Greg Chalmers is clinging to a two-shot advantage late in the final round of the Emirates Australian Open, with Tiger Woods leading the chasing back just two shots back. Chalmers produced a birdie at the par-four 13th to move to 12-under for the tournament, two clear of Woods, Nick Watney and Jason Day. Woods, who began the day six shots behind overnight leader John Senden, produced three birdies on the opening nine to turn in 32 strokes. He produced bogeys either side of a birdie at the 12th before igniting his round, and the massive gallery following his every move, with a chip-in for eagle at the par-five 14th to close within one shot at the time. Watney also produced eagle at the 14th to vault up the leaderboard, while Day, who shared the lead with Chalmers for several holes, bogeyed the 11th to fall back to 10-under overall. Defending champion Geoff Ogilvy (65) and Adam Scott (68) share the clubhouse lead at minus-nine, alongside Ryan Haller, Nick O&aposHern and overnight leader Nick O&aposHern who are yet to complete their rounds. Ogilvy&aposs day included six birdies and an eagle at the par-five 11th to close within two of the leaders when he walked off the 18th green. Scott&aposs charge included three birdies and an eagle on the back nine to finish a solid week. American Kyle Stanley and Aaron Baddeley sit a further two shots back late in their final rounds, while Bubba Watson is a further stroke back. Kelly Kraft (72) pipped Ryan McCarthy (71) by a shot to finish the top amateur at three-under par.
