Mike Conley scored 26 points, Zach Randolph added 25 and the Memphis Grizzlies topped the Miami Heat, 107-102, at FedEx Forum Wednesday night, earning their 12th straight home win and keeping pace in the Western Conference playoff picture.
The Grizzlies remain one game back of the Phoenix Suns, who beat the New Orleans Pelicans, for the No. 8 seed.
The Heat fell back to the Eastern Conference's No. 2 seed with the loss, as the Indiana Pacers secured a victory over the Milwaukee Bucks. However, Miami is tied with the Pacers in the loss column.
Dwyane Wade (hamstring) missed his eighth straight game, and Chris Andersen (knee) also sat. Tayshaun Prince (ankle) missed his second consecutive contest.
The Heat led by as much as 10 in the second quarter, but Memphis used a late surge to cut the lead to four by halftime.
Behind 37 points from James, Miami reasserted itself during the third period, going up by as much as nine, but another late run by the Grizzlies erased the deficit. Courtney Lee, who scored 18, hit a buzzer-beating three-pointer, tying the game at 80 heading into the fourth quarter.
Marc Gasol, who posted 20 points and 14 rebounds, made a go-ahead dunk to put Memphis up 82-80 to start the final period, and from that point on, the Heat never again led.
The Grizzlies went up by as much as 12 in the fourth, taking a 107-95 lead late.
Randolph grabbed 11 rebounds to go along with his point total, and he started 9-of-9 from the floor, scoring 17 points in the first quarter.
Miami hit on 15 of its 25 three-point tries, but Memphis pounded Erik Spoelstra's club in the paint, 60-30. The Grizzlies also outrebounded the Heat, 41-27.
