LaMarcus Aldridge scored 23 points, Kawhi Leonard added 19 and the San Antonio Spurs beat the Memphis Grizzlies 97-90 on Thursday night in a possible first-round playoff preview. San Antonio opened a four-game homestand by moving two games behind idle Golden State for the league's best record. Memphis (40-32) is seventh in the Western Conference, which would result in a first-round matchup with San Antonio if the standings remain.
