What happened: Sergio De Larrea has signed a four-year contract worth $16.3 million with the Dallas Mavericks, according to league sources cited by The Stein Line and DLLS Sports. The deal is set at a full 120% of the rookie scale, the maximum allowed. De Larrea is a Spanish guard who came up through Valencia.

Why it matters: The full 120% figure signals Dallas is committing to De Larrea as more than a project, locking in a rookie-scale guard for four years. It also confirms an earlier report that De Larrea planned to come directly to the NBA next season rather than remain overseas. For a Mavericks team reshaping its backcourt, the signing adds a controllable young piece on a cost-certain contract.

What to watch: Watch for how De Larrea factors into Dallas' guard rotation entering the 2026-27 season and whether the club brings him along immediately or eases his transition from the Spanish league.
