The Young Tennis Player ($15.95; April 16, 1996; 45 pp.; 0-7894- 0473-7): Tennis champ Vicario provides an introduction and commentary for this deconstructed view of the equipment, clothing, moves, attitudes, and rules that comprise the popular sport of tennis. The DK format (widely recognized, much-imitated) offers instant access to information on the skills, techniques, scoring, and etiquette required of all players, and some of the tips used by pros. Full-color photographs, drawings, and diagrams of the action will make most readers put down the book and pick up their rackets. (glossary, index) (Nonfiction. 7-13)
