Wikipedia is not a crystal ball

Please do not predict the future on Wikipedia. Wikipedia is not a crystal ball, so on February 20 or February 21, you cannot write that something happened on February 22. Wait till February 22, check a reliable source, then report that it happened. Never say that something happened when it verifiably has not happened yet.—J. M. (talk) 03:03, 21 February 2016 (UTC)

oh,sorry.I did not offense.I'm beginner of Wikipedia.Also I'm not good at English.

But I have a reliable source. My writing thing is true.It will be demonstrated February 22.

If you have any opinion,please you use easy English.I didn't understand your'sentense a little.— Preceding unsigned comment added by プレミアナガラ (talk • contribs)

No, your writing was not true (and that is not my opinion, that is a fact), and you do not have any reliable source. You said 2 things:

1. That February 22 is the past (or present). No, February 22 is the future.
2. That the #15 ranking is current. No, it not verifiably not, as you can see on the official ATP website. Which is the only reliable source. His current ranking is still #19. He may become #15 on Monday February 22, but it has not happened yet, he is still #19. You cannot predict the future on Wikipedia and report is as something that has already happened.—J. M.
