It was the Pacers' fourth consecutive loss.

In Memphis, Tennessee, Shaquille O'Neal moved into eighth place on the NBA career scoring list as Phoenix beat Memphis 101-89.

O'Neal had 24 points, 13 rebounds and three blocks and his fourth-quarter dunk moved him past Oscar Robertson on the career scoring list with 26,711 points.
