Oklahoma City swept the regular-season series with the Pacers last season, and Durant opened the game with a point to prove in the matchup of NBA Finals' hopefuls.
The NBA's leading scorer at 28.5 points per game hit 6 of his first 7 shots in the first quarter, scoring 14 of the Thunder's first 18 points. Oklahoma City led by as many as 14 points in the first quarter, stretching that to 19 points in the second quarter after Jeremy Lamb's 3-pointer put the Thunder up 43-24.
Lamb's 3-pointer capped a 15-4 run for Oklahoma City, all coming from its reserves — led by Jackson's seven point.
The Thunder shot 54.8 percent (23 of 42) in the first half, while Indiana shot just 32.6 percent (15 of 46).
