Seventeen-year-old Thea Frodin just walked into Arthur Ashe Stadium to face the No. 2 seed in the world, and five years ago she was literally standing in for Serena Williams. Not metaphorically. Literally. Body double. On a movie set. If that’s not a full-circle moment, I don’t know what is.
Wait, She Was Actually in King Richard?
Yep. Back when King Richard hit theaters in 2021, Frodin worked as the body double for Demi Singleton, the actress who played a young Serena in the film. Think about that for a second – she was basically playing the physical stand-in for someone playing one of the greatest athletes of all time. That’s a weird, wonderful little Hollywood footnote that most tennis fans probably never knew existed until this week.

And now here she is, five years later, making her actual US Open singles debut. Not as a stunt double. Not on a soundstage. On the real court, against a real Grand Slam champion. I mean, come on. You couldn’t script this better if you tried (and clearly, someone kind of already did, in a roundabout way).
From Set to Center Court
Frodin told the Associated Press on Monday that she’s worked incredibly hard to get to this point, and honestly, I believe her. Getting from “background talent on a Serena Williams biopic” to “competing in the main draw of the US Open” is not a small leap. That’s years of grinding, early mornings, probably a lot of losses nobody wrote articles about. The overnight glow-up stories are almost never actually overnight.
So Who Is She Playing First? No Pressure or Anything
Rybakina. The No. 2 seed. In the first round. Look, I have to be honest here – that’s about as tough a draw as you can get for a debut. It’s not like she’s easing into the tour with a wildcard match against someone ranked outside the top 100. She’s getting thrown straight into the deep end against a Wimbledon champion with one of the scariest serves in the women’s game.
“I’ve worked so hard to try and get to this level, and to have an opportunity like this is just really special for me,” Frodin said.
That quote hits different once you know the backstory. This isn’t just a kid excited to be at a big tournament. This is someone who spent time literally standing in the shadow of a tennis legend’s on-screen story, and now she’s writing her own chapter in the same building where Serena made history over and over again.
The Part Nobody’s Talking About
Here’s the thing that’s sticking with me – Frodin’s been playing competitive tennis since childhood, with real success at the 10-and-under level. So this isn’t some fluke, feel-good, “random person gets a wildcard” story. She’s been building toward this for basically her whole life. The King Richard gig was a side note, not the main plot. But it’s the kind of detail that makes for an irresistible headline, and I get why everyone’s running with it.
Still, I think there’s a real risk of the narrative overshadowing the actual tennis. She’s 17. She’s at the US Open. That’s the story, honestly, even without the movie connection. The body double thing is a fun hook, sure, but let’s not lose sight of what she’s actually accomplished to get a singles spot in a Grand Slam main draw.
Why This Matters Beyond the Cute Coincidence
Tennis loves these narrative threads. It’s part of why the sport is so obsessively followed – you get these little connective tissue moments across generations. Serena’s story got told on film, and one of the people who helped tell it visually is now out there trying to build her own. There’s something almost poetic about it, if you’re into that kind of thing (I am, clearly, since I’m writing 1,000+ words about it).
What This Actually Means
Realistically? Rybakina is the heavy favorite here. That’s just where the numbers sit. But Grand Slam first rounds have a way of producing upsets nobody saw coming, and even if Frodin doesn’t pull it off, she’s already banked something that matters more long-term: a debut on the biggest stage in American tennis, at 17, with a story that’s going to follow her career for years.
Not every player gets a built-in narrative like this. Most just show up, play, and hope someone notices. Frodin walks in with a movie connection, a childhood résumé, and a match against a top-2 player, all before she’s even old enough to vote in a lot of states. Whatever happens Tuesday, I don’t think this is the last we hear from her – and honestly, I kind of hope it isn’t.
