Klay Thompson scored 26 points on 11-for-18 shooting, and Andre Iguodala had 15 points while missing just one shot in his first action with the Warriors, who signed him to a four-year, $48 million deal in July.
Harrison Barnes and David Lee scored 10 points apiece, while Stephen Curry had five points in 14 quiet minutes.
