world number one

Leads the rankings

World number one is the top-ranked competitor in a sport's official rankings, typically tennis, golf, or snooker: She became world number one after winning the Australian Open.

The phrase functions as both a title and description—you can be the world number one or simply world number one.

It implies current dominance rather than historical greatness.
