Snooker results: Thepchaiya Un-Nooh beats Judd Trump in deciding frame to reach Scottish Open semi-finals

A match full of quality and featuring a number of big breaks turned into a dogfight in the deciding frame, both players wilting under the pressure until Trump missed a tough pot to the yellow pocket and handed victory to his clearly relieved opponent.

When Trump edged into a 4-3 lead, he would have surely felt he had one foot in what would have been only his second semi-final of the season, but Thepchaiya ensured the match went the distance thanks a typically rapid brake of 104 moments later, and he gave himself numerous chances of winning the decider.

A poor positional shot on the final red meant Thepchaiya was made to wait for his victory, and when Trump missed the final pink with the rest, Thepchaiya was left with a tricky rest shot of his own on the black.

Again Thepchaiya fluffed his lines, leaving the black hanging over the pocket and allowing Trump to force a re-spotted black, meaning this latest edition of snooker theatre had one final act to deliver.

This time is was Trump who had the first bite of the cherry after Thepchaiya produced a poor safety, but he missed from distance and watched on in horror as the black trundled down the table and settled close to the bottom corner pocket.

A puff of the cheeks from Thepchaiya upon finally finishing the job told the story of a thrilling afternoon, and he can now look forward to a semi-final with Gary Wilson.

The action started at a ferocious pace as Trump rattled off centuries in frames two and four, but Thepchaiya claimed a share of the early spoils to ensure the scores were level at the mid-session interval.

Trump then appeared to be taking control when taking two of the next three frames, but Thepchaiya winning the sixth frame despite Trump firing in a break of 61 kept the former in the hunt, and his dazzling century soon after – the third of the match – set up a memorable finish.

"I am still excited. I have one thing to say: everything has a first time. I’ve never beaten Judd before. I believe in myself and I can do it. I beat him today and I’m so happy," Thepchaiya told World Snooker Tour.

"I lost to him 10-9 at the Crucible. I have never forgotten that match. He won the world trophy as well. I am so happy to beat him today.

"I had to be positive on the first black I missed with the rest. I thought I would pot it, but my cue speed wasn’t fast enough, it was too slow.

"I was so happy to get over the line. The table is fast, I thought the black Judd missed wouldn’t roll far enough for me, but it did."

Gary Wilson awaits for Thepchaiya after he won four frames on the bounce to beat Kyren Wilson 5-3.

A run of 50 and two further breaks of 73 had given Kyren Wilson the early advantage, but the match turned scrappy thereafter and it was the Tyneside potter who finished the stronger.

Gary Wilson signed off with a break of 74 to confirm his best performance of the season to date, but there were a few words exchanged between the pair afterwards as Kyren Wilson complained about his opponent's apparent bad behaviour both in the match and the mid-session interval.

Gary Wilson said afterwards: "To be honest he was quite serious. He was saying he thought my attitude was terrible when I left a red over the pocket. I had a joke with the crowd and it wasn’t against him.

"He said he could hear me banging about at the interval and it wasn’t the way to go on. I said that I was sorry if it affected him. I didn’t mean it like that and I’m allowed to release a bit of steam in the interval.

"Emotions get the better of us all at times. I certainly didn’t mean anything towards him about it."

Robertson marches on

Neil Robertson maintained his recent stranglehold over Mark Selby, running out a comfortable 5-2 winner of their quarter-final clash.

Robertson has now won each of his last seven meetings with Selby and produced another masterclass to confirm his position as firm tournament favourite.

For Selby's part, he won his two frames with fine century breaks, but was once again outmuscled by the Australian who was typically deadly from distance and devastating in the balls.

Robertson raced out of the traps and breaks of 133, 99 and 83 put him 3-0 in front before Selby had even managed 10 points of his own, and it was to his credit that he then won frame four with a terrific 104.

Robertson offered no respite, however, reeling off a ton of his own in reply, before Selby offered the same riposte in the very next frame – three centuries in succession illustrating the quality of play both players were producing.

But it was Robertson who had the stronger hand and he closed out the match with a break of 60 to set up a last-four meeting with Joe O'Connor, who reached only his second ranking semi-final courtesy of a 5-1 victory over Ricky Walden.
