Among clay court tournaments, the French Open at Roland Garros is known for having one of the slowest surface speeds, largely due to its unique, coarse clay composition and the way it's prepared, which retains moisture and creates a heavier, more consistent playing surface. Other tournaments that are recognized for slower clay courts include the Monte-Carlo Masters and the Italian Open in Rome, where the clay is also thick and less finely ground, contributing to slower ball speeds. The slower nature of these surfaces tends to favor baseline players with strong defensive skills, as points tend to be longer and rallies more intricate compared to faster clay courts.
