Golf-Spieth in three-way playoff for Australian Open title

SYDNEY, Nov 20 (Reuters) - World number five Jordan Spieth will take on locals Ashley Hall and Cameron Smith in a playoff for the Australian Open title after all three finished on 12-under-par at Royal Sydney on Sunday. The 23-year-old American, winner of the Stonehaven Cup in 2014, sank a six-foot par putt at the 18th for a three-under 69 to join clubhouse leaders Hall and Smith, who both shot 66s. The trio will replay the par-four 18th hole until a winner is determined. (Editing by Peter Rutherford)
