J.J. Spaun conquered Oakmont for one day

It was also only the eighth bogey-free round (any round) in U.S. Open history at Oakmont. 

In the days and weeks leading up to the start of this year's U.S. Open, all of the talk was centered around how difficult this course was going to be and whether or not it would even be won with an under-par score. 

The fact that somebody came out on the first day and played it so well was a bit of a surprise. Especially when it was not even one of the favorites. 

Spaun has only won one PGA event in his career and has never finished higher than a tie for 23rd at a major. He obviously has a long way to go this weekend, and danger is no doubt lurking for the next three rounds just because that's what Oakmont does to golfers, but it's certainly a great start to the weekend.
