Keep it compact
Shortened backswings, serves and volleys will help you prepare in time for the fast-approaching returns on grass. Keeping your game compact will certainly contribute to your success on this fast-paced surface.
Avoid the loft
Bounce is deadly on grass. Utilize the speed of the court with flat groundstrokes for shots that really move.
Stay focused
The average rally on grass lasts four strokes. It is important, therefore, to stay focused on the task at hand. And when playing the net, even a half second lost on preparing for a return could mean the difference in a point won or lost.
Take baby steps
Wet or dry, grass can be quite slippery. Increasing the number of steps you take to prepare for a return can help you maintain solid footing. Deliberate sliding is also common on grass, though not as effective as on clay.
