New Zealand Breakers have made it an NBL championship three-peat, beating the Wildcats in game two of the grand final series in front of a sold out Perth Arena on Friday night.

The Breakers won the opening game in Auckland to basically have a free hit at winning the championship in front of 13,527 fans at the Perth Arena and they ground out a 70-66 victory in a contest that had virtually everything.

CJ Bruton was the star once again for the Breakers as he claimed his sixth NBL championship made up of two with the Sydney Kings, one with the Brisbane Bullets and now the three with the New Zealanders.

The Breakers are just the second club after the Kings to win three straight NBL championships.

Each time they faced the Wildcats in the grand final series and this was the first to be decided in two games.

Bruton top-scored with 16 points while hitting 4-of-5 from three-point territory.

Regular season and grand final MVP Cedric Jackson finished with 14 points, six rebounds, five assists and three steals.

Daryl Corletto hit 11 points with Alex Pledger finishing with eight points and seven boards, and Tom Abercrombie had just six points but grabbed 11 rebounds.

Kevin Lisch and Shawn Redhage had 14 points each for the Wildcats with Jesse Wagstaff adding 10 while Greg Hire pulled in 10 rebounds.

Bruton hit two big threes in the first quarter but the Wildcat hung in to just trail by a point at quarter-time and to level at half-time.

The Breakers took control early in the third quarter, holding the Wildcats scoreless for five minutes and opening up an 11-point lead.

The lead was still 11 by three quarter-time but the home side got back to within a point with 28 seconds to go following two free-throws from Hire.

Corletto then went to the line and hit one.

But Redhage missed a desperation shot and then Bruton calmly hit two free throws of his own and the Breakers won by four to claim the championship.
