Hey all, I am looking to play some high school tennis this coming school year. I just had a couple basic questions. So, I have the whole "low-to-high" thing down but my balls are still going out, but barely. Any tips on how to hit with more topspin that actually work? How does one hit a one-handed backhand or a slice backhand? I am completely clueless on this question so any advice helps. That is all, for now! Thanks.
