The BNP Paribas Open, set for October 4-17, is returning to the Southern California desert for the first time since 2019. It was delayed last year and again in March.
Djokovic is now two wins away from the first calendar-year Grand Slam in men's tennis since 1969, along with a men's-record 21st major championship overall.
Matteo Berrettini reached the third round of the Western & Southern Open with a hard-fought win over Albert Ramos-Vinolas.
"It's just the beginning. I truly believe in that," Berrettini said after he lost to Novak Djokovic at the All England Club.
The 34-year-old from Serbia is now the only man since Rod Laver in 1969 to win the first three major tournaments in a season.
The 25-year-old Italian showed great pluck to come from a break down and win the first set before the Serb gathered himself and won 6-7 (4/7), 6-4, 6-4, 6-3 for a record equalling 20th Grand Slam.
The 34-year-old Serb had shown all his battling qualities and mental strength to come from a set down and beat Matteo Berrettini 6-7 (4/7), 6-4, 6-4, 6-3 for sixth Wimbledon crown on Sunday.
Djokovic won his first Wimbledon title in 2011, dethroning champion Rafael Nadal to celebrate his coronation as new world number one in style.
The world number one triumphed 6-7 (4/7), 6-4, 6-4, 6-3 over battling Matteo Berrettini to move level on 20 majors with Roger Federer and Rafael Nadal.
Djokovic recalled what it felt like to participate in a Slam final for the first time. He was 20 and lost to Roger Federer in three tight sets, including two tiebreakers, at the 2007 U.S. Open.
Berrettini claimed a 6-3, 6-0, 6-7 (3/7), 6-4 win over his Polish opponent Hubert Hurkacz, who had knocked out eight-time champion Roger Federer in the quarter-finals.
The world number one will be playing in his seventh final at the All England Club and 30th at the majors.
Berrettini admits he is far more stressed when he watches girlfriend Ajla Tomljanovic's matches -- "my hands become very sweaty" -- than when he is immersed in his own.
He will also just need the US Open to become only the third man in history, and first since 1969, to complete the calendar Grand Slam.
The 25-year-old Italian will play Hubert Hurkacz on Friday for a place in the Wimbledon final after the Pole stunned eight-time champion Roger Federer in straight sets.
