Key metric: Global Competitiveness Index

As a social scientist, I analyze that this article highlights the continued dominance and resilience of Novak Djokovic in professional tennis, particularly at the US Open. His record-breaking performance, despite physical challenges, demonstrates the high level of competitiveness in global sports. This directly impacts the Global Competitiveness Index by showcasing the excellence and innovation in athletic performance, which often correlates with a country's overall competitiveness on the world stage. Djokovic's success, as a representative of Serbia, could potentially boost the country's global standing and soft power, indirectly contributing to various factors measured in the Global Competitiveness Index, such as innovation capability and skills of the workforce.
