DALLAS (AP) -- Kyle Lowry scored 27 points, and the Toronto Raptors spoiled the home opener in Dallas, beating the Mavericks 102-91 on Tuesday night for the first 4-0 start in franchise history.
The Raptors took the lead for good on a 12-0 run that started in the middle of the fourth quarter. Jonas Valanciunas had six of his 16 points during the decisive stretch.
The Mavericks went almost 4 minutes without a basket after Dirk Nowitzki hit a 3-pointer for an 86-82 lead. Nowitzki finished with 18 points.
DeMar DeRozan scored 20 points, and Luis Scola had 19 points and 12 rebounds for the Raptors, who opened with three straight wins two other times in their first 20 seasons.
Lowry had a game-high 10 assists, and Toronto held Dallas to 6-of-22 shooting in the fourth quarter and 38 percent for the game. It's the second time the Raptors have held their opponent under 40 percent.
Deron Williams, who starred at a Dallas-area high school, had 13 points in his home debut for the Mavericks.
Dallas forward Dwight Powell, a Toronto native, had his first career double-double with 10 points, all in the first half, and 10 rebounds.
Valanciunas started the decisive run with a layup on an assist from Lowry and finished it with a tip-in and a pair of free throws after he was fouled getting a defensive rebound.
Dallas forward Chandler Parsons played 14 minutes in the first half of his second game after offseason right knee surgery, but didn't play after halftime for precautionary reasons. He scored nine points after getting two in 12 minutes in his debut Sunday at the Los Angeles Lakers.
