The Thunder scored the first seven points and never looked back, going up by as much as 20 in the opening quarter on consecutive 3s by Martin.
Martin wound up hitting five of seven 3-point attempts in the first half and by halftime led all scorers with 22 points.
"We were just playing well as a team. The ball was just moving to me," Martin said. "I just played my normal game. If the shot's there, take it."
Although the Hornets appeared outclassed, they kept working, which seemed to get under the skin of some Thunder players.
Westbrook and Greivis Vasquez were assessed double technical fouls at the end of the half, and Durant and Kendrick Perkins walked toward halfcourt to have words with Hornets players including Davis. Monty Williams also strode toward center court and angrily told Durant and Perkins not to talk to his players.
The teams then headed to the locker rooms without further incident, and Hornets fans lustily booed Thunder players as they disappeared into the tunnel.
Westbrook said he had no idea what happened or why technicals were called. Williams said it was just a little misunderstanding.
"We thought they said something. They thought we said something. It happens," Williams said. ""When you have guys like Russell and Greivis out there competing like that, things will happen. We're men. But you also have to be man enough to admit that we do goofy things when we compete. ... So we were just out there kind of yelling back and forth. Basically they were just kicking our butts."
Notes: Hornets G Matt Carroll, acquired in a trade that sent Hakim Warrick to Charlotte on Tuesday, still has not reported to New Orleans, which has played twice since the deal. Hornets general manager Dell Demps stopped short of saying the Hornets intend to buy Carroll out, but said the player and team have an agreement that has excused Carroll from showing up for now. ... The Hornets announced earlier in the day a multiyear contract extension for Demps. ... The Thunder, who had lost its previous game Wednesday at Memphis, improved to 3-0 in games played after a loss. Last season Oklahoma City was 15-3 in games played after a loss.
