Augustas Marčiulionis Bio
Augustas Marčiulionis (born 21 March 2002) is a Lithuanian basketball player who most recently played for the South Bay Lakers of the NBA G League. He stands 1.93 metres (6 ft 4 in) tall, weighs 91 kilograms (200 lb), and plays the point guard position. After spending the 2025-26 G League season with South Bay, he signed a contract with Rytas Vilnius of the Lithuanian Basketball League (LKL) in February 2026.
A graduate of Saint Mary’s College of California, Marčiulionis developed into one of the top guards in the West Coast Conference (WCC) during a four-year college career. He is the son of Hall of Fame player Šarūnas Marčiulionis, continuing a prominent Lithuanian basketball lineage. Across professional, collegiate, and national team levels, he has built a résumé that includes conference player-of-the-year honours and a Basketball Champions League title.
Early Life and Background
Augustas Marčiulionis was born on 21 March 2002 in Vilnius, Lithuania. Growing up in the Lithuanian capital placed him in one of Europe’s strongest basketball environments, where the sport is woven into daily life and community identity. From an early age, he was surrounded by the game through his family’s deep ties to Lithuanian basketball.
His father, Šarūnas Marčiulionis, is a Basketball Hall of Fame inductee known internationally as one of the pioneering Soviet and Lithuanian players to succeed in the NBA. That connection gave Augustas direct exposure to elite-level training habits and professional expectations. He also represented Lithuania at youth levels, including the U16 and U18 national teams, gaining international experience before finishing secondary school.
Before enrolling at Saint Mary’s, Marčiulionis joined the junior professional ranks in his home country. He debuted with BC Perlas during the 2018-19 season while also aligned with Rytas Vilnius. Those early years in the Lithuanian system helped him develop the fundamentals and composure that would later translate to the American college game.
Path to Basketball
Marčiulionis entered the professional pathway through Vilnius, splitting time between BC Perlas and Rytas Vilnius from 2018 to 2021. He played under amateur contracts during that stretch to keep his NCAA eligibility intact, a deliberate plan that delayed any full professional salary but preserved the option of a major U.S. college career. On 19 September 2020, he debuted in the Lithuanian Basketball League, contributing to a 106-77 opening-night win over Juventus Utena.
Alongside his club schedule, Marčiulionis continued to progress in Lithuanian national team programs. In 2020, he was invited to train with the senior Lithuania men’s national basketball team ahead of the EuroBasket 2022 qualification window. He also represented Lithuania at the 2021 FIBA U19 World Cup, adding high-level international competition to his development.
On 16 June 2021, Marčiulionis signed a letter of intent to play at Saint Mary’s College of California, formally beginning his next chapter. The move was aimed at testing himself in the West Coast Conference, one of the most guard-friendly leagues in U.S. college basketball, and at raising his profile ahead of a professional future.
Augustas Marčiulionis Career
Early Career (2018-2021)
Marčiulionis began his senior career with BC Perlas in the 2018-19 season, working his way into the rotation as a teenager. He spent the next two seasons developing within the Vilnius basketball ecosystem, bouncing between Perlas and Rytas Vilnius on amateur deals. The dual registration kept him close to top-level Lithuanian coaching while shielding his NCAA status.
By the 2020-21 campaign, he was contributing to Rytas Vilnius in the LKL and gaining valuable minutes in domestic competition. Those seasons laid the foundation for the confidence and ball-handling skills he would later showcase in the United States. He finished his pre-college stretch with a senior national team invitation already secured.
Saint Mary’s Breakthrough (2021-2025)
Marčiulionis played four seasons for the Saint Mary’s Gaels, growing from a reserve guard into the team’s offensive engine. In his freshman 2021-22 season, he appeared in all 34 games, starting 13, and averaged 3.1 points, 1.8 assists, and 0.9 steals per game. His role expanded steadily, and his 11-point high showed flashes of scoring upside.
