Bayfield tennis pro Vivian Edwards, left, is making the switch to pickle ball, another outdoor racquet sport she said is much easier on her kneees. Edwards won a bronze medal in the pro division of the LeMaster-Davison classic on April 10 in Surprise, Ariz. <br><br>Pickleball is a racquet sport that combines elements of badminton, tennis, and table tennis. Two, three, or four players use solid paddles to hit a perforated polymer ball, similar to a wiffle ball, over a net. The sport shares features of other racquet sports, the dimensions and layout of a badminton court, and a net and rules similar to tennis, with a few modifications.
