AUBURN HILLS, Mich. -- LaMarcus Aldridge scored 27 points and Greg Oden had a career-high 13 rebounds to help the Portland Trail Blazers beat the Detroit Pistons 96-85 Sunday.

Brandon Roy scored 19 points and Oden finished with 10 for Portland, which has won four straight. The Pistons fell to just 6-6 since Allen Iverson joined the team.

Richard Hamilton had 18 for Detroit, which is 0-4 on Sundays and 10-2 during the rest of the week.

As they have done all season on Sundays, the Pistons got off to a terrible start. Detroit's starters were a combined 1-for-9 in the first quarter, and fell behind by 14 at one point.

Later, Detroit's reserves went on a 10-0 run that helped the Pistons get to 45-42 before Portland scored the final five points of the half. Aldridge had 17 points in the half, 11 more than any Piston.

Portland threatened to pull away throughout the third, but Detroit was able to keep itself in the game. Hamilton's jumper at the quarter buzzer cut the lead to 70-64.

Amir Johnson's put-back tied the game with 9:04 left, and Arron Afflalo put them ahead with two free throws on Detroit's next possession.

Steve Blake, though, answered with a 3-pointer, and Roy's three-point play moved Portland up 85-80 with 5:31 left.

Roy and Nicolas Batum hit jumpers on the next two possessions, giving Portland a nine-point edge, and the Pistons never seriously threatened again.
