With the recent developments in measuring golf ball lie, it is now possible to investigate the effects of ball lie on accuracy and distance of a golf shot.  Kentucky bluegrass [Poa pratensis (L.)], creeping bentgrass [Agrostis stolonifera (L.)], and tall fescue [Schedonorus phoenix (Scop.) Holub] were mown at heights ranging from one to ten centimeters to represent golf course conditions.  Two golfers hit five golf balls from various lies with a seven iron.  Shots were measured for spin rate, carry distance, and shot velocity using a golf ball tracking radar system.  Ball lie had a significant effect on spin, carry distance, and club and ball velocity.  From this study, a more precise understanding of the effects of golf ball lie on shot quality was achieved.  Although ball lie was significant, it cannot be used alone to predict shot quality.