As a sophomore in 2022-23, Marčiulionis played all 35 games and lifted his scoring to 5.9 points per game, although his three-point shooting sat at 25 percent. He opened the year as a starter before settling into a bench role, learning to produce in shorter stints. His season high of 14 points hinted at the larger offensive load he would soon carry.
The junior 2023-24 season marked his true breakthrough. Marčiulionis started all 34 games, averaged 12.4 points, 3.4 assists, and one steal per game, and raised his three-point percentage to 34 percent. He delivered three double-doubles, posted a high of 28 points, and led Saint Mary’s to the 2024 West Coast Conference tournament title, the program’s first since 2019. He was named WCC Player of the Year and WCC Tournament Most Outstanding Player, becoming only the second Gael to sweep both awards after Matthew Dellavedova in 2012.
His senior 2024-25 campaign cemented his place in school history. Starting all 35 games, he led Saint Mary’s with 14.2 points and 5.9 assists per game, scored in double figures 27 times, and reached 20 points seven times, including a 27-point high. He again shot 34 percent from beyond the arc, dished out five or more assists in 24 games, and earned a second consecutive WCC Player of the Year honour, the first Gael to repeat since Steve Gray in 1962-63. He also joined Matthew Dellavedova and Emmett Naar as the only Gaels to record at least 1,000 points, 500 assists, and 100 steals in an NCAA career, and received the Lou Henson Award.
South Bay Lakers Era (2025-2026)
Following the 2025 NBA draft, in which Marčiulionis went undrafted, he signed an Exhibit 10 contract with the Los Angeles Lakers on 27 July 2025. He was waived on 18 October before the regular season, then joined the South Bay Lakers training camp roster on 29 October. He debuted on 8 November 2025 against the Valley Suns, finishing with 4 points, 2 assists, and 2 rebounds.
Playing time was limited through November as he worked back from a prior injury. Across nine appearances in the 2025-26 NBA G League season, Marčiulionis averaged 5.4 points, 1.9 rebounds, 3.4 assists, and 0.7 steals in 16.1 minutes per game. The stint gave him his first sustained exposure to the professional American game.
On 26 February 2026, Marčiulionis signed a contract to return to Rytas Vilnius, rejoining the Lithuanian Basketball League and the Basketball Champions League (BCL). Rytas went on to win the 2026 FIBA Champions League title, adding a major European club trophy to his résumé.
Driving Style and Strengths
Marčiulionis is a classic pass-first point guard with poise well beyond his years. His strengths include a high basketball IQ, a steady perimeter jumper that has settled at around 34 percent from three in college, and the ability to orchestrate an offence. He excels as a pick-and-roll playmaker and brings defensive activity at the point of attack, using quick hands to generate steals.
Notable Events and Milestones
Signature milestones include back-to-back WCC Player of the Year awards in 2024 and 2025, the 2024 WCC tournament title, and his selection to the WCC All-Tournament team in consecutive seasons. He also reached the rare 1,000-point, 500-assist, 100-steal club at Saint Mary’s and won the 2026 FIBA Champions League with Rytas Vilnius.

2025 Season Performance
The 2025 calendar year spanned the end of Marčiulionis’s senior season at Saint Mary’s and his transition to professional basketball. He completed his college career as a second consecutive WCC Player of the Year, leading the Gaels in scoring and assists before declaring for the NBA draft. His performance kept him on NBA radars even as he went undrafted.
After going unselected in the 2025 draft, he signed an Exhibit 10 deal with the Los Angeles Lakers and joined the South Bay Lakers. Limited minutes and an early-season injury slowed his rhythm, but his playmaking traits remained visible in nine G League appearances. The season ended with his February 2026 return to Rytas Vilnius.
Looking ahead, the 2026 portion of his career is centred on Rytas Vilnius, where he is competing in both the LKL and the Basketball Champions League. With the BCL title already secured and another WCC Player of the Year on his shelf, Marčiulionis enters his next professional chapter with growing momentum and a clear path back to European stardom.
