Joe Johnson's bank shot jumper with 13 seconds left sent the game into overtime, and the Nets capitalized on the extra time.
Brook Lopez had a game-high 25 points for the Nets (30-22) on 8-of-19 shooting from the field while adding eight rebounds and two blocks. Reggie Evans had a monstrous night on the glass, grabbing 22 rebounds in addition to eight points and two blocks of his own.
George Hill led the Pacers (31-21) with 22 points, six assists and four rebounds. Indiana struggled to find any rhythm on offense and shot just 34.4 percent from the field and a pedestrian 5-of-22 from the three-point line.
Both teams shot poorly in the second half, as Brooklyn was just 37.8 percent from the field and 28.6 percent from the three-point line. Indiana shot 38.5 percent and just 16.7 percent from deep. The Nets led by as many as nine in the latter half before heading into the extra period.
