The year 2019 will go down as a memorable one in men's tennis singles history. This year's majors witnessed Novak Djokovic stamping his authority by winning the Australian Open and Wimbledon and Rafael Nadal proving why it's never a good idea to write off a champion. The most riveting grand slam final played in 2019 was unarguably the Wimbledon final, which featured Roger Federer and Novak Djokovic. It was also the longest-ever final played in the tournament's history. Rafael Nadal winning a record 12th French Open title and ending 2019 as World No 1 Men's Singles player, courtesy of the victory at US Open 2019, made it a year to remember for the Spaniard and his fans.

Though youngsters like Daniil Medvedev, Dominic Thiem, Alexander Zverev and others impressed with their play as well as won ATP tours, it was the big two-Rafael Nadal and Novak Djokovic who ruled the Grand Slam circuit. Roger Federer came agonishingly close to a record ninth Wimbledon crown, but was beaten by the grit and determination of the Serbian great. As the year 2019 comes to an end, here's a look back at the winners of the four majors in 2019.
