Jamie Donaldson shot a 6-under-par 66 on Thursday to take first-round lead at the Czech Masters and boost his chances of securing a spot on the European Ryder Cup team.

Seeking his third European Tour victory, the Welshman produced two straight birdies on his last two holes to top the leaderboard. He made a total of eight birdies and two bogeys at the Albatross Golf course near Prague.

''I played nicely all the way, really,'' Donaldson said. ''I just need more the same over the next three rounds. There's a lot of difficult holes.''

Sweden's Mikael Lundberg was one stroke back in second place, with a group of 10 players carding 68.

Donaldson currently has a qualifying spot for his debut Ryder Cup but still needs a good result to guarantee a place in Paul McGinley's team for next month's match against the United States at Gleneagles.

Two other Ryder Cup hopefuls - Stephen Gallacher of Scotland and Joost Luiten of the Netherlands both shot 70.

Play was delayed by an hour due to lightning.
