LeBron James and the other two members of Cleveland's 'Big Three' led the Cavaliers to a comfortable home victory over Boston in the opening game of their playoff series.

Guard Kyrie Irving scored 30 points in his post-season debut, sinking his first five three-pointers. Forward Kevin Love had 19 points and 12 rebounds and James added 20 points, seven assists and six rebounds.

Isaiah Thomas came off the bench to lead the Celtics with 22 points and 10 assists, while back-up centre Kelly Olynyk added 12 points.

"Having four days of preparation and being with my brothers in the war room going over film, going into the game, you feel prepared," Irving said. "I'm just glad I got Game One out of the way, all the nerves."

Sunday marked the Cavs' first playoff game in five years.
