Preparing
early for a groundstroke will throw you off. You
make up your mind too soon, without observing the ball all
the way.
Instead
of trying to predict what the ball will do, stalk
it with your racquet, and make your final adjustments after
the bounce of the ball.
From
baseline to baseline, the ball slows down close to 60%. The
longer you look at it without making up your mind, the more
time you'll seem to have.
Oscar's
videos (DVDs) and book give you drills to develop excellent
timing. You'll be more natural, well coordinated, and experience
much more feel. Tennis will become an easier sport to master,
more fun than ever before.
