US Open: Novak Djokovic, former world number one player, will not be a part of the US Open tennis tournament starting Monday due to non-availability of Kovid-19 vaccination. This is the second time in the current season that Djokovic has not been able to play in a Grand Slam tournament due to lack of vaccination. He had earlier missed the season's first Grand Slam tournament, the Australian Open, for the same reason.

Five male players will have a chance to become the world number one during the US Open, including former world number one Rafael Nadal, who won a record 22 men's Grand Slam titles. The Spanish legend has won four titles in New York but is playing here for the first time since 2019. Spain's 36-year-old Nadal won the Australian Open in January and the French Open in June, while he also reached the Wimbledon semi-finals in July but withdrew from the tournament due to an abdominal muscle injury.

Current world number one and defending US Open champion Daniil Medvedev, Carlos Alcaraz, Stefanos Tsitsipas and Kasper Rudd need to make it to the September 11 final to top the rankings to be released the day after the US Open. .

In women's singles, Naomi Osaka has won two of her four Grand Slam titles at the US Open and is therefore considered a strong contender for the title in New York. However, she is not in good shape ahead of her first round match against Australian Open runner-up Daniel Collins on Tuesday night. Former world number one Osaka is now at number 44 and has lost her last three matches. They have won two matches and lost six since the beginning of April.

During the US Open, for the first time in a Grand Slam tournament, coaching will be allowed during the match. The coach must sit on a fixed seat near the court and can communicate with the players at the same time as they are on the same side of the court. Tenth seed Taylor Fritz, the top American player taking part in the tournament, is not too happy with the rule.
