An angry Rory McIlroy threw a remote controlled golf ball into the water in a bizarre incident at the BMW Championship on Saturday.
McIlroy was lining up a birdie put on the 15th hole at Wilmington Country Club when another golf ball appeared on the green.
As the ball whizzed around the flag stick of its own accord, it became apparent that the ball was being controlled remotely by a spectator declaring "I'm going to make a hole in one".
