Grand Slam (tennis)

The Grand Slam in tennis is the achievement of winning all four major championships in one discipline in a calendar year. In doubles, a team may accomplish the Grand Slam playing together or a player may achieve it with different partners. Winning all four major championships consecutively but not within the same calendar year is referred to as a "non-calendar-year Grand Slam", while winning the four majors at any point during the course of a career is known as a "Career Grand Slam".
