NEWPORT, Wales (AP) -- Christian Cevaer, surprise winner of the European Open on Sunday, withdrew from the Wales Open after 12 holes on Thursday because of exhaustion.
Cevaer said he felt dizzy on the course and withdrew on doctor's orders.
The 39-year-old Frenchman, who lives in Switzerland, said the elation of winning the European Open combined with problems with his managing agents "have caught up with me."
He had been unable to get home after his victory on Sunday. "I didn't sleep that much. The problems off the course are causing me a lot of stress and turmoil. They are taking a bit of sleep away."
He added that he also had physical problems stemming from the stress of worrying about the management company.
"The combination of all those factors meant I was unable to perform on the golf course today," he said.
He next plans to play in final qualifying at Sunningdale Open for next month's British Open at Turnberry.
