Snooker Masters field was Mark Allen’s dream, and it’s currently happening.

Asked what had been the deciding factor, Allen told the BBC: “The safety (department) in the end. We both missed balls.

“I felt like as the match went on he was getting more edgy but I wasn’t playing well enough to capitalise, so it was just a matter of staying patient and taking my chances when they came.

“It wasn’t pretty, I’m sure it wasn’t pretty to watch but I couldn’t care less. I’m in the semis.

“I don’t mean this to sound bad to Jak, but that was like a three or four out of 10 performance. That really wasn’t good. But mentally I was like a 12 out of 10 and ready for anything.

“Sometimes that’s more important and that’s a match I would have lost a few years ago.”

With the contest finely poised at 8-8, Jones won the opening frame on Wednesday with a break of 77 before contributions of 66 and 64 from Allen edged him back in front as Jones missed a number of simple pots.

To his credit, the Welshman composed himself quickly to draw level with a break of 124 which was a total clearance in every sense as he deliberately potted the white along with the final black.

However, Allen took the next frame after twice trapping his opponent in costly snookers and a break of 64 then moved the left-hander to within one of victory at 12-10.
