Norris Cole scored 18, and the Heat pulled out a tight win after blasting the Bulls 115-78 on Wednesday.
The Bulls hung in right until the closing minutes, but the Heat simply had too much in the end.
James hit just 6-of-17 shots and even got blocked on a layup by Nate Robinson in the third quarter. But the four-time MVP came through down the stretch, scoring 12 in the fourth.
