US Open Will Offer 'Quiet Rooms' and Provide More Mental Health Resources: 'It Is Essential' Tim Clayton/Corbis via Getty Who Will Headline While major stars, including Serena Williams, Venus Williams, Roger Federer, and Rafael Nadal have all pulled from the event due to injuries, the tournament will still see some big names. All eyes will be on Novak Djokovic, a favorite to secure a win in the men's singles tournament and could make history by winning every major in a calendar year. If successful, Djokovic would become the first singles player to reach the milestone since Steffi Graf in 1988. The Serbian tennis star is also hoping to pass Federer and Nadal for the most Grand Slam singles titles in men's history. Also in the tournament is Naomi Osaka, who hopes to defend her title and win her third US Open. This comes after the 23-year-old pulled out from the French Open and Wimbledon amid her struggles with depression. After Osaka brought conversations about mental health to the forefront, the USTA announced that the tournament will now have increased mental health resources, such as licensed mental health providers and quiet rooms.

This year, all attendees age 12 and older will have to show proof of at least one dose of the COVID vaccine to enter. Face masks will also be required for guests indoors following Mayor Bill de Blasio's ruling that Arthur Ashe Stadium is an indoor venue when its roof is in place. "Today, the USTA was informed that the New York City mayor's office will be mandating proof of COVID-19 vaccination for entrance to Arthur Ashe Stadium," an announcement shared last Friday read. "Given the continuing evolution of the Delta variant and in keeping with our intention to put the health and safety of our fans first, the USTA will extend the mayor's requirement to all US Open ticket holders 12 years old and older."
