TORONTO (AP) -- DeMar DeRozan had 15 points and a career-high 11 rebounds, Kyle Lowry added 11 points and 10 assists, and the Toronto Raptors opened their defense of the Atlantic Division title with an 109-102 victory over the Atlanta Hawks on Wednesday.
Amir Johnson had 16 points and 10 rebounds, Jonas Valanciunas scored 17 points, and Terrence Ross had 13 for the Raptors, who were an NBA-best 7-1 in the preseason.
Kyle Korver, Jeff Teague and Mike Scott each scored 20 points for the Hawks, and Paul Millsap had 13 points and 10 rebounds.
Atlanta's Al Horford, limited to 29 games last season by a torn right pectoral muscle, had 12 points and 13 rebounds. Horford connected on six of his 15 attempts, and his baseline jumper at 10:06 of the fourth was the 2,500th field goal of his career.
Back-to-back 3-pointers by Scott and DeMarre Carroll capped a 10-1 run to bring Atlanta within eight, 102-94, with 2:30 left in the fourth, and another 3 by Scott at 1:26 made it 103-99.
Lowry made a pair of free throws, but Patrick Patterson was called for goaltending on Carroll's shot, keeping the margin at four points.
DeRozan was fouled and missed both shots, but was fouled again as he grabbed his own rebound on the second. Given another chance, DeRozan made both to put Toronto up 107-101 with 32 seconds left. After Teague made one of two from the line, Patterson sealed Toronto's win with a fast break dunk.
