Pros make holes-in-one all the time, during pro-ams, or otherwise. But what was unusual is that Kokrak did it on a 409-yard par-4 hole.

As Shane Bacon of Yahoo pointed out, this has only happened once in PGA Tour tournament play (1:13 below) and it took a lot of luck.
Heck, in the 2013 season on tour there were only 10 drives of 409 yards or more all season. It's not all that surprising that Kokrak would be the one to do it, I guess. He finished sixth on tour in driving distance with an average of 303 yards per drive.
But it's still a pretty incredibel feat for Kokrak, I bet he wishes it would have just come one day later during the actual tournament, though.
