I have odd hitting troubles.

I am a fairly decent hitter. I am currently hitting .453 on my school team, but I am currently incapable of hitting hanging breaking balls. I either pop them up or whiff. I usually destroy ones that bite, and I can hit virtually every other pitch well. Does anyone have pointers on hitting hanging breaking balls? I know it's a weird question, because everyone else can hit them. I've spent countless hours working with people throwing me breaking balls, but I can't hit the hangers.

TL;DR Any advice on how to hit hanging breaking balls?
