With Tall Blacks utility Dion Prewster also doing a terrific jack-of-all-trades job for the Kings, Sydney's offence was flowing smoothly and providing quality looks to snare a 40-37 halftime advantage.
It was through strength rather than style that the Breakers kept themselves in touch.
The Breakers' usual high-octane offence was stuttering, with Webster cold to begin the game as the visitors went at a 35% shooting clip in the first half, including 1/12 from deep.
However, a massive 28-14 advantage on the glass saw many put-back layup opportunities for big men Charles Jackson and Alex Pledger, while Thomas Abercrombie also found himself dragging down several boards.
Just as the Breakers finally started to find their shooting stroke and offensive rhythm, injury struck - sending their star distributor to the bench in pain, having racked up 14 points, seven rebounds and seven dimes.
With the other Jackson - Charles - also hitting the bench due to foul trouble after a fine stint, the Breakers needed someone to step up, and found it in Webster and Bartlett whose crucial buckets secured the win.
Webster ended with 17 points on 7/23 shooting, Bartlett had 13 while Pledger (14 points, nine rebounds) and Abercrombie (11 points and a career-high 15 boards) all made significant impressions.
The Breakers now return home to take on Melbourne United on Sunday in a highly anticipated rematch of the clash which ended in a refereeing controversy earlier this month.
