INDIANAPOLIS, May 15 (Ticker) -- Rasheed Wallace again proved himself correct when it came to making good on a guarantee.

Wallace and Chauncey Billups both had big games and the Detroit Pistons showed some resiliency of their own in a convincing 89-76 victory over the Indiana Pacers that evened their Eastern Conference semifinal at 2-2.

The defending champion Pistons cruised to a victory in the series opener, then dropped the last two games.

But Wallace had little doubt the Pistons would respond, saying after Game 3, "We are definitely going back to Detroit with this thing 2-2, no question about it."

"It was answering the bell. We couldn't afford to go down 3-1 to this team," Wallace said.

"Rasheed would be the first to say that his team backed him up," Pistons coach Larry Brown said. "He's a great teammate and was taking all the blame for us losing after Games 2 and 3."

Wallace issued a similar guarantee last season after Detroit lost the series opener to Indiana in the conference finals and his team responded with a 72-67 road win in Game 2.

"My first reaction was, I know he's going to bring his 'A' game when he does that," Pistons forward Tayshaun Prince said. "Obviously, when you make statements like that, you have to come ready to play. We knew he was going to be focused and ready to play and we just needed to be there with him. We knew we had to lay it all on the line for him."

The Pistons started making good on Wallace's promise pretty early. They used a 19-1 run in the first quarter to build a lead, then reeled off a 16-2 surge in the third quarter to take control for good.

Wallace also let his play do the talking as he had his best game of the series, collecting 17 points, 12 rebounds and five blocked shots.

Billups responded as well, scoring 29 points on 10-of-20 shooting. He had seven points in the spurt in the third quarter that ended with the Pistons holding a 72-56 advantage.

"That (Wallace's prediction) just gives us some extra incentive," Billups said. "We were going to play this hard and aggressive anyway. When he does that, he puts a lot of pressure on himself, and he seems to play better with the pressure on him. We knew as a team that we had to come out ready, because everyone was going to pinpoint the statement. I love it when he does that because I know he's going to come out and give it his all."

Antonio McDyess added 12 points off the bench for Detroit, which hosts Game 5 on Tuesday.

"This is a three-game series now," Billups said. "The pressure is not on them, they have nothing to lose. We are the kind of of team that plays best when under pressure."

After squandering a 14-point fourth-quarter lead in Game 3 before recovering, the Pacers struggled to find their offense in this one and shot just 37 percent (26-of-70) and made a woeful 3-of-19 3-pointers.

"Give Detroit a lot of credit, they really raised the level of their game," Pacers coach Rick Carlisle said. "We knew they would play a great game and they knew they would play their best, and they did."

Stephen Jackson scored 23 points to pace Indiana, which fell to 2-3 at home in the postseason. The Pacers are 4-2 on the road in the playoffs.

Wallace picked up a technical foul with 5:04 left in the third quarter after fouling Jermaine O'Neal. Reggie Miller hit the technical free throw and O'Neal made both of his foul shots, pulling the Pacers within 56-50.

But McDyess made a turnaround jumper and Billups scored seven points in under two minutes as the Pistons rebuilt the lead to double digits.

Billups' jumper at the 2:02 mark made it 67-52 before McDyess made two free throws and Tayshaun Prince a 3-pointer with 46 seconds left in the third quarter for a 72-52 bulge.

Billups also did the job defensively, helping harass Jamaal Tinsley into seven turnovers.

"I was looking to pass more and they kept deflecting them away," Tinsley said.

Richard Hamilton added 13 points and seven assists for the Pistons, who led by at least 12 points the entire fourth quarter. Detroit shot 41 percent (34-of-84) and made 18-of-20 free throws.

Like Billups, Hamilton also played a defensive role by helping hold the ageless veteran Miller to just seven points on 2-of-6 shooting. Miller missed all four of his 3-point attempts and is 0-of-11 from the arc in the last two games.

It also was a rough game for O'Neal, who scored 10 points on just 4-of-15 shooting.

"I just didn't make my shots tonight," O'Neal said. "Sometimes you have those nights, those games. And unfortunately for me, that was tonight. It's a cycle in basketball. I'm a a believer that you should not get too hot or too cold."

The Pacers carried some momentum over from the win in Game Three, building a 9-2 lead on Dale Davis' dunk with 9:16 left in the first quarter.

But the Pistons' defense took over from there. They held the Pacers without a basket for the next 7:36, held a 21-13 advantage after one quarter and led by as many as 17 points in the second quarter before setting for a 47-34 cushion the break.

The winner of the series will play the top-seeded Miami Heat in the conference finals. The Heat completed a sweep of the Washington Wizards on Saturday.
