The Pacers won the NBA season-opener for both teams by outscoring Washington 16-7 in the overtime.
They held a slim 48-45 lead at the half, but Washington took a 58-48 advantage at the 9:17 mark of the third. Indiana then slowly closed the gap in the fourth.
Indiana's Mike Dunleavy had 25 points and 12 rebounds. Ike Diogu and David Harrison scored 13 points apiece for the injury-depleted Pacers, who played without star forward Jermaine O'Neal (knee) and center Troy Murphy (achilles).
Washington got a game-high 34 points from Gilbert Arenas.
They also had won three straight at Indianapolis.
