Starsnuffer is OK for perhaps travel ball, but isn't going to work in college. In college ball, pitchers face the same batters over and over again. There really aren't any secrets or surprises.
The batters are aware of their own strengths and weaknesses. So, a pitcher can't say "oh, she can't hit the inside pitch, so I'll throw her a dozen screwballs." The batter has already found a way to compensate for it.
The most important single factor is the umpire's strike zone and coming up with a way to exploit the zone. The next most important factor is determining what pitches the batter likes and what pitches she doesn't like.
