Chicago Bulls forward Tyrus Thomas, top, tumbles over Detroit guard Chauncey Billups while chasing a loose ball. The Pistons won, 108-87, to take a 2-0 lead in their playoff series Monday in Auburn Hills, Mich.

Auburn Hills, Mich. ? With two blowouts, the Detroit Pistons have turned Chicago’s first-round sweep over the defending NBA champions into a distant memory.

Tayshaun Prince scored 25 points to lead Detroit to a 108-87 victory Monday night and a 2-0 lead in the Eastern Conference semifinals.

The Bulls came into the series full of bravado – Andres Nocioni even predicted they would advance – after eliminating Miami in the first round.

Quickly, their tune has changed.

“We kind of lost our swagger,” said Kirk Hinrich, who didn’t make a shot in Game 2. “We need to get our swagger back.”

Game 3 will be Thursday in Chicago, giving the Bulls time to regroup after losing two games by a combined 47 points.

If the Pistons maintain their determined ways, however, it might not matter what Chicago does to adjust.

Detroit is 6-0 in the playoffs, its best winning streak in a postseason since closing the 1989 championship run with seven straight wins.

The Pistons are playing as they did in 2004, when they won a title with strong play at both ends of the court.

“We haven’t had this level of focus in a while,” Prince said. “But now that we are going on the road, it’s going to be a lot tougher.

“We haven’t done anything. We’ve just held serve.”

Richard Hamilton had 24 points, Chris Webber scored 22, and Chauncey Billups had 14 points and 10 assists.

Rasheed Wallace added 10 points.

Prince made nine of 20 shots, including three three-pointers, several mid-range shots and a dunk in traffic.

“He can take over games, especially when they try to focus on taking guys like Rip or Rasheed away,” Billups said.

Prince also slowed Luol Deng again, holding him to 16 points on 4-of-12 shooting. Deng scored 18 points on 16 shots in Game 1 after averaging 26.3 points in the first-round sweep over the Heat.

Chicago’s Tyrus Thomas scored 12 of his 18 points in the final quarter to prevent the Pistons from winning by 26, as they did in the series opener, but the Bulls’ stars did not shine.

Ben Gordon and Ben Wallace each scored 13 and Hinrich was held to two points on 0-for-7 shooting. Nocioni added 12 points.

Just as it did in Game 1, Detroit took control with a big run in the first quarter and prevented the Bulls from rallying the rest of the way.

“The thing that is the most surprising is that, in both games, we haven’t been very competitive,” Chicago coach Scott Skiles said. “Right from the jump ball, they’ve owned us.”

The Pistons led by 24 points early in the second quarter, 23 late in the third and had inside-and-out answers after Thomas helped Chicago pull to 93-80 midway through the fourth.

Rasheed Wallace dunked on Thomas and Billups made a three-pointer to dash the Bulls’ hopes.

The Bulls made just 23 field goals, matching the playoff franchise low they set in Game 1, and hit just over one-third of their shots.
