MIAMI — Dillon Brooks and Desmond Bane scored 21 points each, and the surging Memphis Grizzlies beat the Miami Heat 105-90 Monday night.

The win was Memphis’ fifth straight without leading scorer Ja Morant, who hurt his left knee against Atlanta on Nov. 26. The Grizzlies have not trailed during their streak.

All five Grizzlies’ starters finished in double figures. Steven Adams had 17 points and 16 rebounds, while Tyus Jones and Jaren Jackson scored 14 points each.

The Grizzlies opened the game on a 20-6 run and built an 11-point halftime lead. Then they maintained the double-digit advantage throughout the second half.

Miami’s Jimmy Butler returned from a four-game absence because of a bruised tailbone and scored 10 points before leaving for the locker room midway through the third quarter. He didn’t return. Butler favored his back after a hard fall in a missed driving layup early in the first quarter.

Memphis scored 27 points off of 23 Miami turnovers.

Tyler Herro had 24 points and Kyle Lowry finished with 17 points for the Heat, who have lost four of five and three straight at home.
