James and Irving show

LOS ANGELES — Kyrie Irving and LeBron James combined for 76 points as the Cleveland Cavaliers battled to a 11299 victory over the Boston Celtics on Tuesday to move within one game of a place in the NBA Finals.

The win gives Cleveland a 3-1 lead in the best-of-seven series and leaves them firmly on track for a third consecutive NBA Finals showdown against the Golden State Warriors.

Cleveland, stunned by Boston in Game 3 after romping two blowout wins in the opening two games of the Eastern Conference series, looked to be heading for another shock as the Celtics dominated the first half.

Boston powered into a 2919 first quarter lead and maintained their 10-point cushion through to half-time, leading 57-47 at the break.

But as tension among Cleveland's home fans mounted at the Quicken Loans Arena, it was left to Irving to ride to the rescue with a sensational, momentumchanging display in the third quarter.

Irving piled on 21 points in the third period as Cleveland turned their 10-point half-time deficit into an 87-80 lead at the end of the third quarter. Irving eventually finished with 42 points.

"Coming out at half-time, I just wanted to be aggressive and lead my guys and leave it all out there on the floor," Irving said.

"We understand the goal out here and we want to accomplish something bigger than ourselves. It's going to take a full 48-minute game to do it."

James, determined to bounce back after a poor 11point haul in Game 3, then steadied the Cleveland nerves in the fourth quarter, bringing the Cavaliers home for the win as Boston's brave effort came up short.

James, who finished with 34 points, was joined in double figures by Kevin Love, who scored 17 points with 17 rebounds and five assists.

James, Irving and Love were the only three Cavs players to make double digits.

But it was Irving who was the undeniable star of the show for his spellbinding third quarter masterpiece that transformed the game.

"The kid is special," James said. "He was just waiting for an opportunity to blossom. I'm just happy and blessed that when I decided to come back that I was able to help him blossom.
