Definitely my iron play. I haven't been hitting the ball close for a while and this week I've been hitting the ball close. I think I've hit a lot of greens, but also hit it close a lot. I've just had a lot of good birdie chances.

The last year or so for me have been anxious, not being in contention very much.

I still believe that in the end, you have to putt with feel. Tools tend to take away the feel.

I read putts with my feet.

It's been a long time since I've been on top. It's nice. But on a course like this, you've got to keep your focus. If you've got the opportunities to keep shooting for birdies, you've got to do it.

Instead of 30 or 40 feet, I'm in there at 20 feet. When I hit a good shot, I'm inside 10 feet. I've hit a lot of greens this week but I've also hit it close a lot. Just a lot of good birdie chances.

Some of those are pretty complicated. But you tend to make putting complicated, in general. You [should] use the [tools] to get a feel to get a good groove. Some of them help you with your feel, others help with your alignment.

(In golf) I think kids are peaking sooner but I don't know if that necessarily means they'll be able to carry that into their late 30's. I think that remains to be seen.

It has been a long time since I've been on top so it's kind of nice. You've got to keep pushing and making birdies and that's what I've been doing for two days. Hopefully I can continue that.
