"I am crying more than I did when I won the Worlds," Smith said. "Playing Nathan [Aspinall] there, he was outscoring me.

"I wasn't playing well at all and then I hit that 136 and then the 132 and I just knew that would have hurt him.

"I was like. 'kick on now' and I wanted to do cartwheels, backflips, everything but because it was Nathan I had to keep it calm and collected and apologise to him.

"I do feel sorry for him because I want him there as well as me so that was really hard."

Smith, although feeling the effects of an emotional night, stayed resolute in the final to deny Humphries the chance of clinching a record fifth nightly win in the Premier League.

Despite Humphries reeling in the 'Big Fish', Smith took four legs in a row and a big 140 checkout for the 6-3 win, a big confidence booster heading into a big night at the O2.

"To get another win, it does feel really good," said Smith after the win.

"After that first week, I think I was on 10 points after three weeks.

"It wasn't until week 10 or 11 I made a final. It was one of those hard things.

"The last couple of weeks I really pushed through and now I am at the O2.

"I have never cried that much."
