In the context of a clay court final, a question arose regarding the cleanliness of the tennis balls compared to the dirty shoes of the players. It was clarified that the balls are changed regularly during matches, which contributes to their cleaner appearance. The discussion highlighted that the balls spend less time in contact with the ground compared to the players' shoes, which are constantly in contact with the clay. Additionally, the impact of the rackets hitting the balls may help dislodge some clay dust, keeping the balls cleaner. Observations were made about the performance of players, particularly praising Nadal's skill during the match.
