SALT LAKE CITY – Al Jefferson scored 24 points, Mo Williams hit six 3-pointers and the Utah Jazz beat the Portland Trail Blazers 112-102 Monday night to extend their winning streak to a season-best five games.

The win was Utah's second in four days over the Blazers (33-41), losers of five consecutive.

Wesley Matthews scored 23 for Portland, still without leading scorer LaMarcus Aldridge because of a sprained ankle.

Rookie standout Damian Lillard added 17 points, including three 3-pointers to break the NBA's single-season rookie record (166) for 3s.

Utah moved a half-game ahead of the idle Los Angeles Lakers for the eighth Western Conference playoff spot, and two games ahead of Dallas.
