Unfortunately I haven't seen Lauren Delaney pitch too much this season, but from experience it really depends on whether she just just pitching inside a lot or if she is a truly wild pitcher.  If she is just a pitcher who pitches inside a lot then the HBP is incidental and there's nothing you can do.  But if she is wild then it is up to the conference and the NCAA to look at the tape to figure out if she's endangering anyone and whether action needs to be taken (which is usually a warning and a call to the umps to make sure to keep an eye on the pitcher's control).  Regardless it has to be taken on a game-by game basis and it is up to the ump whether she is a threat to the opposing batters. 

As a hitter it can change your mindset coming up to the plate and Delaney might gain a psychological advantage if the batter is afraid to be hit.
