The Oklahoma City Thunder and center Isaiah Hartenstein agreed to a three-year extension through the 2028-29 season, sources told ESPN’s Shams Charania.
Hartenstein’s new contract includes $75 million in new money, bringing his total guaranteed earnings with the franchise to $134 million over five years, according to Charania.
The deal replaces a $28.5-million team option in his previous contract and reportedly includes a unique mutual option that allows the two sides to rework the agreement in 2028.
