Josh Giddey has won bragging rights over Australian countrymen Duop Reath and Matisse Thybulle as Oklahoma City belted Portland by 43 points for their biggest win in a decade.
One of the NBA's most potent attacking sides, the Thunder began Monday's (AEDT) road game with an 11-2 run and never again trailed, finishing up 134-91 winners.
Only twice since the turn of the century have the Thunder, or predecessors the Seattle Supersonics, scored bigger victories - both were by 45 points in 2012 and 2013.
