Tennis as all other sports is the game. As it is the game everyone is competing in it. That is the sort of comparison game, where the watcher will always be comparing the players and decide who is the winner, and who is the looser. That is the nature of all the rankings, tennis first names, best players, grand slam singles ,doubles , most grand slam singles and doubles, and many other categories that had been invented and provided to measure the abilities and talents of sportsmen and sportswomen.
Tennis all time records are the ones that will always be those discovering the unusual talents of ordinary people, making them extraordinary in a way, and making them the heroes that had devoted all their lives to sport and sport lovers, who were watching them and got amazed at their achievements.
Most grand slam singles are the tennis players who had been the best and most numerous in winning grand slams of different world championships. The most grand slam single within men was Pete Sampras, who had won different grand slams for fourteen times. In his time he had been called the king of swing, the true champion and got this name after numerous brilliant victories over such tennis player, as Ivenishevic and Andre Agassi. He is the hero of the second part of the twentieth century, but there is a record for the whole tennis history, so the earlier achievements had not been forgotten.
Margaret Smith Court had been the best most grand slam single within women winning 24 tournaments throughout the world between 1960 and 1973. Margaret Smith Ccourt was Australian and won 11 Australian Championships, five United States', five French and three Wimbledon ones. Margaret Smith Court was one of the most outstanding figures in tennis. She was one of three women to achieve the triple crown getting the grand slam single, grand slam double and grand slam mixed in 1963 and 1970. The other ones were King and Navratilova. Pete Sampras and Margaret Smith Court are the most remembering people in tennis history, although there were many others like Maureen Connolly, Steffi Graf, Martina Navratilova and others.
Nobody knows how much force it cost to them to get all the skills necessary for training, all the resources, that made them available to become most grand slam singles in the whole world, to make their names be remembered. But the career of sport players is not long, but very bright and short. It is quite impossible to get stronger and stronger, getting more and more grand slams, as each of them is taking away the small part of sportsmen's life. But it's worth doing, some people say; some say it does not.
Most grand slam doubles as well as most grand slam singles winners were John McEnroe winning 152 different titles, Martina Navratilova who got 341 titles, and many others.
As there were tennis players who played only single or double tournaments, meaning the games itself, were one against one or two against two, many tennis players preferred to play mixed tournaments, and statistics had counted even these games that had happened in different times with different players. That was Margaret Smith (Court) and Ken Fletcher 1963 in women's tournaments .
