Tennis is a sport that can be played both individually and in pairs. While some players excel in both singles and doubles, many find that the strategies used in one do not necessarily work for the other. The top players in doubles are often very different from the top players in singles, as the game requires different skills and tactics. So, while some players may find success in both singles and doubles, it is rare to see the same players at the top of both rankings. Ultimately, success in tennis comes down to mastering the unique skills and strategies of each game.
