PERTH, Australia (AP) — Thorbjorn Olesen's bunker shots and putting helped him grind out a 5-under 67 Saturday to lead the Perth International golf tournament by three strokes after the third round. Olesen of Norway had six birdies and a bogey to reach 16-under after three rounds, matching the score that won the inaugural tournament two years ago. Olesen demonstrated an outstanding ability to scramble as he saved pars or made birdies from difficult positions. Jason Dufner, the 2013 U.S.
