the book:

I see it all the time in articles by analysts, such as on Fangraphs.  UZR/150 means nothing if you don’t regress the actual UZR.  If you must quote UZR per 150, at least wait until the player has at least 150 games or so. Otherwise just tell us his UZR and how many defensive games he played.

colin pointed this out in his excellent UZR primer.
