Regarding usage of hyphens for numbers with preposition

Here are few examples of hyphen usage I found (albeit on internet) for numbers with preposition in between. At the same time I find these without hyphens in similar usage.

1. #-for-#
   • [Barry] "Bonds went 3-for-4 and scored three times" ESPN
   • [Barry] "Bonds went 3 for 4 and scored three times" WashingtonPost
2. #-of-#
   • "The forward posted 12 points on 5-for-9 shooting from the floor and a solid 2-of-5 behind the arc." NBA
   • [Damion] "Lee went 2 of 6 from 3-point range." NYTimes
3. #-to-#
   • "Andover Hall is the early favorite at 2-to-1 odds, …" NYTimes
   • "For instance the latest betting lines for UFC Fight Night in Cincinnati have instilled the favorite at 2 to 1 odds." Fox

So my question is, are their any rules of hyphen usage for numbers that are glued together with a preposition? If there is a rule, then a reference to the rule will be greatly appreciated.

The only rule that seems to exist is … when it is used to describe a noun and the description is before the noun with the unit involved always in singular form (e.g. inch) like so.

• #-by-#-unit
  • "Line the bottom and sides of a 13-by-9-inch cake pan with foil, …" LATimes

I believe #-by-#-unit case falls under Rule 4 of The Blue Book of Grammar and Punctuation: Hyphens but I wonder if anyone will raise an eyebrow if the above example was written without hyphens like: "Line the bottom and sides of a 13 by 9 inch cake pan with foil.
