Game 4 is Saturday in Atlanta.
The Hawks were up 84-78 with the shot clock running down when Teague launched a running shot from the wing after his foot seemed to clip the line. It counted, even after a video review.
Korver clinched it with the last of his four treys, putting Atlanta up 92-80 with 1:41 remaining.
Teague scored 22 points and Korver added 20 to lead the Hawks, who are playing with confidence and swagger against an Indiana team that struggled down the stretch and is still scrambling to regain the form it showed much of the season.
Lance Stephenson led the Pacers with 21 points, and Luis Scola added 17 in another stellar performance off the bench that at least gave Indiana hope. But Paul George was held to 12 points on 3-of-11 shooting, George Hill made only 1-of-11 from the field, and Roy Hibbert continually missed shots close to the hoop.
GRIZZLIES 98, THUNDER 95, OT
MEMPHIS, Tenn. • Mike Conley scored five of his 20 points in overtime, and Memphis went up 2-1 in the series.
The Grizzlies won their second straight overtime game after blowing a fourth-quarter lead. This time, they led by 17 before going cold for most of the final 7:43 of regulation. Courtney Lee clinched the win, hitting three of four free throws in the final 10.9 seconds of OT.
Game 4 is Saturday night in Memphis.
NBA scoring champ Kevin Durant and Russell Westbrook each scored 30 for the Thunder who even got another four-point play in the final minute to force overtime. This time, it was Westbrook's turn with 26.6 seconds left.
But Durant missed all eight 3-point attempts and was 10 of 27. Westbrook was 9 of 26. The Thunder hit only 3 of 12 overall in overtime.
Zach Randolph scored 16 points and had 10 rebounds for Memphis, which now has won 15 straight at home.
CLIPPERS 98, WARRIORS 96
OAKLAND, Calif. • Blake Griffin scored 32 points and grabbed eight rebounds, DeAndre Jordan had 14 points and 22 rebounds and Los Angeles outlasted Golden State to take a 2-1 lead in the series.
The frontcourt tandem bullied and bruised the Warriors inside to power the Clippers ahead by 18 points in the third quarter. And they did just enough late to silence a rocking, gold-shirt wearing sellout crowd of 19,596 to regain home-court advantage.
Klay Thompson scored 26 points, and Stephen Curry had 16 points and 15 assists to rally the Warriors back. But Curry forced a contested, step-back 3-pointer over Chris Paul in the final seconds to seal the Clippers' victory.
Game 4 of the best-of-seven series is Sunday in Oakland.
