SuggestedLeadIn: World number one Jordan Spieth looks ahead to The Barclay's tournament at Plainfield Country Club and discusses the FedEx Cup playoff system.

Script: SOUNDBITE (English) Jordan Spieth:

(On being world No. 1)

"I'm happy to be in that position now. But I'd like to obviously hold it. And I don't know exactly what that entails. I don't know the feeling of trying to hold No. 1 because now you're the one with the target and everybody else is chasing towards that position. The only way I think about going about it is just focusing on this week, to... If you win each week, you're going to stay No. 1 and in my mind, that's the goal is to approach each tournament to try and win and then try and keep this position for hopefully years. But again, it can change in two weeks' time, so I'm aware of that. And that bit of fear on the back end of it is enough to get me going and to keep working hard."

(On where he puts prestige level of the FedExCup)

"So it's interesting. I don't know exactly where I put it. It's something obviously everybody wants to win, there's no doubt about it. But I think it's a little odd that it just completely resets, because if you want it to be the true champion of the year, then it wouldn't necessarily reset for the final, even if you do make it worth more points throughout the year. I mean throughout the playoffs."
