Jannik Sinner triumphed at the 2024 US Open, defeating Taylor Fritz in straight sets to secure his second Grand Slam title of the year, becoming the first Italian man to win the US Open. This victory also marked the end of a 21-year drought for American men in Grand Slam tournaments. Sinner's background as a competitive skier has been credited for developing his mental focus and aggressive playing style in tennis. Meanwhile, Olympic track star Noah Lyles attended the US Open and asserted that the tournament's champions, including Sinner and women's finalists Aryna Sabalenka and Jessica Pegula, are 'World Champions' due to their international competition. This comment sparked discussions about the legitimacy of the title 'World Champion' in various sports contexts, particularly in relation to the NBA. Lyles emphasized that tennis players consistently face top competitors globally, justifying their claim to the title.
