Irving leads way as Cavaliers take victory

BASKETBALL: A game-high 42 points from Australian-born Kyrie Irving has helped take the Cleveland Cavaliers to within one win of a third-straight NBA finals showdown with Golden State Warriors.

Irving scored 21 points in the third quarter at Quicken Loans Arena as the Cavaliers fought back from a 57-47 half-time deficit to defeat the Boston Celtics 112-99.

Cleveland now leads the series 3-1 with game five in Boston tomorrow morning (AEST).

LeBron James bounced back from only scoring 11 points in the game-three loss hitting 34 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."

Irving said Cleveland would benefit from having been put under pressure by Boston in game three.

"We need to hit adversity in order to grow," he said.

"The only thing that matters now is to get a win back in Boston."
