Indianapolis - Despite having the biggest half-time lead in playoff history, this put his team in a 3-1 lead in the Eastern League semifinals on the way to a 129-109 victory, and Indiana Pacers coach Rick Carlisle wasn't ready to pay attention to the achievement.

"We haven't done anything yet," Carlisle said Sunday night.

Carlisle went on to highlight how the Pacers’ losers in each game of the second round of the second-round series with the top-seeded Cleveland Cavaliers and hopes his team maintain that mentality despite the win in the second straight conference finals.

"We will continue to get closer to this, just like we have everything to prove," Carlisle said. "We know people don't believe us … about scores and all of this, it makes no sense. Now, this game is history. So we have to keep the same attitude at the moment now."

The Pacers never trailed Sunday’s game, gaining an 80-39 advantage in halftime. Indiana forced Cleveland to score a turnover (14) than allowed shots (8). According to ESPN Research, the 41-point lead is the biggest lead in NBA playoff history, matching the 2017 Cavaliers, who led the Boston Celtics with 41 strokes in the Eastern Conference Finals.

"They completely ruled them," said Cavaliers coach Kenny Atkinson. "That's the story. In every way."

Cleveland won the first victory of the series in Game 3 Friday and was helped by the return of Evan Mobley, Darius Garland and De Andre Hunter. The Cavaliers also put the Pacers in a 3-2 zone defense in the second quarter of this game, bringing their shooting percentage to 21 and 38% (38%) from 3 innings.

The Pacers had an answer Sunday, shooting 15 points (60%) against the area and hit three of six 3-pointers.

"Our movie sessions are always ugly after the loss," said Pacers Tyrese Haliburton. "I feel like the coach is a poor guy when it comes to adjusting and getting the best from men. And I think we can follow that lead, his intensity is the time of the playoffs. It's easy to follow."

Halliburton scored 11 points with five assists and five rebounds. The Pacers had seven players finishing in double figures, with three-pointers - Obi Toppee, Pascal Siakam and Miles Turner - with 20 points.

In the playoffs, Indiana's 129 points made its best efforts in one game.

“We’re just energetic,” Halliburton said. “I think they set the tone from a physical perspective in the last game. That’s the conversation point for all their series. Today, we came out and set the tone from the jump and really just riding the wave.”

After winning 64 games throughout the season and leading the Eastern Conference, the Cavaliers are now on the verge of elimination. Garland scored 21 points, but Mobley was limited to 10 points, while Jarrett Allen scored 2 points and 2 rebounds.

"They took the game to another level and we didn't match it," Atkinson said. "We talked about this. We knew it was coming. You were trying to prepare for these things.

Now, the Cavaliers have reached star Donovan Mitchell 3-1 in the series, uncertain. He plans to undergo an MRI on his left ankle injured on Monday.

Game 5 is Tuesday in Cleveland.

"There will be a big hay factory coming," Carlisle said. "We respect their fans and what they are going there. A lot of work is going to do."
