Clay courts are a type of tennis surface made from crushed brick, stone, or shale. They are known for their distinctive red or green color and provide a slower playing experience compared to grass or hard courts. The surface allows for a higher bounce of the ball, which can affect the style of play, favoring baseline rallies and strategic shot placement. One of the most famous tournaments played on clay courts is the French Open, held annually at Roland Garros in Paris. Players often need to adjust their techniques and footwork when competing on clay, as the surface can be slippery and requires more stamina for longer rallies.
