CLEVELAND — LeBron James made a new guarantee: Game 6.

With Cleveland's wondrous season on the line, James had 37 points, 14 rebounds and 12 assists, and Mo Williams, who boldly predicted his team would come back and win this tight-as-can-be series, added 24 points in the Cavaliers' 112-102 victory over the Orlando Magic in Game 5 tonight.

It's back to Florida for Game 6 on Saturday night at amped-up Amway Arena.

You expected anything else?

"I mean this was a big game for us," James said. "You never want to disappoint the home crowd by not coming out and play as hard as you can. It was win or go home."

The Magic overcame a 22-point deficit but missed their first opportunity to close out the Cavaliers, who are trying to become just the ninth team since 1947 to rally and win a series after being down 3-1. Orlando will have two more tries to reach the NBA finals for the first time since 1995.

For Cleveland, a city banking on James to deliver a championship after a 45-year drought, the MVP was again in a league of his own.

James scored 21 points in the second half — 17 in the fourth quarter — and had a hand in 29 of Cleveland's 34 points in the final 12 minutes.

Hedo Turkoglu scored 29 to lead Orlando, and Dwight Howard had 24 and 10 rebounds before fouling out with 2:22 remaining when he was called for his sixth personal foul while trying to stop James on a drive.

Not even Superman was denying James.
