NO. 6 Speed, Accuracy, Break Are Most Important to Get Into Your Service Sixth of [__] instructive articles on streamlined tennis By MARY K. BROWNE Famous Coach and Three-Time National Women's Singles Champion Speed, accuracy and break -- in that order -- are the most important things to get into your service. Break used to be very important until Don Budge murdered the first break service in tennis -- that of Baron Von Cramm -- by standing inside the base line to receive it and taking it high before the ball had time to break severely.
