Grass presents golfers with a variety of lies. It exists in many forms and takes on different traits (because of weather, mowing, etc.), so reading lies and predicting their impact on a shot can be challenging. You hit the majority of your shots off grass, so you should know what to expect from various lies. Wouldn't it be nice to save five shots a round just from reading this? We asked Pat Finlen, president of the Golf Course Superintendents Association of America; Mike Nicolette, a PGA Tour winner turned Ping club designer; and Bret Wahl, a vice president of research and development at TaylorMade, for some advice.
