Thompson finished 8 of 17 from the field coming off the bench behind Harrison Barnes in Golden State's exhibition home opener. Barnes missed all four shots he took and had one rebound in 6 disappointing minutes.
Both started every game they played last season. Warriors coach Mark Jackson is experimenting with lineups in the preseason after the team signed free agent Andre Iguodala to a four-year, $48 million deal this summer.
Stephen Curry scored 23 points and David Lee had 14 points and 13 rebounds to help the Warriors build a 16-point lead with 4:33 remaining. Iguodala finished with seven points, three assists and three rebounds in 32 minutes.
Isaiah Thomas had 15 points and six rebounds and DeMarcus Cousins added nine points and four rebounds for the Kings, who lost their first preseason game under new owner Vivek Ranadive and coach Mike Malone.
