The 2021 ATP Season saw Novak Djokovic once again dominate at the grand slams, winning 3 out of 4 including the Australian Open, French Open, and Wimbledon Titles.
His loss to Daniil Medvedev in the US Open Final deprived Djokovic of achieving a calendar grand slam.
It was a bit more competitive in the Masters 1000 tournaments in 2021 with 8 different players winning a Masters 1000 title.
Other notable ATP Tournament Winners in 2021 include Alexander Zverev’s gold medal at the 2020 Tokyo Olympics and Daniil Medvedev’s first grand slam title win at the US Open.
In terms of 2021 team events, it was a very good year for Russia with them claiming the ATP Cup in January and the Davis Cup in November.
Team Europe won their fourth Laver Cup in a row with a comprehensive 14-1 win over Team World in Boston.
