Mario Saint-Supery Returns to Valencia: Young Gonzaga Star Chooses EuroLeague Over College

Point Guard - After just one season at Gonzaga, where he was named All-WCC as a freshman, Mario Saint-Supery has signed a long-term deal with Valencia Basket. "El Principito" heads back to Spain's Liga ACB and the EuroLeague, in a move that reflects a broader shift in how European prospects are navigating the college basketball landscape.

Mario Saint-Supery‘s college chapter was brief, but far from forgettable. The 6-foot-4 point guard spent one season at Gonzaga, where he averaged 8.6 points per game, shot 40% from 3-points range, and started the final eight games of the season. His standout moment came in the WCC tournament title game against Santa Clara, where he dropped 21 points. In two NCAA tournament games, he recorded 13 assists and just four turnovers — a remarkably clean performance for a freshman under pressure.

Now, that chapter is closed. Valencia Basket officially announced on Saturday that the EuroLeague club had signed Saint-Supery to a long-term deal. The club’s statement left little doubt about the excitement surrounding his return: « The Little Prince will make the Roig Arena his new palace. » On Instagram, Saint-Supery kept it simple and heartfelt: « Zag nation, thanks for everything. »

A Significant Blow to Gonzaga, a Major Win for Valencia

The timing makes this move particularly impactful. The transfer portal is closed, leaving Gonzaga with limited options to replace a talented point guard in July. The loss is especially sharp given that the Bulldogs are set to compete in the new Pac-12 for the first time since 1979 when the 2026-2027 season tips off — a high-profile moment that will now unfold without one of their most promising young players.

For Valencia Basket, the calculus is straightforward: they are reclaiming a player who had already established himself as a star in the Liga ACB before ever setting foot on a college campus. The nickname « El Principito » — The Little Prince — was earned in Spain, and now he returns to the league where his reputation was built, this time with a year of elite American college basketball added to his résumé.

A Rare Outlier in the College-to-Europe Pipeline

Saint-Supery’s decision stands out as a notable exception to the broader pattern of European talent flowing toward American college basketball. While the NCAA’s 5-for-5 rule has created constraints on international players’ timelines in college, and while one season at a program like Gonzaga can sharpen a player’s game, most young European prospects still view a year in the college system as a valuable stepping stone before turning professional.

What makes Saint-Supery’s case unique is his pre-existing status in Spain’s Liga ACB. Few international freshmen arrive at American colleges with an established professional reputation and a nickname already earned in a top European league. For most young prospects, one year at Gonzaga or a similar program remains the preferred path to development. But for a player who already has standing in the EuroLeague and a club willing to offer a long-term contract, the calculus shifts dramatically.

Saint-Supery’s return to Valencia is less a sign of a broader exodus and more a reminder that elite European talent will always have options — and sometimes, home proves to be the better one.
