Rickie Fowler angrily pointed and shouted at a golf fan on Saturday after they disrupted him as he teed off at the Players Championship.
Fowler, a PGA Tour veteran, was teeing off on the 16th hole at TPC Sawgrass during his penultimate round of the tournament.
There was a disturbance on the tee box before Fowler had even put his ball down.
Fowler's caddy, Ricky Romano, can be heard telling a fan to 'hold the camera still and keep phones on silent'.
But as Fowler struck his tee shot, something disturbed him as he took one hand off the club after hitting the ball and didn't complete his follow-through.
Fowler then pointed straight at the fan and yelled: 'YOU! What are you doing?'
He later told DailyMail.com that it was the noise of the shutter on the fan's camera clicking that disrupted his swing.
The tense moment capped off a disastrous day for Fowler, who finished four-over par for the round.
Despite being put off during his tee shot, Fowler still managed to carry his drive 285 yards down the middle of the fairway.
However, his second shot found the water and he therefore had to settle for a double bogey as he finished with a 76 on Saturday.
It leaves him three-over for the tournament going into Sunday's final round and a mammoth 18 shots behind current leader Wyndham Clark.
