The Sydney Kings have won their sixth NBL title with a dramatic 113-101 overtime defeat of the Adelaide 36ers in the decisive fifth game of the championship series.

Superstar Kings guard Kendric Davis starred with 35 points and 14 assists in front of an all-time NBL record crowd of 18,589 fans in Sydney on Easter Sunday.

It was no surprise when Davis was named championship series MVP.

Bryce Cotton led the 36ers with 35 points of his own in the final chapter of his fiery tit-for-tat with rival point guard Davis that had defined the gripping series.

The Sixers took a seven-point lead into the final change and maintained their advantage until the last minute as they chased a fairytale first title since 2002.

But it was a two-point game when Davis slotted one under the basket in the final 30 seconds, before a Tim Soares tip-in tied the scores at 95-95 with six seconds remaining.

On the final possession of regulation time, Cotton drove to the basket but could not snatch victory for the Sixers with his last-second shot.

Davis set the tone, stealing from Cotton in the opening exchanges of overtime, before important 36ers big man Nick Rakocevic fouled out by grabbing Soares under the basket on the possession that followed.

The 36ers were on the back foot from there as frequent tormenter Davis added seven points in overtime.

When Makuach Maluach stole from Cotton and streaked away for a one-handed dunk in the final minute, the Kings had a game-high 13 point lead and were in sight of victory.

The win marks the Kings’ first championship since their legendary former coach Brian Goorjian returned with a mandate to revitalise the glamour club last season.

The Kings had been fancied to win the championship for much of the season, especially after a record-breaking 44-point game-one win this series.

But the 36ers clawed back to twice level the series, only to have their hearts broken on the biggest stage.
