WATCH - McIlroy loses it and throws his club into the lake!
World number one Rory McIlroy apologised for throwing his three iron into a water hazard after more erratic play in the second round of the WGC-Cadillac Championship.
McIlroy had just recorded his third birdie of the day to get back to level par for the tournament when he pulled his approach to the par-five eighth - a hole he had eagled on Thursday - into the water.
And after a few seconds' thought the 25-year-old then hurled the offending club into the same stretch of water on his way to recording a six, his third bogey of the day.
McIlroy recovered to card a round of 70 to lie one under par, eight behind leader JB Holmes, but he admitted: "Frustration got the better of me.
"Following on from last week I feel like it's very close and to hit shots like that you get frustrated, but I shouldn't have did what I did.
"It all bottled up and had to let it go somehow and that's what happened. I don't feel good about doing it but I will hopefully have a new three iron on the way in the morning and be able to got out and play with another one.
"I wouldn't encourage kids at home to do the same thing."
