VILAMOURA, Portugal (AP) -- Bernd Wiesberger of Austria birdied six of seven holes in one stretch Saturday, finishing with a 6-under 65 for a one-stroke lead after three rounds at the Portugal Masters.
Wiesberger, who started his birdie run at No. 8, was at 13-under 200. He was followed by England's Ross Fisher, who began the day in the lead and finished with a 69.
"I played beautifully on the back nine,'' said Wiesberger, who is going for his third European Tour title of the season. "After seven holes I was not thinking about a 65. I had some horrible wedges early on, but I grinded through that and hit better shots around the turn.''
Ireland's Shane Lowry (67), England's Richard Finch (66) and New Zealand's Michael Campbell (67) were four strokes behind the leader at Oceanico Victoria Golf Course.
Fisher played with a strained ligament in his left foot that he injured Friday.
"It was heavily bandaged and I tried to take the weight off it as much as I could,'' he said. "It's quite bruised, but the swelling is not as bad as I was told it might be.''
Spain's Miguel Angel Jimenez (68) and England's Mark Foster (67) were at 205.
