Margaret Smith Court won 24 Grand Slam singles titles: 11 Australian Opens, 5 French Opens, 5 U.S. Opens, and 3 Wimbledon. She also won 19 Grand Slam doubles titles and 21 Grand Slam mixed doubles titles.
Wimbledon, the US, Australian and French Opens are considered the most prestigeous.
It all depends on how far they get in the tournament.
I believe Pete Sampras has won all the Slams and more than likely Bjorn Borg. Pete Sampras won 3 of the 4 majors, but never won the French Open. Bjorn Borg won 6 French Opens an 5 Wimbledons. He never won Australia or the US. The most recent players are: Andre Agassi has 4 Aus Opens, 2 US Opens, 1 Wimbledon and 1 French. Roger Federer has 6 Wimbledons, 5 US Opens, 3 Aus opens and 1 French.
im not sure what you mean by this question but tennis is played on hard court, clay court and grass court for different opens
The US Open and the Australian Open.
Through mid-2012, Maria Sharapova has won 27 World Tennis Association titles and 4 Grand Slam wins (one each at Wimbledon and in the French, US, and Australian Opens). She also has 3 trophies in WTA doubles.
