The Spurs, who entered the game tied with Houston for the worst record in the Western Conference, won their second straight game. The Spurs had lost 11 straight games before this mini streak.

San Antonio got 21 points from Keldon Johnson, 19 points from Romeo Langford and 18 from Vassell, who had missed San Antonio's previous contest due to a knee injury.
