Clay Court

The Clay Court is a tennis court that appears in all Mario Tennis games. In Mario Tennis for the Game Boy Color and Mario Tennis: Power Tour, it is where the senior-ranked players play. Alex, Nina, Clay and Ace also play here to try to advance their way to varsity-ranked. Its ground is an orange-like color in all games. It has a slow speed and weak bounce, making a harder court to play on. Defensive or fast characters are put to a slight advantage due to their statistics.
