Raptors 85, Bulls 79: Jonas Valanciunas led a balanced attack with 15 points and nine rebounds and visiting Toronto used a big fourth-quarter run to subdue Chicago.

Seven players finished with eight or more points as the Raptors ended 2013 with eight wins in 11 games. Kyle Lowry had 13 points, DeMar DeRozan added 11 and Patrick Patterson 10 for the Atlantic Division leaders.

Luol Deng's 16 points paced the Bulls, who have dropped 11 of their last 16. Jimmy Butler poured in 15 points while Joakim Noah contributed seven points, 16 rebounds and six assists in a losing cause.

DeRozan's seven points represented the lone bright spot in a rough first quarter that saw Toronto escape with a 21-16 advantage. Chicago rallied to take the lead on D.J. Augustin's driving layup early in the second - part of a 16-2 run spanning the opening six minutes of the quarter - and the Bulls rode that surge to a 42-36 halftime edge.

Toronto kept Chicago from distancing itself in the second half, riding six points from Lowry to a 62-57 deficit after three. The Raptors then blew the game wide open in the fourth, getting seven points from Greivis Vasquez and eight from Patterson to fuel a 21-4 run that put them ahead by double digits with 4:47 left.
