World No. 1 Novak Djokovic failed in his quest to become the first man since Rod Laver in 1969 to win a Calendar Slam as the reigning Wimbledon champion put up a listless display against second-seeded Daniil Medvedev in the US Open final. The Serbian lost the match 6-4, 6-4, 6-4 in two hours and 15 minutes in New York on Sunday.
