That's fine with him. In fact, he said he doesn't feel he's under any pressure this week, and that's good for him because "I play my best when I'm relaxed and having a good time.
"I feel comfortable," he said. "I don't feel nervous at all about it. I'm just going to have a good time with it, to be honest with you. I'm going to enjoy it. It's not going to be like, 'Oh my God, I've got to perform.' And I think some guys feel that way.
"I'm going to embrace the fact that this has never happened before for me and it's going to be really, really cool."
It would be cool for the home folks to see O'Hair pick up his fourth career victory in Newtown Square. He is thought by many to have the tools to eventually be a frequent winner on tour and challenge in the majors. He has a terrific game from tee to green. His putting can be an issue at times - he is 130th in putting average entering this week - but he continues to work at it.
O'Hair, who turns 28 on July 11, admits that he will achieve the next step when he can improve the mental side of his game, "making the bad days not so bad and the good days maybe just a little bit better.
"When you get things going," he said, "it's making a five-foot putt that you might miss. On bad days, it's staying away from three-putts. When you're missing shots, miss them in the proper spots.
"I think that is why you see guys like Tiger [Woods] and Phil [Mickelson] contend on a regular basis because they just don't play stupid golf. They play very smart golf. It's not always good golf but they play smart golf."
