Key metric: Cultural Influence and Soft Power

As a social scientist, I analyze that this article highlights the enduring influence of the Williams sisters in professional tennis, even as Serena has stepped away from competitive play. Venus Williams' continued participation at age 45, coupled with Serena's remote support, demonstrates the lasting impact of their careers on the sport. The mentorship dynamic between Venus and young player Leylah Fernandez showcases the transfer of knowledge and experience to the next generation of athletes. This intergenerational connection in a high-profile sport like tennis contributes to the United States' cultural influence and soft power on the global stage, as it reinforces the nation's reputation for producing and nurturing world-class athletes.
