So you have a big forehand and two hand backhand at the baseline-why not use them at the service line with a swinging volley.
If your big ground strokes are causing consistent but not so powerful returns you may want to consider moving in and take many in the air with the swinging volley. If you just stay back and keep pounding the odds of an unforced error is always lurking, so too is the possibility of a long match. If you can shorten the points with a more aggressive style you will maintain the momentum and hopefully shorten the match.
What determines when a swinging volley can be hit or a conventional volley is needed? Great question! The two factors of the oncoming shot that will tell you are pace and height. You never want to try a swinging volley if the ball is below the height of the net, and it is also much more difficult if there is a decent amount of pace on the ball. In either of those scenarios please hit the conventional volley, using the Continental grip.
Is there any form difference for the swinging volley than my ground strokes? Another great question! Yes, if you have a loop backswing. You want to shorten the swing, take the racquet back shoulder high on both sides and then basically the stroke is the same with a complete over the shoulder follow through. The point of contact will also be slightly higher than your normal ground stroke.
I do not recommend a swinging volley if you have a one hand backhand for your normal ground stroke. While the shot can be made it’s more difficult.
When playing, be ready to move in if your strokes have the opponent pinned behind the baseline. Anticipate a weak return and start to move in. Always know that a stronger shot may come back requiring a switch to the conventional volley and the possibility of a lob.
Shorten the points-shorten the match!
Good Luck-Have Fun!!
