Alex Eala has yet to hit her first ball at the 2026 US Open, but the Filipina tennis sensation may have already scored one of the tournament’s most surprising wins.
And it didn’t happen on a tennis court.
Eala’s US Open Nike outfit reportedly sold out ahead of the gear associated with some of the sport’s biggest superstars — a remarkable sign of just how powerful the 21-year-old’s growing fanbase has become.
According to Hard Court’s Jessica Schiffer, Eala’s Nike look for the season’s final Grand Slam disappeared from shelves almost immediately, while apparel linked to other prominent Nike tennis stars remained available.
Those names reportedly include Carlos Alcaraz, Jannik Sinner and Aryna Sabalenka.
If there were still doubts about Eala’s ability to attract attention beyond her results, this may be the clearest answer yet.
The ‘Alex Eala effect’ is getting harder to ignore
For Filipino tennis fans, Eala’s massive following is hardly a surprise.
Philippine flags have become an increasingly familiar sight wherever she competes. From Australia and Dubai to Rome, London, Washington and Toronto, Filipino supporters have repeatedly transformed overseas tournaments into something resembling a home crowd.
The chants of “Let’s go, Alex!” have followed her around the world.
Now, that enthusiasm appears to be spilling beyond stadium seats and onto store shelves.
Eala has previously acknowledged that she understands the significance of being the first Filipina to reach heights previously unseen in Philippine tennis.
“I think with the platform that I have, it’s important for me to be aware of the impact that I hold also,” Eala said after receiving another huge show of support in Washington.
“I understand that I represent a lot. I represent a minority.”
Even her rivals have noticed.
Jasmine Paolini has spoken positively about the excitement surrounding Eala, while American star Jessica Pegula admitted she was surprised by how much the Filipina’s following had grown since they first crossed paths in Miami.
But selling out merchandise before some of tennis’ most recognizable names takes the phenomenon to another level.
From breakout star to marketing force
Eala was already a household name among Filipino sports fans when her stunning run to the Miami Open semifinals in 2025 introduced her to a much broader international audience.
What followed was not merely a temporary surge of attention.
Eala continued climbing.
Earlier this month, she captured her first WTA Tour singles championship in Washington, becoming the first Filipina to win a tour-level singles crown.
And she certainly did not take an easy road to the trophy.
Her title run featured victories over a star-studded group that included Zheng Qinwen, Leylah Fernandez, Elina Svitolina, Naomi Osaka and Pegula.
The breakthrough propelled Eala into the world’s Top 20 for the first time.
She followed that achievement with another solid campaign in Toronto, defeating Alycia Parks and Caty McNally before falling to Belinda Bencic in the fourth round.
At Cincinnati, Eala again showed she could compete with elite opposition, taking the opening set against Amanda Anisimova before eventually bowing out, 4-6, 6-4, 6-2.
The results have established Eala as much more than a feel-good story from a country without a long tradition of producing top-level tennis stars.
She’s now becoming a genuine attraction.
New York could make the Eala phenomenon even bigger
That makes the US Open particularly intriguing.
Eala won’t be appearing in New York in just one event.
She is set to compete in the women’s singles draw and will partner Canadian star Felix Auger-Aliassime in mixed doubles. She is also scheduled to appear at the Stars of the Open exhibition.
That means plenty of opportunities for Eala — and that suddenly hard-to-find Nike outfit — to appear before one of tennis’ biggest global audiences.
New York also holds special meaning for the Filipina.
It was at Flushing Meadows in 2022 where Eala won the US Open girls’ singles championship, providing an early glimpse of the player she could eventually become.
Four years later, she returns in dramatically different circumstances.
She is no longer merely the promising junior carrying Philippine hopes.
She arrives as a WTA champion, a Top 20 player and one of the most passionately supported young stars on the women’s tour.
And apparently, fans aren’t waiting for her first-round match to show their support.
They’ve already been shopping.
Eala has repeatedly made clear that reaching one milestone only makes her hungry for another.
“It’s like, ‘Wow, I achieved that. Okay, let’s go for more,’” she said following her Washington breakthrough.
The US Open women’s singles main draw begins August 30.
But if merchandise sales are any indication, the Alex Eala show in New York may have already started.
