Early Career
Karue Sell’s tennis journey began in the coastal city of Jaraguá do Sul, Brazil, where he first picked up a racket at age six.
By 12, he was dominating regional tournaments, catching the eye of coaches with his explosive two-handed backhand and tactical maturity. His breakthrough came in 2009 when, at 15, he became Brazil’s top junior player and earned wildcards into Junior Grand Slam events.
At the 2011 Australian Open Juniors, he stunned crowds by reaching the doubles semifinals alongside American partner Mitchell Krueger, a run that showcased his net skills and chemistry with diverse playing styles. The pressure of early success took its toll.
After struggling with injuries and burnout, Sell stepped back from competitive tennis in 2011, later describing this period as “losing the joy in the grind.” He moved to Los Angeles in 2013 to study geography at UCLA, where he balanced academics with Division I tennis.
As team captain (2015–2016), he led the Bruins to back-to-back NCAA quarterfinals while developing a reputation for analyzing opponents’ weaknesses—a skill that later defined his YouTube tutorials. During his 2011–2017 hiatus from pro tours, Sell quietly honed his craft through unconventional channels.
He coached junior players at Beverly Hills Tennis Club, worked as a hitting partner for WTA stars like Sofia Kenin, and famously helped Naomi Osaka refine her footwork ahead of her 2020 US Open victory.
Professional Career
Karue Sell’s pro journey is a rollercoaster of comebacks, viral moments, and relentless hustle. After turning pro in 2009, he initially struggled with burnout, stepping away from the sport in 2011 to focus on college tennis at UCLA. As a Bruin (2013–2016), he became a cornerstone of the team, racking up a 104–31 singles record and leading UCLA to NCAA semifinal appearances.
His 2016 season saw him earn All-Pac-12 honors while mentoring future stars like Marcos Giron. Sell’s first pro resurgence came in 2017 when he claimed his maiden ITF Futures title in Claremont, California, edging out UCLA teammate Martin Redlicki in a nail-biting three-set final.
By 2018, he’d climbed to a career-high ATP ranking of No. 371 after back-to-back Futures wins in Los Angeles and Little Rock. Yet financial strain and injuries forced another hiatus in 2019, during which he pivoted to coaching—most notably shaping Naomi Osaka’s footwork ahead of her 2020 US Open triumph.
The Brazilian’s 2023 comeback defied expectations. At 30, he won the M15 Morelia title in Mexico and reignited his passion through his YouTube series Turning Pro at 30, blending match analysis with gritty travel vlogs. His 2024 Bogotá Challenger semifinal run—toppling top-300 players like Juan Pablo Ficovich—propelled him into the ATP top 300 for the first time.
Though he fell short against Facundo Mena in a decisive third-set collapse, his tweet—“ bad for a 30-year-old YouTuber”—racked up 50,000+ likes, cementing his status as tennis’ unlikeliest influencer. Now balancing tournaments with brand deals (Wilson, Babolat, MprooV), Sell’s 2025 schedule mixes Challenger events and content creation.
His $3,000–$5,000 monthly YouTube revenue funds training, while sponsors cover gear and recovery tools. With a 56–20 record since 2023 and eyes on Australian Open qualifying, Sell proves that in the digital age, a pro career isn’t just about rankings—it’s about building a brand that outlasts the scoreboard.
