Fox hit his second ball, his third shot for the hole, straight into the hole for a hole-in-three.
The par three sixth provided his shot of the day after he went out of bounds from the tee.
The flawless shot was still well worthy of celebration as a beaming Fox high-fived his caddy and playing partner on the walk to the green.
"I can't lie, I hit the first one straight out of the hosel [socket of the club head] and straight in the bushes and re-teed it with a wedge and hit a flawless shot".
Fox was relieved no one found his first ball, which would have meant he had to play it and the hole in one wouldn't count.
Fox has finished tied for the fourth at the Scottish Open at Dundonald Links after a final round two-under 70 to take home 223,241 euros.
