AUBURN HILLS, Mich., May 7 (Ticker) -- Tayshaun Prince's defensive assignment did nothing to slow down his offensive game.

Prince scored 16 of his 24 points in a blistering first half as the Detroit Pistons coasted to a 113-86 victory over the weary Cleveland Cavaliers in the opener of the Eastern Conference semifinals.

Richard Hamilton added 20 points and Chauncey Billups 14 and 10 assists for the top-seeded Pistons, who put on an offensive clinic in looking very much like the NBA's best team.

"We got our behinds kicked," Cleveland coach Mike Brown said. "I'll tell you what, they shot the heck out of the ball. They jumped on us early. This team already has a lot of confidence and when they go on runs like that at the end of the quarters, they tend to pounce on you. They played a (heck) of a ballgame."

The lanky 6-9 Prince will be the primary defender on 21-year-old phenom LeBron James, who averaged 30.7 points in leading the fourth-seeded Cavs by the fifth-seeded Washington Wizards in six games in the first round. James finished second in the NBA MVP voting to Steve Nash earlier Sunday.

Prince was the offensive leader in the first half, when the Pistons took all the drama out of this one.

Behind Prince, the Pistons shot 65 percent (24-of-37) and made 10-of-11 attempts from 3-point range in the first half en route to building a commanding 69-48 lead.

The Pistons, who scored a franchise-record 43 points in the second quarter, led by as many as 37 points in the second half.

"Tay was great because I think it's important to make LeBron work," Hamilton said. "They depend on him so much on the offensive end, you've got to make him work on the defensive end, too. Tay did an excellent job of doing that."

Detroit shot 52 percent (42-of-81) overall and went 15-of-22 from the arc.

"We just shot the ball great," Billups said. "When we can shoot it that good, nobody can really beat us. If any team shoots it that good, you're in trouble."

Playing less than 48 hours after closing their series against the Wizards, the Cavs held a 12-7 lead less than four minutes into the contest before the rested Pistons took control.

Billups, who finished fifth in MVP voting earlier in the day, scored nine points in a 19-4 surge over the last 8:15 of the first quarter that gave the Pistons a 26-16 lead. The lead only grew larger thereafter.

Prince and Lindsey Hunter nailed 3-pointers and Antonio McDyess drained a jumper to push the advantage to 56-39 with 2:36 left in the half. Hunter also drilled two long shots from the arc in the final minute of the half.

The Pistons' advantage grew to 94-63 after three quarters.

"We definitely know that we aren't going to shoot like this throughout the playoffs, but we knew we had to set a tone today," Prince said.

McDyess and Hunter scored 12 points apiece for Detroit, which had been off since Wednesday after disposing of Milwaukee in five games in the first round. The Pistons closed that series with a 122-93 destruction.

"Lindsey has always been known for his ability to defend, but he, along with all of our bench players, have shot the ball extremely well these first six games of the playoffs," Detroit coach Flip Saunders said.

James scored all 22 of his points in the first half for the Cavs, who are in the conference semifinals for the first time in 13 years. The superstar did not play the fourth quarter with the game out of reach.

"It wasn't frustrating, it was a bit discouraging," James said. "You play defense for 22 or 23 seconds and a guy hits a three at the end of the shot clock. But give much credit to the Pistons. They came out, took care of business on their home court and that's what it's about."

Game 2 is here Tuesday.
