INDIANAPOLIS -- After battling injuries and failing to qualify for the 2015 NBA playoffs, the Indiana Pacers had plenty of energy and motivation entering Sunday's potential playoff-clinching game against the Brooklyn Nets.

It showed from the very beginning as Indiana qualified for the playoffs for the fifth time in six seasons.

Indiana led 39-19 after one quarter and 69-41 at halftime on its way to a 129-105 victory against the Brooklyn Nets on Sunday in Bankers Life Fieldhouse, securing a spot in the Eastern Conference playoffs.

With two regular-season games to play, Indiana will face either Toronto or Cleveland in the opening round of the postseason.

The Pacers are the No. 7 seed in the East at the moment. Detroit and Indiana are both 43-37, but the Pistons currently are the East's No. 8 seed because Indiana owns the tiebreaker.

"We wanted to play well and continue to build our habits," Indiana coach Frank Vogel said. "We were motivated, and I could see that in how hard we practiced Saturday. Because our playoff seed still is to be determined, we are going to continue to play like it. I thought Myles Turner really produced for us tonight. He has a lot of talent."

Turner led Indiana with 28 points and 10 rebounds, and George Hill had 18 points, five rebounds and four assists. Ian Mahinmi finished with 16 points and six rebounds, Paul George had 15 points, five rebounds and six assists, Solomon Hill contributed 13 points and 12 rebounds, and CJ Miles had 11 points. Indiana shot 55.3 percent (48 of 86).

"It really feels good," George said of clinching a playoff slot. "A year ago, we weren't healthy and didn't make it. We know how to play and knew we could do this."

George Hill said the Pacers wanted to remove all doubt early.

"A big point of emphasis was how we came out to start the game," Hill said. "We hoped to be a part of the playoffs again, and now we will."

Brooklyn, which has lost eight in a row, got 26 points from Sean Kilpatrick, 19 from former Pacer Donald Sloan and 16 from Shane Larkin.

"They shot the ball extremely well, and they are going to the playoffs," Brooklyn interim coach Tony Brown said. "We're not going to the playoffs, so what we were doing tonight was trying to evaluate some of our young players. Credit (Indiana). Other than that, I don't know what to tell you."

Kilpatrick said the Nets weren't ready.

"We came out flat, and if you do that against a playoff team, they will make you pay," Kilpatrick said. "They have a lot of veteran guys, like Paul George, and if you play like that against them, it gives you no chance."

The Pacers, who missed the 2015 playoffs, scored a season-best 39 first-quarter points on Sunday, replacing the 36 they scored against Cleveland on April 6. Indiana made 13 of 17 first-quarter field-goal attempts (76.5 percent) and was 26 of 43 (60.5 percent) through 24 minutes.

At the half, the Pacers had 32 points in the paint, and Brooklyn had 10.

Mahinmi said Indiana was frustrated by the way it approached Friday's game at Toronto and wanted to make amends.

"I wanted us to come out and be aggressive at the start, and that is what we did," Mahinmi said. "In our loss at Toronto, we didn't do that at all."

Indiana opened the third quarter with a 14-2 burst, increasing its lead to 83-43 with 8:59 remaining in the period, prompting a Brooklyn timeout. The Pacers led 104-72 through three quarters.

Turner had 12 first-half points, George and Miles each had 11 and Mahinmi contributed 10. The Pacers outrebounded the Nets 27-16 during the opening half. Indiana's non-starters contributed 33 first-half points, three more than Brooklyn got from its bench.
