Rory McIlroy has been frustrated the first two days of the WGC-Cadillac Championship at Trump Doral. It boiled over on Friday, with one of McIlroy's clubs paying the price.
McIlroy's second shot from 222 yards to the par-5 eighth found a water hazard. In response, McIlroy hurled his club into the water after his ball.
The world No. 1 went on to make bogey on the hole and left to play the rest of his round with 13 clubs.
