The "ticked off" Sydney Kings charged through to their fifth NBL grand final in six years with a 109-77 drubbing of Perth in their deciding semi-final match at the Sydney Entertainment Centre.

Returning stars Mark Worthington and Jason Smith provided the early ammunition and the Kings' bench maintained the rage as Sydney meted out a humiliating thrashing to the Wildcats.

Sydney will host the first of the best-of-five-game grand final series against Melbourne on Wednesday as they bid for their fourth title in six seasons under coach Brian Goorjian.

Perth were held to a franchise-low 24 points in the first half during which they endured a nightmarish time at both ends of the court, trailing by 37 points at halftime.

The Wildcats shot at just 25 per cent from the field in the first half and were harassed into 13 turnovers.

West Australian-born forward Worthington, who missed game two after being suspended for striking Perth star Shawn Redhage in game one, played like a man possessed in the early stages.

Fired-up by losing Worthington last Wednesday and Perth forward Alex Loughton escaping a ban for using an elbow on Glen Saville in game two, the Kings radiated intensity and the Wildcats crumbled under the pressure.

Guard and skipper Smith, who missed the loss in Perth with a shoulder injury, and Worthington simply smothered the visitors.

The two men scored all the points in an early 12-0 run which turned a 4-2 lead for Perth into a 14-4 advantage to the Kings.

Redhage, who averaged 30 points across the first two games, finished with 20 but had a first half to forget.

He missed eight of 12 free-throws before halftime, but was still Perth's only offensive threat early on.

The only other Wildcat to notch a field goal in the first quarter was centre Paul Rogers.

Perth coach Scott Fisher's assertion that Sydney's depth was their biggest strength was borne out, as the Kings' bench outscored their counterparts by a massive 57-8.

Bench forward Russell Hinder had 17 points for the Kings and Isiah Victor added 19.

Guard Gerald Brown (23 points) and Rogers (14) were the only other Wildcats apart from Redhage to offer anything on offence.

Sydney's lead ballooned to as much as 50 early in the last quarter but Perth's offence improved enough to seem the past their franchise-low game score of 67.

It was a positive night all round for the Kings, with acting NBL chief executive Chuck Harmison saying he was very comfortable about Sydney's much-publicised financial situation after holding informal talks with majority shareholder Tim Johnston before Saturday night's game.
