At 20 years old, Oihan Guillamoundeguy arrives in Mallorca with his homework done. He is fifth in the Road to Mallorca —the HotelPlanner Tour ranking— and has secured his card for the DP World Tour 2026. He is, after Joshua Berry, the second youngest player in this Final, but speaks with the maturity of someone who has already lived more than it seems.
The young man from Soorts-Hossegor, in the southwest of France, feels calm after the second day in Alcanada, despite being at PAR for the course and beyond the 30th position. He looks at the sea and smiles. What lies behind that smile, however, is a story that could have ended very differently.
Because Oihan was not meant to be a golfer. He was meant to be a pilot. “My dream was to be a motocross rider,” he says. He started at the age of five, almost before learning to write. His childhood was spent among dirt jumps, roaring engines, and pure speed. Two of his best friends, he says, are still dedicated to that. “I love speed, adrenaline… but it’s very dangerous.”
In his case, the danger was literal. At eight years old, a check-up changed his life. He was diagnosed with a serious heart anomaly, a congenital defect that prevented blood from flowing properly through his heart. “They told me I could die,” he recalls with contained coldness. Shortly after, at twelve, the operation came: heart valve replacement. “It was a very difficult time.”
He had to leave the bikes. From one day to the next, the boy who dreamed of being a pilot was left without an engine. “At first I didn’t like golf,” he confesses. “It was very different, too quiet. Little by little I started playing very well… and I got hooked.”
That life-enforced change became a second chance. Oihan smiles as he remembers it: “Life is very short, you have to enjoy it. Don’t complain, there are tough moments.” He doesn’t say it as a learned phrase; he says it as someone who has felt it.
Today, that life perspective is evident in his way of competing. He plays fearlessly, as if each round were a gift. His style is aggressive, creative, and very passionate. There is a significant family detail, his caddie is his brother: “I owe him a lot. He is part of this success,” acknowledges the Frenchman.
Guillamoundeguy is part of an excellent French generation. In the last four years, thirteen French players have moved up to the DP World Tour, a figure that speaks of the current strength of French golf. Oihan feels proud to belong to that group and to share the journey with two very close friends: Tom Vaillant and Martin Couvra. They are the three musketeers. There are two years of difference between them, and interestingly, each has moved up in a different season: Vaillant in 2023, Couvra in 2024, and he in 2025. “We talk a lot, we support each other. It’s nice to see that we are all fulfilling our dreams.”
His idol, however, is outside France. Rory McIlroy. He doesn’t hesitate for a second when mentioning him. “I’ve always liked his way of playing, his attitude. He is aggressive, natural, and enjoys what he does.” Perhaps he sees himself reflected in that: in that mix of talent, joy, and inner fire.
Oihan is still a 20-year-old boy, but his story already has more layers than many veterans. In just three years he has gone from debuting and winning as an amateur in the Alps Tour to also winning in the HotelPlanner Tour and securing a place among the best on the continent.
Motocross taught him vertigo and golf taught him patience. From the combination of both things, this new French musketeer has emerged, a player with the soul of a pilot and a heart of iron. In Mallorca, with the card in his pocket, Oihan Guillamoundeguy seems ready for his next leap, this time, without an engine.
