My goal in Korea is to win. There's no timetable when to set the American record.

We didn't see ourselves as the spoiler. Our goal was to win that relay and set the record and we did it.

That's what has always been good about track. The goal is very clearly defined: Try to win. Get the gold medal. And I'm able to put my energy toward that.

I always try to do better than I have before, so I think it would be good to break the world record.

We're going to Tulsa to win it all. That's the goal that this team set in January and we're committed to seeing it through.

Track and field is tougher physically, but golf is tougher mentally.
