On a normal PGA tour stop, there are about 1500-1700 par 3's played that week, and on average, about one ace per tournament. So let's pretend this guy is as good as a PGA pro, and the par 3 was an easier pin placement than they typically see on Tour, so let's put his odds of an ace on a par 3 at 1,000 to 1.
Acing three of those in a single round, even at those ridiculously low odds, would be a 1 out of 1,000,000,000 proposition.
Now you factor in that not one but TWO of his aces were supposedly on par 4's. In the history of the PGA Tour, there has been ONE ace of a par four. One. And this guy supposedly had two in the same round.
There is basically no way that this occurred.
