Still adjusting, McIlroy resumes battle with Tiger

World No 1 Rory McIlroy will be keen to dispel any doubts about the impact of his equipment change in this week's Honda Classic, where he comes up against a field featuring Tiger Woods.

McIlroy is the defending champion at the PGA National course after a victory last year that sent him to the top of the world rankings for the first time.

Since that win, where the Northern Irishman held off a late charge from Woods, McIlroy has claimed three more victories, including the PGA Championship.
