Happy Birthday, Kei Nishikori! From being crowned ATP Newcomer of the Year in 2008 to battling fiercely into your first Grand Slam final at the US Open in 2014—your tennis journey has been nothing short of legendary. Sure, Marin Čilić might have edged you out that day, but hey, second place still gets cake!Through every powerful forehand and lightning-fast return you've shown us what determination looks like on court. May this birthday bring fewer double faults and more aces both on and off the court. Keep swinging strong—we're all cheering for another epic run soon!
