Sometimes you are in the right place as a player and if you are fortunate as a spectator.
This morning (Australia EST) I had the great good fortune to see live Roger Federer‘s shot (6-5 third set, 30-0) to take his US Open semi-final to match point. He described his shot in the immediate after game interview as his greatest shot ever. (See AFP story here with image, and an early example on YouTube.)
What was wonderful about the shot in real-time was that it looked possible. He created time to execute a shot practiced many times in training. I think it will become an iconic moment in tennis history and the slow motion replays of the stroke have some great spontaneous moments of recognition. Novak Djokovic, the crowd and Roger Federer have wonderful reactions.
These moments leave you happy that you were around and for coaches and athletes offer new possibilities.
