In basketball's equivalent of a bare knuckled fight, the Pigs finally delivered the knockout punch.

They are now just one win away from securing their maiden championship after clinching an NBL grand final game three nailbiter at the Sydney Entertainment Centre.

The Pigs, who began the best-of-five series as rank underdogs, can wrap up an historic NBL title on their home court, the NSW State Sports Centre, in game four on Sunday.

West Sydney is licking its lips in anticipation of returning to "the Pig Pen" where it holds a perfect 8-0 finals record.

Not that the Pigs had it all their own way.

After Pigs forward Simon Dwight's layup went in and out of the basket, Kings guard CJ Brut on had a chance to cover himself in glory and win the match in the final seconds.

But his shot missed - to the dismay of the majority of the 8073-strong crowd - and the scores were locked up at 66-66 - the lowest regulation time score in NBL grand final history.

In the five minute overtime period, the Pigs looked to have the match when Brut on missed his potential match tying shot, but West Sydney swingman Sam Mackinnon lost the ball to - and fouled - Kings reserve Brad Sheridan.

However, Sheridan missed both foul shots that would have sent the game into double overtime, saving the Pigs' bacon.

It was another all-round team effort from the Pigs, Boomers guard John Rillie grabbing 18 points, Dwight - who had to pass a fitness test for his injured knee - grabbing 17 points and Aaron Trahair 15.
