Ryan Armour was 1 over par in his first round at the Sony Open when he stepped on the tee at the par-3 17th.
One swing changed his day.
He watched as his 6-iron left the clubface and barreled toward the pin, landing in the middle of the green and rolling into the cup as if it were a 20-footer.
The hole was playing 204 yards Thursday at Waialae Country Club and it was just the sixth ace at the 17th in the last 40 years, according to the broadcast.
