Outside the grandstand, while she idled beneath the summer sun, a passer-by stopped, turned and pointed a phone at her, then wordlessly walked away. Ms. Riddle just adjusted her black oval Carolyn Bessette-Kennedy-style sunglasses.
Once inside the tennis match, while she and more than 1,000 other spectators found their seats, people were more direct. “Are you Morgan?” “I recognize you!” “Can we get a photo?” She said yes at least a dozen times that afternoon.
“You’re so tiny!” said Sue McDonald, who had come to the National Bank Open in Toronto with her 19-year-old daughter, Jaiden. She had never been able to get her children interested in the sport, Ms. McDonald told Ms. Riddle, until last summer, when one player on TV caught her daughter’s eye.
“I’m sitting there watching Wimbledon, and I’m like, ‘Come and see this guy,’” she said. “‘Come and see this tall, dark, handsome guy.’ She comes walking in, and she’s like, ‘Oh, who’s this?’”
It was Taylor Fritz, a player from Southern California recognizable for his height (a lean 6-foot-5) and his center-parted, cartoon-prince waves, which he restrains during matches with a Nike headband. Mr. Fritz, 25, is the top American player in men’s tennis, currently ranked ninth in the world.
But he wasn’t the only person the McDonalds were watching during that match.
Every so often, the screen flashed to a young woman wearing a crisp white dress and gold jewelry with blond tendrils framing her face, sitting ultra-poised in the player’s box with Mr.
Fritz’s team of coaches and supporters. They looked her up online and soon began following Ms. Riddle on social media, where she shares her life as a tennis WAG — an acronym for “wives and girlfriends,” popularized in Britain in the mid-2000s to describe, disparagingly, a group of preening, partying women attached to soccer players.
Ms. Riddle, 26, doesn’t mind the acronym, she said. She also doesn’t mind being called an influencer, a similarly stigmatized title.
She has thick skin and a cleareyed confidence in the life she’s building while accompanying her boyfriend around the world for some 35 weeks each year.
What began in early 2022 with her trying on outfits for the Australian Open on TikTok (a video that has since been viewed 1.5 million times) has evolved into her being hired by Wimbledon to host
“Wimbledon Threads,” a video series on fashion at the tournament. This summer, she released two pieces of gold-plated jewelry — a bracelet ($125) and necklace ($175), each with a tennis-racket charm — in collaboration with a small New York jewelry company called Lottie.
