This is a neat cooperative drill for intermediate players which focuses
on groundstroke and volley control. 4 Players (A & B; and C & D) are stationed
in the normal doubles positions of one-up, one-back. Players remain in
these positions throughout the drill. The instructor stands off to the
side near the service line.
The drill begins with the instructor feeding a ball to baseline player
A in the deuce court, who hits a controlled groundstroke back to the net
person C. C volleys this ball cross-court to B on the opposite service
line. B volleys this ball deep to D standing on the baseline. D then hits
a controlled cross-court groundstroke back to A on the baseline and the
sequence continues. After several minutes, rotate the players clockwise.
You can see how many "around the horn" sequences the four players can
make. Or, after one complete sequence, with the ball coming back to A,
the players can then play out a point.
I like to use this drill as a measure of my students' progress by only
employing it once a month or so.
