Westbrook set the tone in the second overtime, stealing the ball on Minnesota's opening possession and racing to the other end for a layup that resulted in a three-point play.
The Thunder never trailed in the period and put it away with nine straight points after Nick Collison blocked Love's shot that would have tied it at 140.
Love, who beat Durant in the 3-Point Contest on All-Star weekend, made a career-high seven 3s and also pulled down 14 rebounds while becoming the third player to eclipse 50 points this season.

76ERS 99, CELTICS 86
PHILADELPHIA (AP) — Elton Brand scored 20 points, and Spencer Hawes had 12 points and 10 rebounds to help Philadelphia remain in first place in the Atlantic Division.
The Celtics would have grabbed first with a win, knocking out a Sixers team that has held that spot for all but a few days this season. The Sixers outscored Boston by 20 points in the third quarter to take control.
There was a serious scare when Celtics guard Mickael Pietrus left on a stretcher and was hospitalized after an awkward collision late in the first half.

He instantly clutched the back of his head with both hands and rolled over on his side.
