# 2021 Novak Djokovic tennis season

The 2021 Novak Djokovic tennis season is considered one of Djokovic's best. It saw him become the second man in tennis history to achieve the Surface Slam (winning majors on the three different surfaces of clay, grass and hard court in the same calendar year) following Rafael Nadal in 2010, and repeat his feat from 2015 of reaching all four major finals in a season. He won five tournaments, three of them majors: the Australian Open, the French Open, and the Wimbledon Championships. Djokovic reached the final of the US Open in an attempt to achieve the Grand Slam, but finished runner-up to Daniil Medvedev. He also won the Paris Masters and Belgrade Open, and reached his first final in a doubles tournament since 2010 at the Mallorca Open.
During this season, Djokovic:
* Surpassed Roger Federer's record number of 310 weeks spent with the ATP No. 1 singles ranking to 353.
* Surpassed Pete Sampras' record of six year-end No. 1 ranking finishes to seven.
* Surpassed his record (joint with Nadal) of 36 Masters 1000 titles to 37.
* Surpassed Federer's record of 224 wins over top 10 players to 229.
* Tied Federer and Nadal's all-time record total of 20 men's singles major titles.
* Tied Federer's all-time record of 31 major finals reached.
* Tied Federer's all-time record of 13 Olympic singles victories.

## Yearly summary
### ATP Cup

Novak Djokovic began his official season by taking part in Serbia's national team in the ATP Cup. Looking to defend the past year's title, Serbia met Canada and Germany in Group A. Djokovic defeated Denis Shapovalov in straight sets, and teamed with Filip Krajinović to defeat Shapovalov and Milos Raonic in doubles, to help Serbia defeat Canada. However, Serbia's tournament ended with a loss against Germany. Djokovic defeated Alexander Zverev in three sets, but lost in doubles with Nikola Ćaćić against Zverev and Jan-Lennard Struff.

### Australian Open

Djokovic started the Australian open with a straight sets win against Jérémy Chardy and a four-set win against Frances Tiafoe. Djokovic won a five-set thriller against Taylor Fritz in the third round, despite an injury scare. He continued his dominance at the Australian Open by overwhelming Milos Raonic and Zverev in four sets. He defeated Russians Aslan Karatsev and Daniil Medvedev in straight sets in the semi-finals and finals, to win the Australian Open again. The victory marked his record-extending ninth men's singles title at the tournament, and also his 18th major title overall.

### Miami Open

Djokovic withdrew from the 2021 Miami Open, citing a desire to rest after the Australian Open and spend more time with family. He also wanted to prepare for the upcoming clay court season.

### Spring clay court season
#### Monte-Carlo Masters

After a straight sets win over Sinner, Djokovic was upset by Dan Evans in the third round, marking his first singles loss of the season.

#### Serbia Open

After straight-sets wins over Kwon Soon-woo and compatriot Miomir Kecmanović, Djokovic lost in the semifinals to Karatsev in three tight sets.

#### Italian Open

Djokovic started the defense of his Italian Open title with straight sets wins over Fritz and Alejandro Davidovich Fokina. After this, he had an early scare, down a set and a break in a rainy match against Stefanos Tsitsipas that was postponed. The next day, he made a comeback and won. The same day, he also won his semifinal against Lorenzo Sonego in three sets. Djokovic then lost to Rafael Nadal in the final in three sets.

#### Serbia Open Part 2

Djokovic started the Serbia Open part 2 with straight sets wins over Mats Moraing and Federico Coria. After reaching the final with a three set win over Andrej Martin, Djokovic won his 83rd title, at home, defeating Alex Molčan in straight sets.

#### French Open

Djokovic began with straight set wins against Tennys Sandgren, Pablo Cuevas, and Ričardas Berankis in the first three rounds. In the fourth round, Lorenzo Musetti led by two sets to love, but Djokovic then won all but one game afterwards; Musetti retired in the fifth set. After a four set win in the quarterfinals against Matteo Berrettini, Djokovic shockingly defeated Nadal in the semifinals in four brutal sets, only the second time he had beaten Nadal at Roland Garros, and only the third time Nadal lost at the event. Djokovic then defeated Stefanos Tsitsipas in the final in five sets, after losing the first two. It was his 19th major title, and he completed a double Career Grand Slam. He became the first player in the Open Era to win a Major after coming back from a two-set deficit in two separate matches in the same tournament (in the fourth round and the final). He also became the first player to beat Nadal on the way to winning Roland Garros.

### Grass court season
#### Mallorca Open

Djokovic's grass-court season began at the Mallorca Championships, where he competed in doubles alongside Carlos Gómez-Herrera. The team advanced to the final, but they withdrew before the match due to an injury to Gómez-Herrera.

#### Wimbledon

Djokovic entered Wimbledon as the defending champion from 2019 and the favorite for the title. He won a four-set first round over British wildcard Jack Draper. He reached the final with five straight set wins, defeating Denis Kudla, former runner-up Kevin Anderson, Márton Fucsovics, Chilean seed Cristian Garín, and Denis Shapovalov. He then recovered from a one-set deficit in the final against Matteo Berrettini to claim his sixth Wimbledon title and 20th men's singles major title overall, equaling Roger Federer and Nadal's all-time record.

### Late hard court season
#### Tokyo Olympics

Djokovic opened his summer hard court season at the Tokyo Olympics, where he sought to improve on his bronze medal result from Beijing 2008 and pursue a potential calendar-year and career Golden Slam. He won his first four rounds in straight sets, against Hugo Dellien Struff, Davidovich Fokina and hometown player Kei Nishikori, to reach the semifinals, where he lost to Alexander Zverev in 3 sets despite being a set and a break up. He then lost his bronze medal match to Pablo Carreño Busta in 3 tight sets. He also participated in the mixed doubles alongside Nina Stojanović, where the pair won their first two matches in straight sets but lost in the semifinals and withdrew from the bronze medal match. Djokovic thus left the Olympics without any medals.

#### US Open

Djokovic entered the tournament in contention for the Grand Slam, a feat in men's singles tennis achieved only by Don Budge in 1938 and Rod Laver in 1962 and 1969. Djokovic won in four sets against Holger Rune and against Tallon Griekspoor in straight sets. He then proceeded to lose the first set and win the subsequent three in each of his next three matches, against Nishikori, Jenson Brooksby, and Berrettini. He then defeated Zverev in five sets in the semifinals. Djokovic then lost in the final to Medvedev in straight sets, ending his Grand Slam bid.

### European indoor hard court season
#### Paris Masters

Djokovic played in men's doubles, partnering Krajinovic. They won in the first round, but lost the next round in straight sets. In singles, Djokovic defeated Márton Fucsovics in 3 sets, and advanced to the quarter-finals after a walkover by Gaël Monfils in the Round of 16. He won the semifinals against Hubert Hurkacz in three sets in the semifinals, securing the year-end No. 1 ranking for a record seventh time. In the final, he avenged his US Open final loss by beating Medvedev in three sets, winning a record-extending sixth Paris Masters title, and a record 37th Masters title overall.

#### ATP Finals

Djokovic won all of his round-robin matches (against Casper Ruud, Andrey Rublev, and Cameron Norrie) in straight sets to advance to the semifinals, but then lost a 3-setter to Alexander Zverev.
