Mark Roe has called on golf's governing bodies to change the rules after his disqualification from the Open.
Roe suffered disappointment at Sandwich
Roe was joint fourth at Sandwich after a brilliant third-round 67, but was disqualified along with playing partner Jesper Parnevik after the pair accidentally signed each other's cards.
The 40-year-old has called for rule changes, claiming a "clerical error" should not have denied him the chance to compete in today's final round.
"I went through the events in my mind when I was driving home on Saturday night and the only thing I remember was checking my total four times and then handing it to the gentleman," he said.
"I remember him saying clearly 'congratulations Mr Roe, great score'. I do remember, very clearly, 'nice score, two signatures, well played'.
"I think maybe it's time for a change of certain rules. There are rules that rightly penalise and rules that we all know are just blatantly unfair.
"I don't feel I made a mistake on Saturday - it was a clerical error, it was nothing to do with the game of golf, it was a piece of paper. My score was 67."
Roe admitted that he did not get a lot of sleep on Saturday night after he returned home.
"I got a bottle of champagne and drank myself to sleep," he confessed.
"I feel numb. It could have been one of the great days of my life and I've lost that opportunity.
But Roe refused to blame the officials who accepted his card, even though he would have had the opportunity to correct the error had the problem been spotted in time.
"In all honesty, I can't apportion blame to the people in the hut. I felt responsible for my scorecard. I've played the game of golf for long enough as a professional and this mistake has never happened before.
"I've abided by the rules for my whole career. I accept the blame but I would have liked the opportunity to have tested myself in the greatest arena."
