The task is even more difficult nowadays with the four tournaments all being played on different surfaces: Plexipave in Australia, clay at Roland-Garros, grass at Wimbledon and Decoturf at the US Open. Andre Agassi is the last player to have won a career Grand Slam, though his victories at Wimbledon and Roland Garros came seven years apart.
Aujourd'hui, la tâche des champions est d'autant plus ardue que quatre surfaces différentes sont utilisées : le Plexipave en Australie, la terre battue à Roland-Garros, le gazon à Wimbledon et le Decoturf à l'US Open.
