INDIANAPOLIS, May 8 (Ticker) -- Indiana Pacers guards Reggie Miller and Jamaal Tinsley have the Miami Heat worried about a whole lot more than Jermaine O'Neal.

Miller scored 19 points and Tinsley handed out nine assists as the Pacers rolled an NBA playoff-record sixth straight double-digit win, a 91-80 victory over the Heat.

Top-seeded Indiana remained unbeaten in the postseason, opening a 2-0 lead over Miami in the Eastern Conference Semifinals. The Pacers have won their six playoff games by an average of 15.2 points.

When this series began, the fourth-seeded Heat appeared to be overmatched up front primarily due to the presence of O'Neal, an All-Star power forward who finished third in NBA MVP voting. While limiting O'Neal to 10-of-32 shooting with double-teams, Miami has allowed his teammates to get loose.

"It's the same old problem," Heat coach Stan Van Gundy said. "We competed. We worked hard inside ... They just have so many weapons. It's tough."

On Saturday, it was Miller who was a point-per-minute man. In 19 minutes, Indiana's elder statesman made 6-of-10 shots, including 3-of-6 from the arc.

"This team has evolved to accept their roles," said Miller, the franchise leader in virtually every category. "There will be nights where guys struggle offensively and others have to step up. We have depth; that's what makes us tough to play against."

"He's very capable and has a lot left in the tank," Pacers coach Rick Carlisle said.

Many of Miller's open looks came on deliveries from Tinsley, who played a virtually flawless floor game. He missed his only shot but did not commit a turnover and made three steals.

"Jamaal Tinsley played as good a game as he's played all year," Carlisle said. "He had a lot to do with getting the ball to the right people."

Ron Artest scored 20 points and O'Neal added 17 and nine rebounds for the Pacers, who got 34 points from their much deeper bench.

While Indiana seemed to have an endless supply of players, Miami was harnessed by foul trouble. The game got away from the Heat when Brian Grant and rookie Dwyane Wade had to sit down in the second quarter and again after Lamar Odom picked up his fourth foul in the third period.

Game 3 is Monday at Miami, where the Heat have won 16 straight games. However, Indiana won its only visit to American Airlines Arena during the season and has beaten Miami 11 straight times.

"We are a good road team and we know we will play well in Miami," O'Neal said.

The Pacers broke the record for consecutive double-digit wins shared by four other teams, including this year's Detroit Pistons, who can tie the mark Sunday.

Miami trailed just 31-29 when Grant - its best big man - sat down with his third foul at the 6:04 mark of the second period. Wade went to the bench with his third just over two minutes later.

Miller scored 11 points in the first half, including a rainbow 3-pointer at the horn for a 44-36 lead. He had two more 3-pointers around a runner early in the third period, extending the advantage to 55-46 at the 7:25 mark.

"It's not a coincidence he hits big shot after big shot," Van Gundy said. "There's nobody in the league who works harder on his shooting and game preparation than Reggie Miller."

A 3-pointer by Fred Jones, Miller's backup, made it 67-52 late in the period. The bench pushed the lead to 77-57 early in the fourth quarter.

Anthony Johnson scored nine points and fellow reserves Jones and Al Harrington added eight apiece. Harrington was a demon, grabbing nine rebounds and drawing three offensive fouls on the Heat.

Odom and Wade scored 19 points each for Miami.
