(CNN) -- British golfer Bradley Dredge is on course for his first European Tour victory in four years after taking a three-shot lead into Sunday's final round of the BMW International Open in Germany.
The Welshman, ranked 173rd in the world, fired his second successive five-under-par 67 on Saturday to move clear of England's Ross Fisher and surprise package Simon Thornton.
Dredge, who led by one stroke at the halfway stage, carded another flawless round and has now not dropped a shot since a bogey at No. 3 on Friday.
He carded three early birdies including a 50-foot chip-in, and then picked up more shots at 11 and 13 before parring his last five in Munich.
"It was not the prettiest, but my short game was good again and you've got to be happy with a 67 on the third day," the 36-year-old told the European Tour website after taking his total to 18-under 198.
"I'll be keeping an eye on the board tomorrow and I hope I will be able to assess when to be aggressive or when I can play safe."
Fisher reduced Dredge's four-shot lead at the 45-hole mark as he began his back nine with a birdie and then an eagle, but a bogey at 14 slowed his progress before he picked up another shot at 16.
"I think I am capable of shooting very close to 60. I feel like there's a ridiculously low round in me," the world No. 39, who has struggled this year after winning the 2009 World Match Play, said after a second successive 66.
"This week is probably as good as I've hit it for a long time. It reminds me of when I breezed around Wentworth in 64 last year."
England-born Thornton, who now has an Irish passport, shot a third successive 67.
"I'm just telling myself to stay in the present. I could shoot 10-over tomorrow and it would all be a waste of time, but I hope I won't," said the 33-year-old world No. 627.
"Somebody said at the start that you'd take four 67s this week -- and there's three of them. I've never been in the final group before and I'm looking forward to it."
Former British Open champion Paul Lawrie of Scotland was fourth on 202 after a 68, with compatriot Peter Whiteford (70) tied for fifth another shot back with Spain's Ignacio Garrido (70) and Englishman David Horsey (67).
Meanwhile, England's Justin Rose took a four-shot halfway lead at the PGA Tour's Travelers Championship event following a second-round eight-under-par 62 on Friday.
Rose made five successive birdies on his back nine to storm clear of American Kevin Sutherland, who shot a second consecutive 65.
Sutherland was five strokes clear of Vijay Singh (66), Corey Pavin (66), Bill Lunde (63) and Charlie Wi (67).
