Kevin Na has finished in the top 15 at two of the past three U.S. Opens, so he knows a thing or two about contending at the national championship. Check out his video showing how gnarly the setup for the 117th edition of this tournament will be.

Erin Hills is a great design course but the fescue is almost unplayable. BTW never found the ball. So don’t hit it in there lol. straight hitters have a chance! #usopen #erinhills #mikedavis #lostball #usga
