MEMPHIS, Tenn. (AP) Erik Spoelstra took the first matchup with his former assistant.

Tyler Johnson matched his season high with 22 points, Dion Waiters added 15 and the Miami Heat snapped their two-game losing streak with a 90-81 victory over the Memphis Grizzlies on Friday night.

The game was the first that matched Spoelstra against first-year Memphis coach David Fizdale.

With a number of Heat players on the injury list, Johnson provided a boost for Miami, particularly in the first half.

''He's being aggressive where we need him to be aggressive,'' Spoelstra said. ''He's an example of the ball finding energy, but the ball has to move to find that energy.''

James Johnson added 13 points and Josh Richardson finished with 12 for Miami.

Mike Conley, who came off the bench, led Memphis with 16 points but shot only 5 of 15 from the field. JaMychal Green finished with 14 points for Memphis, which played without reserve Zach Randolph following his mother's death and had its six-game winning streak snapped.

The Heat played without a number of players due to injuries. The latest was point guard Goran Dragic, who missed the game because of a sore left elbow. He joined Wayne Ellington, Willie Reed and Justise Winslow on the Miami injured list.

Miami made up for the personnel shortage by hitting 12 of 31 outside the arc and forcing 18 turnovers, leading to 23 points. The Heat jumped to an early lead, built it to as many as 17 and led from start to finish.

''We were a little behind the eight-ball with Goran being out,'' Tyler Johnson said. ''Everybody did what they were supposed to do in order for us to get out of here with a win.''

Miami used 3-point shooting in the third quarter, hitting six of its first nine long-distance shots. That helped the Heat build their biggest lead to 17 before a 71-57 lead into the fourth.

Meanwhile, the Memphis offense, which seemed out of sync most of the night, continued to sputter. Memphis never got closer than eight points in the final quarter.

''Their speed really impacted us,'' Fizdale said. ''We never got organized. We never had a toughness about us. We didn't play with the attitude that we've had over the last six games, especially defensively.''

TIP-INS

Heat: In announcing Dragic would not play, Spoelstra said the guard's elbow ''is just not getting better.'' ...

PLAYING THROUGH PAIN

Waiters was questionable with a lingering right groin injury, but started. ''To be honest, I'm about 60 percent out there. I feel like my team needs me,'' he said.

''If the injury's not killing me . I'm going to battle through it. I'm going to fight. That's who I am.''

NO Z-BO

The team granted Randolph an indefinite leave of absence after the death of his mother, Mae Randolph, on Thanksgiving Day. ''Zach and his mother had an inseparable bond,'' Grizzlies General Manager Chris Wallace said in a statement released by the team. ''Mae was so fiercely proud of her son, his accomplishments and his truly special place in the hearts of Memphians and the Grizzlies family.'' Conley said: ''I called (Randolph), and we cried on the phone together. It was emotional, and that doesn't leave you in 24 hours.''
