THE MODERATOR: Hideki Matsuyama, 4-under 66, 2-under for the championship.
You like playing in US Opens, I think. You've gone low before. Why do you play so well at a U.S. Open?
HIDEKI MATSUYAMA: Actually if I have the great match, I feel it's a great test for all the players. I feel like I was playing really great today, so everything...
Q. How hard is to go bogey-free like you did on this course today?
HIDEKI MATSUYAMA: Yeah, it's very difficult obviously. Really had difficulty on this golf course. But I was able to have a good par save. So hopefully I can keep that momentum through the weekend.
Q. What was the best thing about your game today? Was it your putting? Irons? Chipping?
HIDEKI MATSUYAMA: Yeah, I feel like my short game was on point today. That really helped my game.
Q. Where you made three birdies in a row, can you describe how you made those birdies?
HIDEKI MATSUYAMA: 3 and 4, it was great shot and great putt. Had a really good momentum.
5 I hit the tee shot left. I was able to recover from there. It was about a 10-footer birdie putt. It was really good flow.
Q. You put yourself in a position to now win this championship. How do you feel right now about your position?
HIDEKI MATSUYAMA: I feel like my short game is really good. Feel like there's plenty of adjustment to my iron game. Hopefully I can adjust that through the week.
