(CNN) -- Potential Ryder Cup vice-captain Thomas Bjorn is among four players tied for the lead after the opening round of the Wales Open at Celtic Manor -- the venue for next year's clash between Europe and the United States.
Veteran Dane Thomas Bjorn is among a group of four players who lead the Wales Open on Thursday.
Bjorn opened with a five-under-par 66 to share the lead with England's Nick Dougherty, Scot Alan McLean and 49-year-old South African David Frost.
"If I don't make the Ryder Cup team I am happy to help captain Colin Montgomerie," the 38-year-old Bjorn, whose last appearance was in the 2002 victory at The Belfry, told reporters after his round.
Both Montgomerie, and his American counterpart Corey Pavin, are checking out the course for themselves. Montgomerie outscored Pavin, with the Scot carding a two-under-par 69, while Pavin struggled to a one-over-par 72.
Dougherty, who finished fourth in the event last year, played a magnificent chip at the last for his fifth birdie, while 49-year-old Frost is attempting to become the oldest winner in Tour history.
Glasgow-born McLean, a 38-year-old who took up the game seriously only after National Service in South Africa, birdied two of the last four holes to make it a four-way tie.
Last week's European Open winner Christian Cevaer had a day to forget. Five-over-par after 12 holes, the Frenchman quit because of dizziness and stated: "The last few days have taken a terrible toll on me physically and mentally. I've hardly slept since Sunday due to a combination of my win and (management) problems off the course, which are causing me a lot of stress and turmoil."
