LeBron James poured in 32 points to help the Cleveland Cavaliers beat the Boston Celtics 74-69 and force a deciding Game Seven in their Eastern Conference semi-final.

James also registered 12 rebounds and six assists as the Cavs delivered an impressive performance on home court to level the best-of-seven series at 3-3.

Kevin Garnett was top scorer for Boston with 25 points and eight rebounds while Paul Pierce contributed 16 points.

The Cavaliers led 59-50 going into the fourth quarter but had to weather a late rally by the conference's top-seeded Celtics.

Cleveland's victory sets up a series decider in Boston on Sunday. The home team has won every game in the series.

"We feel good but it's just one game," James said. "We had a game tonight where we could have gone down and it would have been over.

"It was a long game and we're going to let our hair down and then go into Boston and try to steal this one."
