Last week we talked about footwork and preparation for the overhead. This week we exam the options based on what type of lob you're given.
A high and short lob that drops straight down - let the ball bounce and use your quick feet to get in position to hit an angled overhead put away
A looping/topspin lob that's also short - take this ball out of the air, if it bounces you may not catch it
A well hit lob going over your head - just try to tap the ball back deep to stay in the point, or if you are athletic - jump and hit the overhead a la Pete Sampras
A very deep, high lob - let the ball bounce, move into position and hit a slice overhead similar to a serve, or even hit an aggressive ground stroke to gain control of the point
Fast feet, early preparation, and proper shot selection will improve your overhead. As a matter of fact those 3 things will improve every shot in tennis, except maybe the serve.
