Morgan Riddle, a 27-year-old fashion influencer with nearly 600,000 TikTok followers, has become a visible presence at Wimbledon as she supports boyfriend Taylor Fritz, the first American man to reach the tournament’s semifinals since 2022. Riddle has collaborated with the All England Club on “Wimbledon Threads” videos explaining trends such as “tenniscore” and has been profiled in Vogue, Harper’s Bazaar and the New York Times Style section. Fritz, the 2024 U.S. Open runner-up and now a Wimbledon semifinalist, credited Riddle for helping sharpen his focus. “There’s an obvious correlation between my results and ranking and the time we’ve been together,” the world No. 4 said after his 6-3, 6-4, 1-6, 7-6 (4) quarter-final win over Russia’s Karen Khachanov. The couple, who met five years ago, also appeared in the Netflix documentary “Break Point.” Riddle’s social-media coverage and courtside fashion have drawn attention beyond sport, illustrating how Wimbledon is increasingly doubling as a global style showcase. Her growing profile—and Fritz’s deep run—highlight tennis’s crossover appeal to audiences interested in both athletics and lifestyle branding.
