BOSTON (AP) _ Kyle Lowry scored 35 points and had a key steal in the closing minute to lead Toronto over Boston.
DeMar DeRozan had 23 points and Patrick Patterson added 14 for the Raptors.
Rajon Rondo led Boston with a triple-double of 13 points, 15 assists and 10 rebounds. Jeff Green had 20 points for the Celtics, who have lost three straight after a season-opening win over Brooklyn.
With the score tied at 105, Lowry stripped rookie Marcus Smart and fed DeRozan for a fast-break layup with 33 seconds left. He was fouled on the play and hit the free throw.
Rondo’s two free throws sliced it to one, but Lowry nailed a fadaway jumper from the left wing with 8 seconds to play. Green back-rimmed a long 3 and Boston’s Jared Sullinger grabbed the rebound, but time ran out.
