Mark Williams came from 4-1 behind to beat Matthew Stevens 6-4 and reach the quarter-finals of the Masters in London on Wednesday.
The former world champion struggled in the opening frames and was on the verge of going down 5-1 against his fellow Welshman.
But Stevens missed a routine brown that would have put him four frames in front and made several more errors as Williams won five frames in a row.
“I didn’t play very well at all to be honest, neither did Matthew,” Williams told the BBC.
“He missed a sitter of a brown for 5-1 and I don’t think I’d have come back from 5-1 to be honest.
“Even though I wasn’t playing too well I was still trying 100 percent, and perhaps that’s what got me through in the end.
“It’s easy to win when you are playing well, but it’s hard when you’re not playing too well and I was getting hammered out there really. I’m over the moon that I just stuck in there, tried my best and managed to turn it around somehow.
“Matthew helped me out a lot, he missed a lot of balls he normally wouldn’t miss. Perhaps I dragged him down a bit and pounced on him.
“Coming into this tournament I practised really hard and was probably playing the best I have for years and years, knocking 147s in every single day near enough.
“I was quite confident coming up here and then I go out there I can’t make 47. If I can bring the practice to the match table I’ve got a chance, but I just can’t do it at the minute. I might be trying too hard.”
