ATLANTA -- Forget the Big Three.

One is enough for the Cleveland Cavaliers, as long as it's the king.

LeBron James scored 30 points, and the Cavaliers took command of the Eastern Conference finals, even without injured star Kyrie Irving, by beating the Atlanta Hawks 94-82 on Friday night to take a 2-0 lead with the series heading to Ohio.

Cleveland pulled away with a dominating third quarter. James scored 11 points, the Hawks shot just 32 percent (7-of-22), and Cleveland led by as many as 20.

This was a blowout in every sense of the word.

The final margin, with a bunch of backups on the court, was as close as the Hawks had been since midway through the third.

"You really can't make me do what I don't want to do," James said. "I play the right way."

He'll get no argument from the Hawks.

Irving was scratched before the game because of an ailing left knee. Even so, the Cavaliers cruised to their second straight win in Atlanta.

James assumed many of the ball-handling duties and took advantage of Atlanta's DeMarre Carroll being less than 100 percent. Carroll started after being carried off the court two nights earlier, but he hardly looked like the "Junkyard Dog."

He wasn't the only one struggling. The Hawks were totally outclassed in one of the few times all season that has happened.

"In the playoffs, it takes more," Atlanta coach Mike Budenholzer said. "It takes better execution, better screening. You've got to do things harder."

The Cavaliers can wrap up the best-of-seven series simply by winning at home. The next two are in Cleveland, beginning with Game 3 on Sunday night.

This is why James returned home after spending four years in south Florida and leading the Heat to a pair of NBA titles. The Cavaliers, who have never won a championship, assembled a Miami-like Big Three with James, Irving and Kevin Love, but James is carrying the load, with Irving sidelined and Love out with a season-ending injury.

"How much does it help to have LeBron on your team?" Cleveland coach David Blatt said, repeating a question incredulously. "Do I really have to answer that?"

Nope.

To be fair, James had a bit of help. Tristan Thompson was a beast on the inside, as he grabbed 16 rebounds to spark Cleveland to a 47-39 advantage.

When Thompson dunked off a pass from James with less than five minutes remaining, the Cavaliers led 93-74, and many Atlanta fans began heading for the exits, surely feeling they had seen their team for the last time this season. Atlanta won a franchise-record 60 games to claim the top seed in the East, but the Hawks have been picked apart by James, who also had 31 points in Game 1.

The Hawks had hoped Carroll's appearance would provide an emotional boost. An injury that looked much more serious turned out to be only a sprain, and he drew a big cheer from the crowd when he did his customary sprint across the court during the opening introductions.

But at less than full speed, Carroll had no chance of guarding James, who made 10 of 22 shots, including a pair of 3-pointers. When the Hawks began collapsing toward the lane in an attempt to help Carroll, James always seemed to find the open man -- often lurking behind the 3-point stripe.

James had 11 assists and just missed a triple-double, with nine rebounds.

The Cavaliers finished 12-of-30 beyond the arc. Iman Shumpert knocked down four from long range and finished with 16 points.

Dennis Schroder led the Hawks with just 13 points. Carroll played a team-high 33:47 but managed only six points -- 10 fewer than his playoff average.

Carroll wasn't the only one hurting. Kyle Korver rolled his right ankle while going for a loose ball late in the third quarter, and he didn't return. Al Horford banged his knee early in the fourth and hobbled to the sideline, though he was able to come back.

It didn't really matter.

THE KING'S MILESTONES

James recorded his 74th 30-point playoff game, which tied him with Jerry West for fourth on the career all-time list.

The only players with more 30-point playoff games are Michael Jordan (109), Kobe Bryant (88) and Kareem Abdul-Jabbar (75).

HAPPY BIRTHDAY

Blatt celebrated his 56th birthday Friday. When asked during the morning shootaround what he wanted, the first-year coach gave the obvious reply: "Just a Cavs win. That's all I'm asking for."

He got his wish.
