Answer
Clay was Gustavo Kuerten's preferred surface. The Brazilian tennis star, known as "Guga," excelled on the red dirt, winning three French Open titles (1997, 2000, 2001) and reaching the semifinals or better in nine of his 16 appearances at Roland Garros. Kuerten's exceptional footwork, topspin-heavy groundstrokes, and ability to slide and retrieve shots on clay gave him a significant advantage over his opponents on this surface.
