(On his decision not to go to the Olympic Games)

"I didn't feel any pressure being last. Listen, this was probably the hardest decision I've ever had to make in my life at 22 years old. I can probably honestly say that. This was harder than trying to decide what university to go to. Whether to turn professional and leave school. This was something I very much struggled with. I bounced back and forth with, and ultimately a decision had to be made yesterday, and so I made it."

(On why the decision was so hard for him)

"Why was it so hard? Because I'm a huge believer in Olympic golf. I'm a huge believer in playing for your country, showing I absolutely look forward to Summer and Winter Olympics. It's the most exciting sporting event for me to watch on TV and to have a chance to be a part of it is something I definitely look forward to trying to do. This year I just had to try and weigh a risk that doesn't present itself every year, and just at the time that I had to make the decision, I just felt this was the right move for me."

(On Olympic golf)

"It's something I've looked forward to since 2009 when it was announced, '10. But I'll make it a goal to be at Tokyo in 2020. I'll make it a significant goal, and this will be very... it will be really, really tough to watch. I just had to make a decision yesterday and weighing risk and health concerns, I made it this route."
