Rahm, 28, took aim at a cameraman while looking for his golf ball down the right flank on the par-4 8th.
This came just three holes after Rahm smashed up a microphone when shanking a chip shot.
As Rahm trudged around the rough looking for his golf ball with his caddie Adam Hayes, he took one look at the man behind the lens.
"Stop aiming at my face when I’m mad... it's all you guys do," said Rahm.

“Stop aiming at my face when I’m mad.. it’s all you guys do.”
Rahm ended up shooting a 72 to take him back to 6-over par and well out of contention for the title.

The World No.1 opened with bogeys at 1 and 2 and despite making birdie at 4 quickly handed it back with a bogey at 5 aided by his chip shank.
Rahm then made bogeys at 8 and 9 to go out in 39 shots.
He bogeyed 10 to fall further back but rallied later in the day with three birdies on the last six holes.
Rahm yesterday dropped a shocking F-bomb that he aimed directly at the PGA of America.
