Jeff Teague scored a playoff career-high 28 points, Paul Millsap added 25 and the eighth-seeded Hawks won their first road playoff game in three years, shocking top-seeded Indiana 101-93 to take a 1-0 lead in the first-round series.
Atlanta won its first road playoff game since Game 1 of the 2011 Eastern Conference semifinals at Chicago, and they'll have a chance to do it all again Tuesday in Game 2 before the best-of-seven series moves to Atlanta, where the Pacers have won only two times since December 2006.
Indiana was just 5 of 19 from the field in the decisive third quarter and shot just 35.6 percent in the second half, a 24-minute span in which it spent most of the time trying to dig out of a double-digit hole.
Paul George had 24 points, 10 rebounds and five assists, while Lance Stephenson finished with 19 points and seven rebounds and George Hill added 12 points.
