Swiss sportswear brand On, endorsed by tennis legend Roger Federer, is expanding its roster of young tennis prodigies. Following the signing of 17-year-old João Fonseca and 20-year-old Ben Shelton, On has now welcomed 15-year-old German Julia Stusek to its WTA contingent, alongside world number one Iga Swiatek.Stusek made her WTA main-draw debut at the Bad Homburg Open as a lucky loser, showcasing her potential in a competitive 6-2, 7-5 loss to American Peyton Stearns. Her appearance marked the first time she wore On's signature tank and skirt, similar to the attire Swiatek wore during her recent Roland Garros triumph.While Swiatek and Shelton represent On's current tennis presence, Fonseca and Stusek embody the brand's investment in the future. Fonseca, the 2023 junior US Open champion, turned professional this year and has already made history as the first ATP player born in 2006 to win a main-draw match. He also reached the quarterfinals in Rio de Janeiro and won a round at the Madrid Masters 1000.Stusek, on the other hand, is regarded as one of Germany's most promising young talents. At just 13 years old, she won the prestigious Les Petit As title in 2022 and reached the junior Australian Open doubles final this year."I couldn't be more thrilled to become a part of the On team," Stusek expressed on Instagram. "I'm excited to represent this unique, young, and creative brand on and off the tennis court."On's recent signing of Zendaya as a brand ambassador suggests that the brand may be planning to feature these talented teens in future campaigns alongside the likes of Tashi Duncan.
