PORTLAND, Ore. — LaMarcus Aldridge had a career-high 40 points along with 11 rebounds and the Portland Trail Blazers defeated the NBA-leading San Antonio Spurs 99-86 on Tuesday night.

Wesley Matthews added 21 points for the Blazers, who snapped a two-game losing streak.

Manu Ginobili had 14 points for the Spurs, who have lost only eight games this season.

Gary Neal's 3-pointer for San Antonio tied it at 78, but Aldridge's layup and Wesley Matthew's scoop gave Portland its biggest lead of the game so far at 82-78 with 7:03 left.
