Oh, how do I say this?
Do I need to? A well executed backhand slice is one of the nastiest shots in tennis to deal with.
How do I know? Because I use it to a fault, perhaps not.
I use the backhand slice when it becomes so effective and affordable.
Send me a weak shot about waist or chest high and I’m giving you back a ball that is difficult to interpret and may not leave the court enough for you to have a chance at striking it.
It took years (not many) to develop this, but it works. If you can use this shot effectively in singles, then you are golden.
