World number 40 Steve Farmer claims that fear of playing on the big stage is holding him back from progressing to a world title.
Telford-based Farmer was defeated 4-0 by James Wade in the third round of the PDC World Championships at Alexandra Palace on Thursday.
"I'm fighting a battle before I get up there," he told BBC Radio Shropshire.
"When I retire I might come clean on what it is. Just the thought of getting up there is terrifying."
Farmer beat Ronnie Baxter and Germany's Kevin Münch to book his tie against world number three Wade.
"I just can't play proper darts up there on that stage, it's really frustrating. I wanted to give James a really tough game and I didn't, I made it quite easy for him," Farmer added.
"I'm never going to give up darts, it's the best game in the world."
