Playing in his first U.S. Open, Greaser fired rounds of 72-70 to make the cut -- one of only four amateurs to survive to play the weekend. A third-round 76 and the final-round 79 left him at 17 over for the tournament and tied for 61st place.
Greaser, a rising senior who plays at the Univeristy of North Carolina, qualified for the U.S. Open by finishing as runner-up in the U.S. Amateur last summer. He also played in the Masters -- his first major championship appearance -- in April, but missed the cut.
