A tennis tournament is a competitive event where players or teams compete against each other in the sport of tennis. These tournaments can vary in size and format, ranging from local competitions to major international events like the Grand Slam tournaments, which include the Australian Open, French Open, Wimbledon, and US Open. Players earn points and prizes based on their performance. Tennis tournaments are typically organized in a knockout format, where players face off in matches, and the winner advances to the next round. The final match determines the champion of the tournament. Tournaments can be held on different surfaces, such as grass, clay, or hard courts, each affecting gameplay and player performance.
