Non-Volley Zone
No player may volley a ball while standing in the non-volley zone or touching any of the lines around the non-volley zone. A player may enter the non-volley zone to play a ball that has bounced and may stay there to play other balls that bounce, but the player must re-establish both feet outside the non-volley zone before playing a volley. The non-volley zone is the highlighted area and numbered lines shown in the "Service out" diagram. Unofficially, the non-volley zone is commonly referred to as "The Kitchen".
