On Signs Rising American Julieta Pareja to Player Roster That Includes Joao Fonseca, Ben Shelton, and Iga Swiatek

Move over, tennis world—there’s a new rising star making waves, and she’s just signed with one of the sport’s most high-powered management teams. Julieta Pareja, the teenage American talent already turning heads with her fearless game and sky-high potential, has officially joined the ON player roster—home to some of the biggest (and fastest-growing) names in the sport, including Joao Fonseca, Ben Shelton, and world No. 1 Iga Swiatek.

If you haven’t heard of Pareja yet, buckle up. The 16-year-old made a splash earlier this year with deep runs in junior tournaments and has shown the kind of poise under pressure that screams future top-10. With explosive groundstrokes, a cool on-court demeanor, and that all-American fighting spirit, Pareja isn’t just a prospect—she’s a statement. And now, with ON backing her journey, she’s got the firepower off the court to match what she brings on it.

ON, the Swiss performance brand turned tennis powerhouse, has been building an all-star roster that blends next-gen energy with elite performance. Signing Pareja signals they’re not just looking at today’s stars—they’re investing in tomorrow’s legends.

And what better environment for a young player than one that includes Iga Swiatek, a Grand Slam machine with a cerebral game, and Ben Shelton, a human highlight reel with charisma to burn? Throw in the electric Joao Fonseca, and you’ve got a dream squad of youth, talent, and momentum.

Pareja’s signing also speaks volumes about her trajectory. This isn’t just about sponsorships or gear deals—it’s about aligning with a team that believes in your long-term potential. ON’s track record speaks for itself, and the brand’s holistic approach to athlete development is the perfect fit for a player poised to break through.

So what’s next for Pareja? Expect more wildcards, more breakthrough moments, and maybe even a few upsets on the big stage. She’s got the tools, she’s got the team, and now she’s got the platform. If ON’s roster is any indication, Pareja isn’t here to play it safe—she’s here to make noise.

One thing’s clear: Julieta Pareja just got a major upgrade in the race to tennis stardom. The game better take notice.
