    Abstract: A tennis racket has an elongated handle defining a longitudinal main axis and having an outer end and an annular frame fixed to the outer handle end and bisected by the axis. The frame has an arcuate crown concave toward the handle and an arcuate throat concave toward the handle and of substantially the same transverse size and curvature as the crown. The crown and throat are formed with respective longitudinally aligned sets of longitudinally throughgoing and transversely spaced holes. In addition the frame has a pair of sides substantially symmetrically flanking the axis and longitudinally bridging the crown and throat. These sides are formed with respective transversely aligned sets of transversely throughgoing and longitudinally spaced holes. The crown and sides together define an oval outer periphery.
