Steven O'Hara of Scotland shot a flawless 7-under 65 Saturday to share the lead after the third round of the Czech Open.
O'Hara made seven birdies to join Oliver Fisher of England (68) at 10-under 206. Gaganjeet Bhullar of India shot a 64 for a share of third place with Gary Boyd (70) of England and Mikael Lundberg (68) of Sweden, who are two shots back.
''I've been guilty of changing my putter every other week in the past, but I've found one I like and I'm in a good groove on the greens now, so I think I'm just going to stick with it,'' said O'Hara, who is aiming for his first career European Tour victory.
Fisher, also winless so far, had an eagle on the 11th.
''I had a lot of fun out there,'' Fisher said. ''It's where you want to be, not struggling to make the cut.''
Earlier Saturday, Lundberg completed a 68 to take a short-lived, one-stroke lead after the rain-delayed second round.
Anthony Kang of the United States shot a 69, six strokes behind the leaders.
