Sydney: Former US Open champion Geoff Ogilvy fired an eight-under-par 64 to move into the outright lead at the Australian Open and set up a final round showdown with two-time major winner Jordan Spieth on Saturday. Ogilvy, 39, was 11-under-par and two shots ahead of American Spieth, fellow Australian Aaron Baddeley and New Zealand’s Ryan Fox with one round remaining at the Royal Sydney Golf Club. Veteran Australian Rod Pampling was one shot further back after a third round 70 while world No. 7 Adam Scott carded a tumultuous 71. Scott joined fellow Australians Jake Higginbottom, Jason Scrivener, Lucas Herbert and James Nitties in a five-way tie for sixth at seven-under.
