Q. Opened with a 3-under 68. What part of your game was the strongest for you today?
HYUNJO YOO: (Through translation.) The best one, No. 2 birdie I think that was the best one.
I think because I was able to get the birdie in the beginning I felt more comfortable.
Q. How did the conditions fare in the early part of your round with the marine layer out there? How did that fare with the afternoon when you finished?
HYUNJO YOO: (Through translation.) I don't think that was much difference. I think I was a little bit nervous in the beginning. As time goes I was able to relax a little bit and was able to enjoy the game.
Q. Then so you're sitting first round leader right now. What does the rest of the day look like for you as you tee off tomorrow, Friday?
HYUNJO YOO: (Through translation.) Tomorrow it'll be windy I think so I'm a little bit concerned about that. But I'm going to use the wind to my advantage so rather than playing aggressively I will play maybe more safely and I will use the chance.
