Adelaide 36ers held off a fast-finishing West Sydney Razorbacks to win a thrilling NBL clash 125-118 at the Distinctive Homes Dome.

The lead blew out to 22 points early in the second before Dann, Rush and Troy DeVries found some shooting form to keep the Razorbacks in the contest with a 72-59 halftime score.

But veteran Lanard Copeland helped the 36ers regain some composure only to see the Razorbacks again steal the momentum to trail 100-95 at three quartertime.

Rush levelled scores with a three-pointer then Ng and Ballinger steadied to see the 36ers home.
