"The game got away from us," Carlisle said. "A lot of guys got hot. Collectively, I think their collective will was stronger than ours. After a really encouraging first half and a couple minutes in the third quarter, it just went the other way."
Lance Stephenson's layup early in the second half tied the game at 51, and Hibbert's free throw put the Pacers ahead. Indiana expanded the lead to 59-54 on a 3-pointer by Stephenson.
A 3-pointer by Young pushed the Pacers ahead 70-59 with 4:02 left in the third quarter. Stephenson hit another 3 to make it 75-61 with 2:39 left in the third quarter. Indiana led 76-67 at the end of the period.
Stephenson scored 10 points in the third quarter as the Pacers held the Mavericks to 28 percent shooting in the period.
A three-point play by Gerald Green gave the Pacers an 83-69 lead and a 3-pointer by Young pushed Indiana's lead out to 18 points.
"We put ourselves in good position to win the game in the first half, then we come out and we couldn't stop anything in the second half," Mavericks forward Shawn Marion said. "I don't know why we are doing these things. We can't seem to sustain anything. We are continuing to have lapses, mental lapses."
Pacers forward Paul George said he hopes the strong performance is the start of a trend. Indiana entered the season as one of the favorites in the Eastern Conference, but the Pacers have struggled to score without Danny Granger, a former All-Star who is out with an injured left knee.
"We don't want to look too far ahead," George said. "We still have a lot of work to do. It's a good start. It looks like we're starting to get things together. We haven't lost hope. We're fine."
