John Parrott has been beaten 5-4 by Andy Hicks in the first round of the British Open in Brighton.
Parrott suffered disappointment again
The former world champion is struggling to retain his place in the top 32 of the world rankings for next season.
Parrot looked certain to progress when he recovered from dropping the first frame to power three up with four to play against Hicks.
But he could not apply the finishing touch and Hicks stormed to win with a 126 break in the deciding frame.
Hicks was delighted with his comeback. He said: "It was a great way to finish things off.
"I've lost a lot of 5-4s over the last few years, so this is a good feeling. I dug deep, got a chance in the last frame and took it.
"I suppose determination pulled me through in the end."
Welshman Dominic Dale also improved his miserable recent run of results with a
5-2 victory over Northern Ireland's Patrick Wallace.
Dale's reward for bringing down the curtain on a six-match losing sequence - the last two of which were 5-0 whitewashes - is a second-round encounter with Stephen Hendry.
Shaun Murphy, an LG Cup quarter-finalist last month, beat Dave Harold 5-1.
He moves forward to tackle title-holder Paul Hunter.
