When Morgan Riddle came across the American tennis player Taylor Fritz on Raya in the early days of lockdown, it wasn’t his athletic prowess that caught her eye. “He had a photo of him playing tennis and I was like, oh, cute,” Riddle recalls drolly over Caesar salad and oysters at Benjamin Grill inside Arthur Ashe Stadium. Instead, a photo of Fritz cradling a koala piqued her interest. While she admits that her knowledge of tennis was “nonexistent” when she and Fritz coupled up, five years later, Riddle has become a fixture in her own right in the tennis world and beyond.

Riddle and I meet during the 2025 US Open, just ahead of Fritz’s third-round match against Swiss player Jérôme Kym. (Playing on the Louis Armstrong court before him is Aryna Sabalenka, the world number one. “She might wreck this girl in like an hour,” Riddle says, eyeing the time.) She came dressed for the occasion in a sporty gray Miu Miu windbreaker dress over a pale pink button-up with matching pointy-toe stilettos. “I do not wear a flat shoe ever,” she says. (Her hard and fast rule? Orthopedic inserts.) She balances the athletic minidress with a vintage black Miu Miu bag from What Goes Around Comes Around in London, and finishes off her outfit with a healthy dose of diamonds, including a dainty anklet.

Though Riddle admits it took her six months of WAGdom to fully grasp the rules of tennis, she is locked in come game time. She sits dead center in the front row alongside Fritz’s coach and his wife, his trainer, and his mother, Kathy May. All five clutch their fists every time he earns a point, jumping to their feet when he wins a set.

As the longtime partner of the highest-ranked American tennis player in the world, Riddle is something of the first lady of American tennis. As her profile grows through her fashion and lifestyle content on YouTube, Instagram, and TikTok, she brings a whole new wave of fans into the fold. But Riddle isn’t interested in being a typical influencer.
