What has been the Rockies greatest single game pitching performance?

Ok, ok, ok, pitching, Coors Field, Mile High, altitude.  Words not commonly associated with good things for pitchers.  After several days of scouring over mountains, piles, pages, rows, columns, so many numbers that my head still hurts.  I have compiled a list of the best single game pitching performances by the Rockies and am asking for your help in determining the top spot.

I do apologize for the length of time between 1997 and the 1998 posts.  I've just been busy with a lot.  Anyway here we go:
