DURBAN, South Africa, Jan 11 . – A birdie at the 18th nudged Briton Tommy Fleetwood into a one-shot lead at 10 under par after the third round of the Volvo Golf Champions tournament on Saturday. Fleetwood fired four birdies and a bogie in his round of 69, giving him the slender advantage over France’s Victor Dubuisson and Joost Luiten of the Netherlands. A triple bogey on the 16th cost home favourite Louis Oosthuizen the overnight lead but he will start Sunday’s final round two shots behind Fleetwood and still in the hunt. Luiten, who shot the first albatross of the European Tour season on Friday at the par-five 10th hole, Oosthuizen and Fleetwood were joint leaders going into Saturday’s round The 22-year-old Fleetwood, who won his only other European Tour event when he claimed the Johnnie Walker Championship in a playoff at Gleneagles last August, went out in 33 on the front nine, but had to wait until the 18th for his next birdie having dropped a shot on the 14th.
