Paris - Five-time world darts champion Raymond Van Barneveld quit the sport on Thursday, admitting his slumping form had left him feeling "ashamed".
The 51-year-old Dutchman announced his immediate retirement after a 7-1 loss to compatriot and world number one Michael van Gerwen - 22 years his junior - in the Premier League in Rotterdam.
"I played really bad, I lost 7-1 so today I knew I was in relegation and I felt ashamed," Van Barneveld told Sky Sports.
"Five-time world champion and I was thinking 'Do I deserve this? I don't think so' but it is reality. I'm not good enough.
"For me I've made a decision I am done now. I don't want the pain any more. It's pain every single week for the last three or four years.
"I'm OK with this decision. I'm relieved. I'm done."
