San Antonio answered with back-to-back 3-pointers from Zach Collins and Walker, and after a free throw by Pokusevski, another trey from Walker gave the Spurs an eight-point lead. The hosts led 68-56 at the break.

Murray had 14 points, six assists and six rebounds before halftime. Johnson tallied 12 for San Antonio.
