The victory earned McCoy a spot in the 2014 Masters Tournament.
The 50-year-old McCoy, from West Des Moines, Iowa, is the second-oldest winner in the event limited to players 25 and older. Randal Lewis won the 2011 tournament at 54.
“It’s a great day for me,” McCoy said. “And I’m very thrilled to finally have won a championship. I’ve been trying for a long time. And I’ve had a lot of friends over the years that have won the championship along the way. They’ve all encouraged me to kind of keep battling, keep trying. And so that’s kind of what I’ve done. I really chased the dream for a long time. And it kind of came true today.”
An insurance agent, McCoy was reinstated as an amateur after a brief pro career following his college days Wichita State. He earned a spot in the Masters with victory.
“When I got dormie, I have to admit it crossed my mind a few times, but I was really trying to stay present,” McCoy said.
The 36-year-old Williamson is from Cincinnati.
