Klay Thompson scored 21 of his 23 points in the first quarter, matching a Dallas record by hitting seven 3-pointers in the period, and the Mavericks breezed past the NBA-worst Washington Wizards 130-108 on Monday night. Thompson equaled the Mavericks record for 3s in any quarter, set in February 2022 by Luka Doncic, who has been sidelined since straining his left calf on Christmas Day. Thompson owns the NBA record for 3s in a quarter with nine, set in January 2015 during his 11-year run with the Golden State Warriors.
