The Indiana Pacers no longer are just a nuisance.

Instead, they're threatening to topple the balance of power in the Eastern Conference.

On a night LeBron James was merely good and Dwyane Wade anything but for the Heat, the Pacers moved to a 2-1 lead in this best-of-seven Eastern Conference semifinal series with a 94-75 victory Thursday night at Bankers Life Fieldhouse."

We definitely feel that we can win this series," Pacers coach Frank Vogel said.

With Wade scoreless in the first half of what turned into a five-point outing and James merely mortal in a 22-point performance, the Pacers made it consecutive victories over the Heat, with Game 4 Sunday on the Pacers' court.

"Sunday is a must win for us, obviously," James said.

For Indiana, contributions from a variety of players left the Heat searching for answers and ultimately capitulating, with George Hill scoring 20, Roy Hibbert 19, Danny Granger 27 and David West 14.Hibbert also had 18 rebounds and five blocked shots.

"One of the best games I've ever seen him play," Vogel said.

Hibbert said he was taking advantage of the absence of injured Heat power forward Chris Bosh.

"Until they get him back," Hibbert said. "I'm going to keep doing the same thing."

Wade missed his first six shots and closed 2 of 13 from the field.

"Obviously I'll go back to the film and look at it," Wade said. "I missed some shots early, then missed some shots later. I've got to be a little more aggressive. Give them some credit. They did a good job when I got to the basket."

Even with point guard Mario Chalmers scoring a career playoff-high 25 points, the Heat simply lacked enough to stay competitive, with Bosh missing a second consecutive game with a lower-abdominal strain that likely will sideline him at least for the balance of this series.

"We're not scoring the ball," James said. "This is the result of us not making as much shots as we're accustomed to make."

The Pacers seized control in the third quarter with a 17-3 run to push to a 64-50 lead.

With Wade off his game, the Heat unable to make a 3-point shot, and James reduced to trying to win it on his own, the Pacers went from a 47-47 tie early in the third to a 69-55 lead entering the fourth.

"We're not going to win a ballgame with Chris Bosh out and me scoring five points obviously," Wade said. "So I take a lot of onus on that. So there's frustration in that."

While West and Granger were called for technical fouls in the third period, that aggression only seemed to fuel Indiana, with the Heat reduced to a seemingly nasty sideline moment between coach Erik Spoelstra and Wade.

"That was during a very emotional part of the game, when we were getting our butt kicked," said Spoelstra, who declined to directly answer whether Wade was injured. "That type of fire, that's good. That's the least of our concerns."

Despite Wade's first scoreless first half in 95 playoff appearances, the Heat were able to go into the intermission tied 43-43. Wade missed all five of his first-half shots.
