US Open: Why is it so difficult to win a second grand slam?
CNN
When Emma Raducanu won the US Open last year, she dropped her racket, sank to the floor and covered her face in her hands.
It was a familiar scene, one repeated throughout the years by first-time grand slam winners; Daniil Medvedev also fell to the floor as he won his maiden grand slam a day after Raducanu, as did Dominic Thiem a year before that.
Even 23-time grand slam winner Serena Williams, who will "evolve away from tennis" after this tournament, seemed shocked when she won her first at the 1999 US Open.
