SAN ANTONIO — Russell Westbrook scored 31 points to lead the Oklahoma City Thunder in a victory over the San Antonio Spurs 113-100 in a Saturday showdown of NBA division leaders. Westbrook, who hit 13-of-22 from the floor and added eight assists for the Thunder, netted 11 points in the third quarter as Oklahoma City improved the NBA's best record to 22-4, while the Spurs fell to 21-6.
