Indianapolis ? The Indiana Pacers’ joyride is over.

The Pacers breezed through the regular season and the first six games of the playoffs. Then came their trip to Miami.

Behind rookie Dwyane Wade and Lamar Odom, the Heat won two in a row to even the second-round series. The victories extended their home winning streak to 18 and abruptly ended Indiana’s successful run.

Now, the pressure squarely is on the Pacers heading into Saturday’s Game 5 in Indianapolis, where they have won 12 straight.

“This is a test of our will,” forward Austin Croshere said. “We really haven’t faced any adversity yet, but we are facing it now. This is our wake-up call.”

The Pacers won an NBA-best 61 games during the regular season — the most in franchise history — then set a league record by winning six straight playoff games by double digits. The last two came against a Heat team that looked weary from a seven-game first-round series and overmatched against the deeper, more talented Pacers.

What a difference a beach makes.

“It’s a very new ballgame,” Heat forward Caron Butler said. “Now we’ve got to get a win on the road.”

The Pacers clearly were rattled by the resurgent Heat. In the closing moments of Wednesday’s Game 4 loss, Indiana point guard Jamaal Tinsley was ejected for a flagrant foul on Eddie Jones, and Ron Artest picked up another flagrant for a takedown of Wade.

“I sensed a little frustration on their part because they jumped out on us early and maybe felt they could have won the game,” Heat center Brian Grant said. “But we came back on them and down the stretch we weren’t going to back down.”

It’s an unfamiliar position for the Pacers, who have lost back-to-back games for just the fourth time this season. They have not lost three games in a row since April 2003.

“This is the first challenge we’ve had in two rounds,” Jermaine O’Neal said. “This is a new situation for us. We just need to play our game. I know the coaches are frustrated because they’ve done all they can do.”

The good news for Indiana is that O’Neal has broken out of his shooting slump. After going 10-for-32 in the first two games, O’Neal scored 66 points in the two in Miami, including 37 in Game 4.

But Tinsley says offense was never the concern against the Heat, who haven’t won on the road since beating New Orleans on Jan. 31.

“We’re getting enough points. We have find a way to stop people,” Tinsley said.
