Adam Scott and Rory McIlroy head to head THE Australian Open has its dream showdown. In one corner, Adam Scott. In the other, Rory McIlroy. Scott, chasing the triple crown, has a two-shot lead. McIlroy, chasing his first victory of the year, has the momentum. Regardless of the result, tournament organisers already have victory after Scott and McIlroy finished the second round at Royal Sydney atop the leaderboard, assuring another day of box office gold. If Scott was the undoubted star on the opening day, McIlroy answered in kind yesterday. The Ulsterman fired the day's best round - a seven-under-par 65 which took him into second place, only two shots behind Scott (70).
