O'Hair said the club will add 20 yards to the par-4 No. 18, too, turning a tasty birdie chance into a tight, bunkered, 460-yard, risk-reward finisher.
"That's going to make it a completely different hole," O'Hair said.
It will be a significantly different course.
"I'm definitely looking forward to it," O'Hair said. "I know a lot of the people in Philadelphia will be, too. It's going to be fantastic. I'm excited to be a part of it, where I live."
