# Why Nadal would take ATP No.1 and overstep Djokovic if he just reaches the final?

If No. 2 seed Rafael Nadal reaches the final, he will reclaim the No. 1 ranking regardless.

Assuming that they both (Nadal - no.2 and Djokovic - no.1) reach the final, and that even Djokovic might win, why wouldn't he be able to retain it's top spot?

The tournament (China Open) started with Djokovic 1st and Nadal 2nd, and it's the only tournament they both play. From where Nadal would take his extra points?

It has to do with how rankings points are computed based on a rolling 12 months of results.

The short answer is - Nadal didn't play in the China Open last year - so he's "defending" zero points. It means he didn't win any rankings points from the event last year. So last week, zero points expired and fell from his points total.

Djokovic however, won the event last year, and got 500 rankings points because of that result. So, last week, those 500 points "expired" and fell off of his points total. So, even if Djokovic wins the event again, his points total will merely stay the same (or decrease if he doesn't win the title again) while Nadal can do nothing but increase his points total.

Here is how the math of it works out - Winning the title is worth 500 points, making the final (but losing) is worth 300 points.

Point totals Prior to China Open:

``````Djokovic   11120
``````

Djokovic's 500 points from last year expire, Nadal was defending 0 points, so nothing expires for him:

``````Djokovic   10620
``````Djokovic   11120
