"It's an honor to play well in this quality of company," McCoy said following last years U.S. Senior Open. "These guys you've admired your whole career, they've done so much. It's a thrill. I'm glad that there's room for the amateur in this championship."

McCoy, a 2015 Walker Cuper arrives at Scioto Country Club with a long career of success in USGA events, including capturing the 2013 U.S. Mid-Amateur. The Des Moines, IA resident is a five-time Iowa Amateur champion and a Hall of Famer. McCoy has had strong showings this year at the Coleman Invitational (T2) and the George C. Thomas Invitational (3rd).

Some of the other top amateurs in the field include 2014 U.S. Senior Amateur winner Patrick Tallent of Vienna, VA and recent British Senior Amateur winner Chip Lutz of Reading, PA.

When Lutz claimed the British Senior Amateur last week, he became the sixth consecutive American to win the title. Lutz, the 2015 U.S. Senior Amateur winner, was also victorious earlier this season at the George C. Thomas Senior.
