INDIANAPOLIS – Ja Morant had 23 points, 10 assists and another ferocious dunk, and the Memphis Grizzlies beat the Indiana Pacers 130-112 to extend the NBA’s longest current winning streak to nine games. Desmond Bane scored 25 points to lead the Grizzlies, who tied Denver for the Western Conference’s best record at 29-13. Neither Bane nor Morant was needed in the fourth quarter. Morant’s soaring slam over Jalen Smith made it a 20-point game with 4:20 left in the third, and Memphis led by as much as 34 in the fourth.
