DeMar DeRozan scored 34 points and the Raptors held on for a 102-99 victory over the Indiana Pacers and a 3-2 lead in their first-round series Tuesday night when Solomon Hill's 3-pointer was ruled after the buzzer.
The Raptors overcame 39 points from Paul George and a 13-point deficit in the fourth quarter, getting 14 points from Kyle Lowry.
Bismack Biyombo had 10 points and 16 rebounds for the second-seeded Raptors, who can clinch the first seven-game playoff series victory in franchise history by beating the Pacers in Indiana on Friday night.
Jonas Valanciunas scored 11 and rookie Norman Powell had 10 for Toronto.
The Pacers made 13 of 29 from 3-point range but struggled from all over the floor in the fourth, making four of 15 shots and scoring just nine points in the period.
Trailing 90-77 to begin the fourth, the Raptors tied the game with a 15-2 run. Powell stole the ball from Monta Ellis and made a fast-break dunk to knot it at 92-all with 6:31 remaining, sending the sellout crowd of 19,800 into a frenzy.
Solomon Hill's 3 with 15.9 seconds cut it to 100-99, but DeRozan answered with a pair of free throws.
Indiana had the ball under Toronto's basket with 2.7 seconds left. Ellis inbounded to George, who fed Solomon Hill, and Pacers players threw their arms up in celebration when his shot from the left side went through the net. But video replay confirmed that the shot came too late.
