Having traded the Southern California sun for the bright afternoon glare of Flushing Meadows, Thea Frodin proved on Tuesday that her game belongs on tennis’s grandest stage, regardless of what the final score said.

The Woodland Hills native fell 6-3, 6-2 to No. 2 seed and 2026 Australian Open champion Elena Rybakina at the USTA Billie Jean King National Tennis Center, bringing an end to her first Grand Slam main draw appearance. As the second-youngest player in this year’s edition of the tournament at just 17 years old, Frodin was tested against one of the best players in the world—who entered the US Open with an opportunity to claim the No. 1 ranking from Aryna Sabalenka. Yet she showcased the raw power, fearless composure, and competitive spirit that have made her one of the most promising young players in American tennis.

“Obviously I had a tough first round. Rybakina is a great player,” Frodin said after the match. “My goal on court is always to have an aggressive game style. Today it was a bit harder to bring that out, because she is a very aggressive player. It was a fun experience to see how the best players in the world hit their balls and their shots. Hopefully the next time I meet her, if I do, I can be more experienced and see what I can do.”

She also gave the Grandstand crowd plenty to cheer about.

Frodin fired 11 aces, nearly doubling the total of her world class opponent and one of the WTA’s most dangerous servers. Trailing 5-1 in the second set, the teenager refused to go quietly. With the Grandstand crowd chanting her name, Frodin saved match point with an ace, then followed with another to fend off a second opportunity before holding serve. Rybakina eventually closed out the match on her fourth match point, but not before Frodin had finished with 19 winners and given the crowd one final glimpse of her fight and resilience.

“She has great shots, and especially serve,” Rybakina said following their match. “She has this powerful game, which is I think great, and it’s just a matter of experience, being more stable, playing matches. But she has the game. She can be quite dangerous with these kind of shots.”

Coming from the world No. 2 player, the assessment was a fitting reflection of what Frodin showed in her Grand Slam debut.

That relentless, aggressive baseline game isn’t an accident; it’s quintessential Southern California tennis. Frodin’s rapid rise came into full view just weeks ago at Barnes Tennis Center in San Diego, where she conquered the country’s top junior field at the USTA Billie Jean King Girls’ 18s National Championships. That victory earned her a wild card into the final Grand Slam of the season, transforming the high school student into a Grand Slam main draw competitor overnight. A year earlier, she had a glimpse of the spotlight after winning the Girls’ 18s doubles title and earning a US Open women’s doubles wild card.

That Hollywood-caliber ascension is fitting for a player who, five years ago, served as a body double for a young Serena Williams—another legendary Southern Californian who honed her iconic game on the public courts of Compton—in the Oscar-winning film King Richard. Frodin spent six months copying the 23-time Grand Slam champion’s swing so closely that her parents briefly worried when she struggled to revert back to her own technique after filming wrapped.

On Tuesday in New York, there was no movie set or role to play. Frodin was writing her own chapter on the very grounds where her idol built a legacy, though her cinematic history didn’t go unnoticed.

“Some of my team told me, because they were doing the research,” Rybakina admitted with a smile. “I didn’t see the movie, but I think it’s a cool experience, definitely.”

Even with global media attention and a social media shoutout from actor and former co-star Will Smith, the SoCal native remains grounded.

“It’s hard to get away from all of that,” Frodin said. “It’s just about accepting it and not letting it get to you. I saw that Will Smith reposted one of my posts, so that was pretty cool, but I didn’t let any of it get to me.”

Frodin is not rushing to decide what comes next, whether that means pursuing NCAA tennis and taking advantage of name, image, and likeness opportunities, skipping college to turn professional, or even entertaining future acting roles as a side gig alongside her main focus on the court. For now, she is focused on finishing high school and continuing to develop her game while giving herself time to figure out the path that is right for her.

“Yeah, I mean, I think I’m trying to just finish high school, see where the rest of this year takes me,” she said. “I’m not rushing into kind of making a decision with all that.”

Her New York stay isn’t over, either. Frodin will stay in Flushing Meadows to compete in the US Open Junior Championships beginning September 6, her final event as an eligible junior. A year ago, she reached the quarterfinals of the junior girls’ singles draw, and she will look to cap her junior career with another memorable run.

Tuesday showed that while the gap between top juniors and established pros is real, Frodin has the tools, mindset, and poise to close it. The girl who once dreamed of competing on this stage has officially arrived, and next time, she’ll know exactly what to expect, and she’ll be coming for more.
