into the quarter-finals of the English Open in Brentwood.Trump, who lost 5-4 to the Thai player in the quarter-finals of the Scottish Open earlier this month, risked being forced into another final-frame decider.But the 2020 winner got the better of a lengthy safety battle in the sixth frame before reeling off a break of 47 to seal a 4-2 win and earn his place in the last eight.Trump told Eurosport: "I was constantly under pressure from the get-go.
The first frame was very important and I managed to steal that one and get into the game."I just had to keep battling. I didn't play my best but it’s always tough to play your best against Thepchaiya, you’re on edge and you’ve just got to get the job done."Earlier Ronnie O’Sullivan’s search for a first ranking title of the season continued as he crashed out 4-1 to world number 43 Martin Gould at the second round stage.But Gould’s good fortune did not continue as he returned in the evening session to lose his last-16 clash by the same score to Ashley Hugill, a result that sent the York player into the quarter-finals of a ranking event for the first time.Mark Williams opened with a break of 130 as he reached the last eight with a 4-2 win over Barry Hawkins, while Neil Robertson beat Ryan Day by the same score.
