AUBURN HILLS, Mich. -- Point guard Damian Lillard's spinning shot in the lane in the final second of overtime gave the Portland Trail Blazers a 111-109 victory over the Detroit Pistons on Sunday night at The Palace.
Power forward LaMarcus Aldridge led the Trail Blazers with 27 points and 12 rebounds, and Lillard finished with 23 points and seven assists. Small forward Nicolas Batum had 18 points, five rebounds and five assists for the Western Conference-leading Trail Blazers (21-4).

Point guard Brandon Jennings racked up 15 points, eight rebounds and 10 assists while center Andre Drummond added 13 points and 14 rebounds.
Portland is 10-0 against the Eastern Conference.
Drummond's putback dunk in the final minute of overtime tied it at 107-107. Lillard gave Portland the lead with 24.4 seconds remaining on two free throws, but Stuckey's pullup jumper tied it again.
After a timeout, Lillard drove into the paint for the game-winner.
The Pistons led by 13 early in the fourth quarter, but Aldridge's free throws with 3:48 remaining made it a two-point Detroit lead, 94-92. Smith answered with a three-point play, and Detroit held a slim lead until Blazers guard Wesley Matthews made two free throws with 30.8 seconds left for a 99-99 tie.
Neither team could convert in the remaining seconds, sending the game to overtime.
Smith surpassed his season high by making four hook shots in the third quarter, as the Pistons stretched a one-point halftime advantage to 84-73. Jennings, who was held to two first-half points, contributed eight points and four assists during the quarter as the Pistons outscored Portland 33-23.
