CHICAGO, May 4 (Ticker) -- Shaquille O'Neal showed up to show the Chicago Bulls the door.

O'Neal turned back the clock when he used to dominate on a nightly basis as the Miami Heat coasted into the Eastern Conference semifinals with a 113-96 victory over the Bulls in Game 6 of their first-round series.

A three-time NBA Finals MVP, the 7-1, 325-pound O'Neal finished with 30 points and 20 rebounds in his best game of the series for the second-seeded Heat.

"When I was in the game my guys were looking for me," O'Neal said. "I was getting the ball in the right spots, then I was able to get my shots and hit them."

Unlike Games 3 and 4 here when he battled foul trouble and combined for just 24 points and 12 rebounds, O'Neal had no trouble staying on the court Wednesday. The Bulls had no answers and were eliminated in the first round for a second straight year.

"If I'm on the court and I'm active that's how it's going to be most of the time," O'Neal said. "Games 2, 3, 4 and 5, I was in foul trouble. Tonight I wasn't in foul trouble so I could do what I do."

O'Neal toyed with the combination of Tyson Chandler and Mike Sweetney and made 13-of-24 shots in 38 minutes.

With O'Neal leading the way, the Heat - who lost both Games 3 and 4 - were in control from the outset. They never trailed and built a double-digit lead in the first quarter before settling for a 55-41 cushion at the half.

"I think we started the game extremely well," Heat coach Pat Riley said. "We weren't turning it over and we were scoring. They were missing a lot of shots. We came out and established ourselves, while they seemed a little bit tight in the beginning."

O'Neal had 14 points and 11 rebounds and Dwyane Wade scored 11 points in the first half, when the Heat shot 56 percent (20-of-36). Chicago shot a woeful 32 percent (12-of-38) in the first half and never were able to recover.

"The last two games we left the page of what we like to do," Bulls coach Scott Skiles said. "We hard a hard time reeling it back in, tonight I think they played their best game of the series."

Wade had little trouble with the bruised hip he suffered in Game 5 as he scored 23 points before fouling out and Udonis Haslem had 17 and 14 rebounds for Miami, which will meet third-seeded New Jersey in the conference semifinals. New Jersey won three of the four meetings between the teams during the regular season.

"Our coaches will have a great game plan put together," Wade said. "No matter where the games in the next series are played, at home or on the road they will be great games."

The Heat were in control the entire second half, although the Bulls got as close as 97-88 with 4:57 remaining on Ben Gordon's three-point play. But Haslem scored five straight points and James Posey had a steal and layup to help the Heat put away the game.

"At that point I hit the boards and got some offensive rebounds," Haslem said. "I was struggling early with my offense. In the second half I just tried to be much more aggressive."

Posey made five 3-pointers and scored 18 points for Miami, which had been 0-9 all-time at Chicago in the postseason.

"There was a lot of pressure on us this series," Riley said. "From what I hear not many people wanted us to win."

Kirk Hinrich scored 23 points, Gordon 21 and Andres Nocioni 20 for the Bulls, who shot 41 percent (31-of-75) and were outrebounded, 51-34.

"It's very disappointing not to advance," Hinrich said. "We had this series tied at 2-2, then for the most part we just had a couple of really rough games where we didn't play like ourselves."

"Some nights you make shots and some nights you don't," Gordon said. "Unfortunately the last two losses our backcourt had trouble making shots."
