WITHIN in sports journalism

[Frank Abate]

Have others noted the use of "within" in sports play-by-play reportage as in:

  "with that basket, they are now within one" [when the score differs by one
point]

I've heard it during basketball, baseball, and football games, at least.  Is
it new-fangled for one to say that the team behind is "within" the specified
number of point(s) that they are actually behind by?  OED examples at "within
prep." don't quite point out this usage, as I read them.
