The 19-year-old player from Northern Ireland had a 54-hole total of 13-under 200 to lead a group of six players bunched on 204.

That group included Robert Dinwiddie, who shot the low round of 64.

Defending champion Brett Rumford, who shared the overnight lead with McIlroy, shot 73 and dropped seven shots behind the leader.
