Rory McIlroy takes share of lead at rain-affected US PGA Championship

Northern Ireland's Rory McIlroy moved joint top of the US PGA championship during a rain-delayed third round at Kiawah Island.

McIlroy produced a fine run of form to join Vijay Singh on six-under, making five birdies in a profitable eight holes.

Early leader Tiger Woods endured a bogey-laden round to slip down the leaderboard to 11th place.

Australian Adam Scott is just a shot behind the leaders as he looks to erase the painful memory of last month's Open Championship.

British duo Ian Poulter and Graeme McDowell are also still in contention, both sitting just four shots off the pace.

A thunderstorm interrupted play and forced the conclusion of the third round to be delayed until Sunday.
