At just 18 years old, Gabriella "Gabby Golf Girl" DeGasperis is proving she's more than just a viral sensation. She's the young gun who beat NBA superstar Steph Curry in a head-to-head match—and now she's reshaping the game of golf on YouTube, blending competition, storytelling, and everyday players to build a media empire that's catching fire.

It was a moment that stunned even the most seasoned golf fans. During a one-on-one match with the four-time NBA champion—who's also a champion at the American Century Championship—DeGasperis split the fairway with a massive drive, earning a rare ovation from Curry himself. The match ended tied after regulation, but DeGasperis sealed the win in a chip-off playoff. "I hadn't been nervous in a while—honestly the only times I've felt that were playing with Jon Rahm and with Steph Curry," she said. "I didn't think I was going to win, but as it went on I realized, 'wait, I can actually win here,' and that was incredible."

Winning has quickly become her norm. Known online as "Gabby Golf Girl," DeGasperis has amassed nearly two million followers across Facebook, YouTube, Instagram, and TikTok. Based in West Palm Beach, Florida, she's one of the fastest-growing creators in the sport. Her journey started early: she first picked up a golf club at age two, after receiving a set of pink clubs for her birthday, and soon began competing in junior tournaments.

But her rise to fame wasn't just about skill. She began posting regularly ahead of her freshman year of high school, using social media as an outlet to cope with social isolation and bullying. When one of her early Instagram reels hit 20,000 views, she realized her hobby could become a business. Now, at 18, she's gone far beyond trick-shot clips—like the one where she scoops up a ball, flips it over her shoulder, and watches it drop in the cup as she walks away.

Gabby has developed a recognizable on-course identity, complete with a signature tee-box routine: a shoulder tap, twist, and extension sequence before the follow-through. It's a simple, repeatable checklist that breaks down classic swing fundamentals—and it resonates with golfers of all levels. Whether she's competing against pros or inspiring beginners, Gabby Golf Girl is pioneering a new format for the game, one viral moment at a time.
