Per NCAA scoring rules:
http://fs.ncaa.org/Docs/stats/Stats_Manuals/Baseball/baseball_softball_scorebook.pdf page 8:
z. Stolen Base: Credit given to a runner who advances a base unaided by a safe hit, putout, error, force, fielder’s choice, illegal pitch, wild pitch, base on balls, hit batter, passed ball, interference or obstruction.
a - If the runner starts for the next base on the release of the pitch
and the pitch results in what would otherwise be scored as a wild
pitch or passed bail, credit her with a stolen base (if she gets a
second base because of the wild pitch or passed bail score only the
initial base as stolen).
and
c - A stolen base is credited even if a wild throw would have resulted
in a sure putout, had it not been wild. No error is charged unless
another base is gained because of the throw.
I think you left out the part I was talking about.
