The recent graduate of Duke University posted 2-under 140 in the Lakewood, Wash., sectional qualifier to book his place at Erin Hills. This will be Greyserman's first U.S. Open start. He qualified for the 2011 U.S. Junior Amateur and 2015 U.S. Amateur. He almost pulled out of his North Caldwell, N.J., local qualifier due to a scheduling conflict but decided to play because "he had already paid his [$200] entry fee." The U.S. Open will be Greyserman's second start as a professional after he missed the cut in a Mackenzie Tour-Canada event in British Columbia a few days before the June 5 U.S. Open sectional.
