While the tennis at the 2026 Madrid Open has been top-notch, a different kind of star has emerged from the Caja Mágica—one who's turning heads without even picking up a racket. Lucía Sastrón, a model working as a ball girl, has gone viral for her stunning looks and undeniable presence on the court.
Fans couldn't help but notice Sastrón during the early rounds of the Masters 1000 event, and social media quickly lit up with posts praising her appearance. "My favorite part of Madrid Open this year," one user wrote on X, formerly known as Twitter. Another chimed in, "The 'ball kids' in Madrid are literally models." The buzz even extended to her Instagram, where one commenter asked, "Did I really get the Instagram of the girl I see on TV at the tennis tournament?"
Sastrón, who boasts over 17,500 Instagram followers, isn't new to the spotlight. Before the Madrid Open, she had already made waves as a model, but this week has catapulted her into a new level of fame. Her viral moment adds a unique twist to the tournament, proving that sometimes the action off the court can be just as captivating as the matches themselves.
Speaking of matches, the women's final is set for Saturday, featuring Mirra Andreeva and Marta Kostyuk. Andreeva, who nearly stumbled against Anna Bondar in the Round of 16, has since been on fire, dropping zero sets against Leylah Fernandez and Hailey Baptiste. Kostyuk, meanwhile, has lost only one set throughout the tournament. Tennis fans are also keeping an eye on Coco Gauff's recent comments about bettors after her early exit.
On the men's side, Jannik Sinner is the heavy favorite to claim his third consecutive tournament title. The Italian star has been dominant, and his girlfriend Laila Hasanovic has also been turning heads off the court. Meanwhile, other stars like Anastasia Potapova have been making fashion statements of their own.
The Madrid Open wraps up this weekend, with the women's final kicking off at 11 a.m. ET on Saturday. Whether you're tuning in for the tennis or the unexpected viral moments, this year's edition has delivered plenty of drama. As for Sastrón, she's already won over the internet—and maybe a few new fans who'll be watching the ball kids a little more closely.
