Will Bynum finished with 21 points and six assists in a reserve role for the Pistons, who ended a five-game homestand with a 1-4 mark. Rodney Stuckey and Ben Gordon donated 19 and 15 points, respectively.
Trailing by one, 94-93, with under five minutes to play, Patterson scored the first seven points of a 9-0 run to put the Rockets in front. Aaron Brooks capped the surge with two free throws to make it a 102-94 game with two minutes left.
Detroit never got closer than six the rest of the way.
The Pistons raced out to a 15-5 margin and led 28-20 after 12 minutes of action.
Houston charged back in the second quarter to make it a 51-51 game at the break.
The Rockets carried that momentum over to the second half, starting the third period on a 14-3 run. Shane Battier and Kyle Lowry each made three-pointers during the burst, which Martin capped with a jumper to give Houston a 65-54 edge with seven minutes to go.
But the Pistons ripped off seven straight points late in the stanza to get within two, 75-73, on Bynum’s trey. Detroit trailed by three, 78-75, heading to the fourth.
The Pistons used a 7-0 flurry early in the fourth to take an 82-80 edge on Charlie Villanueva’s three-pointer with 9:12 to play.
Houston won both meetings with the Pistons this season…Detroit was without guard Richard Hamilton (groin)…Rockets guard Courtney Lee (pneumonia) missed the game…Houston went 26-of-28 from the foul line, while the Pistons went 14-of-15 from the charity stripe…Greg Monroe had 12 points and 12 rebounds in defeat.
