I had a doubles match recently, and lost mainly to lack of practice and poor volleys. However, I found it absolutely difficult to return a low, extremely fast serve. It had an about knee-high bounce, little spin. I know that many players I've faced who don't necessarily have the best groundstrokes employ this type of serve. I've been frustrated ever since; I've never been able to return this. I can return heavy kick serves pretty well, though, bouncing about head-height. I was able to make contact with these low bouncing serves, but I either shot directly into the net or shoot too far out. Is there a way to return these in? Most of these went towards my forehand side (left side). Some serves just hit the frame of the racquet, some went did on the sweetspot, but caught the net on the return.
