The Oklahoma City Thunder and Cason Wallace agree on a 5-year extension.

Oklahoma City Thunder guard Cason Wallace has agreed to a 5-year, $139 million rookie-scale extension, ESPN’s Shams Charania reported on Sunday.

Wallace, a third-year guard drafted No. 10 overall in 2023, had an impressive campaign that saw him make the All-Defensive Second Team in 2026. He was also named All-Rookie Second Team in 2024.

With the departure of Lu Dort via trade in free agency, Wallace slides in as the starting guard next to Shai Gilgeous-Alexander in the backcourt. In 77 games, Wallace averaged 8.6 ppg and shot 35.6% from the 3-point range. Wallace led the NBA in total steals and deflections last season.
