A "grand slam" can mean two different things in tennis. Most people consider a "grand slam title" winning one of the four majors (Australian Open, French Open, Wimbledon, and the US Open) However, it can also mean winning all four of these events. If this is done during one season, it is most often referred to as a Calendar Slam (but can also be called a Grand Slam) and if a player wins all four of these events over the course of their career, it is accordingly called a Career Slam. Both are very rare.
There is no biggest tennis ball. the normal tennis ball has 6.7 cm as diameter.
No. Only top professional tennis players can compete for the title.
