His layup — his third shot of the possession — came up short, a microcosm of Miami's night.
"I just absolutely missed it," James said. "It was a (tale) of what type of game we were playing."
Arenas' fourth 3-pointer of the night came with 9:40 left, giving the Grizzlies an 81-64 lead. Mayo stretched the lead to 86-66 with another 3-pointer midway through the fourth, and the Grizzlies soon finished it off.
"We knew they were going to make a run but we withstood it," Randolph said. "We kept playing and got stops."
NOTES: Memphis' 13-point edge was the biggest lead by a visitor in Miami after the first quarter since San Antonio led 29-14 after the opening 12 minutes at the Heat on March 16, 2010. ... Memphis guard Tony Allen was not with the Grizzlies, out because of a facial laceration suffered in Dallas on Wednesday night. ... Harris, who has impressed the Heat of late, got first-quarter minutes for just the third time this season.
