Standing close to the baseline not only helps you when your
opponent is out of position. This court position simply
cuts down your opponent's time everywhere on the court.
Whether they are at the net or on the baseline, your opponent
will have less time to react after each of your shots.
This will put extra pressure on your opponent to hit a good
shot and may force more errors from your opponent. If
your opponent is a slow mover this is a great strategy to
employ. If you are well behind the baseline to hit your
shots the ball will be slower when it gets to your opponent
and it allows your opponent more time to get to the ball and
be more offensive.
The same reasoning is true for your volleys. The closer
you can get to the net to hit your shot the less time your
opponent will have time to react. Coming to the net
to hit volleys is the ultimate way to rob your opponent of
recovery time and it puts immense pressure on your opponent.
To hit the ball on the rise takes a lot of practice as it
is not an easy task to accomplish. Hitting the ball
on the rise will take better coordination and will require
you to act faster and takes complete concentration.
However, you will win more points and put more pressure on
your opponents if you are able to do it. Practice hitting
the ball off of the rise and see how it can improve your game
and make life for your opponent(s) less pleasant.
Good Luck on the Court!
