Gui Santos Bio
Guilherme Carvalho dos Santos, known professionally as Gui Santos, is a Brazilian professional basketball player for the Golden State Warriors of the National Basketball Association (NBA). Born on 22 June 2002 in Brasília, Brazil, Santos plays as a forward and stands 201 cm tall, providing length and versatility on both ends of the floor. He began his professional career in 2018 with Minas in the Novo Basquete Brasil (NBB) and has since developed into a contributor for one of the NBA’s most established franchises after being selected in the 2022 NBA Draft. His accolades include being named the NBB Sixth Man of the Year in 2022.
Early Life and Background
Gui Santos was born in Brasília, the federal capital of Brazil, on 22 June 2002. He grew up in a basketball family, with both parents having played the sport at a competitive level. His father, Deivisson, is a former professional basketball player who spent five seasons in the NBB, while his mother, Lucineide, also played the game. The household environment gave Gui early and consistent exposure to the rhythms, terminology, and discipline of competitive basketball, and his development was shaped by a clear understanding of what a professional career demands.
As a teenager, Santos came to wider attention when he was selected as one of the Brazilian representatives at Basketball Without Borders, a development camp organized by FIBA and the NBA that brought together 64 prospects from Latin America for training sessions in Medellín, Colombia. He also attended the FIBA Americas Youth Elite Camp in Campinas, Brazil, at the end of 2018. Those experiences placed him alongside top age-group talent from across the region and helped him benchmark his skills against elite international competition. By that point, his trajectory toward a professional career in the sport was already firmly established.
Path to Basketball
Santos entered the professional ranks with Minas during the 2018–19 NBB season at only 16 years of age, making his debut for one of Brazil’s most respected clubs. Because he was still in school, he was not always able to follow the senior team’s full routine, but he gained valuable experience in three NBB appearances against Joinville, Vasco, and Sesi Franca. In the 2019 Basketball Development League (LDB), the Brazilian U-20 championship, he led Minas with averages of 14.5 points, 6.4 rebounds, and 2.6 assists, signaling his readiness for a larger role.
During the 2019–20 NBB season, Minas head coach Léo Costa expanded Gui’s minutes and responsibilities, helping him transition from a developmental prospect into a regular contributor. In April 2021, Santos was named to the World Team for the Nike Hoop Summit, one of the most prestigious showcases for top international prospects, and shortly afterward declared for the 2021 NBA Draft. After another strong NBB season in which he was named Sixth Man of the Year, he re-entered the draft process and was selected by the Golden State Warriors with the 55th overall pick in 2022.
Gui Santos Career
Early Career at Minas (2018–2022)
Santos spent the first four seasons of his professional career with Minas, where he grew from a teenage debutant into a recognized NBB talent. In his first NBB season, he averaged 6.7 points, 5.7 rebounds, 2.5 assists, and 10.5 efficiency in 23.0 minutes per game, a strong baseline for a 16-year-old. He credited Minas teammates Alex Garcia and Leandro Barbosa, both veteran Brazilian guards with extensive NBA experience, for helping him shape his game and adjust to the demands of senior basketball.
His development accelerated each year. In 2019, he led Minas in the LDB, and by 2020, he was a regular member of the senior squad. On 3 September 2021, he scored a career-high 34 points for the Minas U-20 team in a 72–77 away win over Flamengo U-20. The following season, he was named the NBB Sixth Man of the Year after averaging 10.1 points and 5.1 rebounds, cementing his status as one of the most promising Brazilian forwards of his generation.
Golden State and Santa Cruz Warriors Era (2022–Present)
After being selected 55th overall in the 2022 NBA Draft, Santos joined the Golden State Warriors for the 2022 NBA Summer League. He was then assigned to the Warriors’ NBA G League affiliate, the Santa Cruz Warriors, where he was named to the G League’s inaugural Next Up Game for the 2022–23 season, a recognition reserved for top young prospects in the league.
On 7 November 2023, Santos was signed by the Golden State Warriors to a three-year contract, which runs through 2026. Throughout the following seasons, he was assigned several times to Santa Cruz to continue his development. On 15 January 2025, he made his first career NBA start, recording 5 points, 3 assists, and 7 rebounds in a narrow 116–115 victory over the Minnesota Timberwolves. On 29 June 2025, the Warriors exercised the team option on his contract, confirming his place in the franchise’s plans.
National Team Career
Gui Santos has represented Brazil at multiple age levels. In 2019, he helped Brazil win a gold medal at the FIBA South America Under-17 Championship in Chile, scoring 27 points against Argentina in the final. In February 2020, he was called up by head coach Aleksandar Petrović to the Brazilian senior national team, and he scored 11 points across two games against Uruguay in the 2021 Copa América qualifiers. He later made his senior national team debut during the 2022 FIBA AmeriCup qualification.
Playing Style and Strengths
Santos is a long, versatile forward whose 201 cm frame allows him to defend multiple positions and finish comfortably around the rim. He reads the game with poise beyond his years, a trait shaped by mentors such as Alex Garcia and Leandro Barbosa during his Minas years. His shooting touch, rebounding instincts, and willingness to facilitate have made him a useful connective piece within Golden State’s motion-based system.
Notable Events and Milestones
Among Santos’s most significant career moments are his gold medal performance at the 2019 FIBA South America Under-17 Championship, his NBB Sixth Man of the Year award in 2022, and his first NBA start against Minnesota in January 2025. The Warriors’ decision in June 2025 to pick up his team option underscored his growing value within the organization.
Gui Santos Family
Family Background and Basketball Lineage
Basketball runs through Gui Santos’s family. His father, Deivisson, was a professional player who spent five seasons in the NBB, and his mother, Lucineide, also played the sport. That pedigree provided Gui with an early understanding of the game’s demands and helped shape his path toward a professional career in Brazil’s top league and, eventually, the NBA.
Personal Life
Gui Santos maintains a close connection to his family roots in Brasília and has spoken publicly about the influence of his parents on his career. The Brazilian outlet O TEMPO has described him as a fan favorite, a reflection of the rapport he has built with supporters since his teenage years at Minas.
2025 Season Performance
The 2025 season marks Gui Santos’s most significant step yet within the Golden State Warriors’ rotation. After being signed to a three-year deal in November 2023 and shuttling between the Warriors and their G League affiliate in Santa Cruz, he has earned a more consistent presence at the NBA level. His first career start on 15 January 2025, a 116–115 win over the Minnesota Timberwolves in which he posted 5 points, 3 assists, and 7 rebounds, signaled the franchise’s growing trust in his ability to contribute in meaningful moments.
The Warriors’ decision on 29 June 2025 to exercise his team option confirmed his status as part of Golden State’s long-term plans. With his contract running through 2026, Santos has an opportunity to consolidate his role, refine his shooting, and continue providing defensive versatility and playmaking from the forward position. Continued assignments to Santa Cruz have allowed him to accumulate on-court reps, an arrangement that has clearly accelerated his development.
Looking ahead, the outlook for Gui Santos in the 2025 season is one of steady growth. Surrounded by championship-caliber veterans and supported by a developmental pipeline through Santa Cruz, he is positioned to expand his minutes and responsibilities. If his early-season trajectory continues, he could emerge as a reliable rotation piece for the Warriors while further establishing himself among the most promising Brazilian players in the NBA.
