Without reigning MVP Kevin Durant, Russell Westbrook starred with 21 points and a career-high 17 assists, 12 of which came in the first half, as the Thunder won their sixth game in a row.
In the day's early game, the Cleveland Cavaliers won for the 16th time in 18 matches with a convincing 101-83 triumph over the lowly New York Knicks.
LeBron James had 18 points, seven rebounds and seven assists, while Iman Shumpert and J.R. Smith impressed on their return to the Madison Square Garden after being traded to the Cavs last month.
There is no team left with a single-digit count in the loss column after the Golden State Warriors suffered their 10th defeat of the season at the Indiana Pacers.
The Warriors were without All-Star point-guard Stephen Curry for the first time this season and Klay Thompson picked up the slack with 39 points, but it wasn't enough as Rodney Stuckey's 39 led Indiana to the win.
With Golden State losing, the Atlanta Hawks closed in on the best record in the league by seeing off the Milwaukee Bucks 97-86, avoiding a first three-game losing streak of the season.
Paul Millsap starred for the Eastern Conference-leading Hawks with 23 points and 16 rebounds, while Giannis Antetokounmpo and Khris Middleton had 19 for the Bucks.

While Jackson's bow improved as the match went on, another point-guard saw his debut come to a sour end. Isaiah Thomas was ejected in the fourth quarter as the Boston Celtics fell to an overtime defeat against the Los Angeles Lakers.
