In men's tennis, the players who have won all four Grand Slam titles at least once in their careers are often referred to as "Grand Slam Champions." However, the term you might be referring to is "Career Grand Slam," which means a player has won each of the four Grand Slam tournaments. The men who have achieved a Career Grand Slam are Rod Laver, Fred Perry, Don Budge, Roy Emerson, Andre Agassi, Roger Federer, and Rafael Nadal. It's important to note that Rod Laver is the only male player to have won the Grand Slam twice, once as a non-Open and once as an Open era player. In women's tennis, the players who have achieved a Career Grand Slam are Margaret Court, Maureen Connolly (also known as Maureen Brinker), Doris Hart, Shirley Fry Irvin, Steffi Graf, Serena Williams, and Martina Navratilova. Maria Sharapova has won all four Grand Slam titles but not in the same calendar year, which is a different achievement known as the "Non-Calendar Year Grand Slam." read more >>
