Andrew Dodt stormed into a one-shot lead in the third round of the BMW PGA Championship after posting a round of 68.
Dodt, 31, began the third round three shots off the pace and fell further behind with a bogey at the par-5 fourth, but the two-time European Tour winner bounced back superbly by rolling in five birdies over his final 11 holes to reach 8-under and open up a narrow one-shot lead over South African Branden Grace, who carded a round of 70.
The Australian won the 2010 Avantha Masters and 2015 Thailand Classic on the European Tour.
England's Lee Westwood (72) birdied the final three holes to move up to 5-under alongside Italy's Francesco Molinari (74).
Joint tournament favourite Henrik Stenson fell out the gates with three bogeys on his first seven holes but birdied two on the back nine to card a round of 73 to lie 4-under and four shots off the lead alongside Ireland's Shane Lowry (70) and Japan's Hideki Tanihara, who posted a best-of-the-day 67.
English quartet Ross Fisher, Tyrrell Hatton, Andrew Johnston and Graeme Storm, Thai Kiradech Aphibarnrat, Welshman Bradley Dredge, German Maximilian Kieffer and Scotsman Scott Jamieson sit five shots off the lead on 3-under.
