The Dallas Mavericks have locked up first-round pick Sergio de Larrea, signing the Spanish guard to a four-year, $16.3 million rookie contract. NBA insider Marc Stein reported Friday that the deal is worth the full 120% of the rookie scale, completing the signing of the No. 25 overall selection acquired from the Los Angeles Lakers on draft night.
The contract comes as Dallas prepares to integrate De Larrea into its rebuilding core following a disappointing 26-56 campaign in 2025-26. The Mavericks finished 12th in the Western Conference and missed the playoffs for a second consecutive season, prompting an offseason focused on developing young talent alongside reigning Rookie of the Year Cooper Flagg.
De Larrea is expected to make his first appearance in a Mavericks uniform during NBA Summer League next week. The event will provide Dallas with an early opportunity to evaluate his ability to run an offense, create scoring opportunities, defend NBA guards, and translate his perimeter shooting against higher-level competition.
The 19-year-old arrives after four professional seasons with Valencia, one of Spain’s premier clubs. His most productive campaign came in Liga Endesa during the 2025-26 season, where he averaged 9.7 points, 3.7 assists, and 3.0 rebounds in 18.3 minutes over 28 games. He shot 44.3% from the field and an impressive 40.7% from three-point range while converting 83.3% of his free throws.
Those numbers represented significant growth in offensive responsibility. De Larrea’s increased role in Spain’s domestic league contrasted with his more limited minutes in the EuroLeague, where he averaged 3.6 points and 2.2 assists in 10.7 minutes across 26 appearances while shooting 40.3% from the field and 34.3% from beyond the arc. The difference reflected Valencia’s deeper veteran rotation in European competition rather than a decline in his overall development.
Across 95 professional appearances with Valencia, De Larrea averaged 6.0 points, 2.7 assists, and 2.1 rebounds while shooting 44.9% overall and 41.0% from three-point range. His outside shooting has consistently been one of his strongest attributes, although improving his playmaking efficiency—he averaged 2.7 assists against 1.5 turnovers—will be an important part of his transition to the NBA.
Dallas has already added another lottery talent this offseason after selecting Morez Johnson Jr. with the ninth overall pick before trading for De Larrea later in the first round. The Mavericks also drafted Tobi Lawal and Vsevolod Ishchenko in the second round, giving the franchise multiple developmental prospects as it reshapes its roster.
The Mavericks’ long-term foundation already features Flagg, who averaged 21.0 points, 6.7 rebounds, and 4.5 assists. Max Christie emerged as another key contributor by averaging 12.3 points while shooting 40.4% from three, and Daniel Gafford anchored the interior with 9.5 points, 6.9 rebounds, and 65.5% shooting from the field.
