The San Antonio Spurs defeated the Dallas Mavericks, 76-69, in the NBA 2K26 Summer League at Thomas & Mack Center on Saturday.

Flagg scored 31 points and Harper poured in 16 as Harper's San Antonio Spurs claimed a 76-69 victory over Flagg's Dallas Mavericks in an NBA Summer League showdown in Las Vegas. Despite his team being on the losing end, Flagg put on a clinic.

Mavericks forward Cooper Flagg, the league’s top pick weeks ago, had already played in one Summer League contest. Spurs’ guard Dylan Harper, who trailed Flagg at No. 2, had yet to don a San Antonio jersey. Both players performed well, with Harper on a minutes restriction.
