Dr. Paul Palmer, Phoenix, Ariz. physician and surgeon, taught himself to play tennis and decided his five children should learn too. Years of patience in teaching them the basic fundamentals has produced for Dr. Palmer the makings of a real family tennis dynasty. His eldest, Patsy, 13, has already won city and state women's titles and the National 13-and-Under Hard Court Singles Championship. Paul, 12, holds state and Southwest junior titles. Victoria, 9, is Southwest 15-and-Under champion and at 7 won the National 13-and-Under Hard Court Doubles. Six-year-old Abigail won her first tournament in December, a state 13-and-under title. Butch, 4, has been playing tennis 18 months; too young for tournaments, he is shown here building basic strokes.
