Smith pulled Detroit to 69-63 on a 3-pointer with 7:27 left in the period, the Green made back-to-back 3s followed by another from Bayless to stretch Boston's lead to 78-63. The Celtics finished the period with eight 3s and led 95-84 entering the fourth.
Monroe's three-point play with 9:28 remaining cut Boston's lead to 97-89, then Bynum pulled up for a jumper on a fast break to get the Pistons within six.
Detroit stayed within reach and pulled to 113-109 on two free throws by Bynum, but the Pistons had to foul and Humphries sealed it by making two from the line.
The Celtics shot 50 percent in the second quarter and led by 13, but Detroit closed the half on a 9-2 run to pull within 57-49 at the break.
