It is well known how dominant this generation is at the Grand Slams on all surfaces. Consider from 1970 to 2004, only one player (Ivan Lendl in 1987) reached the semifinals of all 4 Grand Slams in one year. Incredibly, since 2004, Federer reached the semifinals of all 4 Grand Slams in on year in 2005, 2006, 2007, 2008, and 2009. Nadal in 2008. Now in 2011, Andy Murray and Novak Djokovic can both achieve this at the 2011 U.S. Open.
