Normally, trying to stretch the opponent works very well in tennis. It is much
harder to hit a serve when stretched than when in balance. Sometimes you get into a match in the returner is doing great returning those serves, even
stretch. It is very important than that you try
to jam them. That you try to slice into the body. A
lot of people prefer to reach to the ball than to hit balls that are hit within their body. So don’t forget the slice
serve into the body. It can be a real weapon.
