It features tournaments with lower prize money and ranking points compared to the main tour, allowing emerging talents to gain experience and improve their skills. Players on the Challenger Tour can earn valuable ranking points, which help them qualify for larger tournaments. The tour is essential for developing players, as it provides opportunities to compete against others at a similar level and to gain exposure in the professional tennis world.
