Thunder Launch Championship Defense with Nail-Biting Double Overtime Win

Shai Gilgeous-Alexander delivered the winning baskets deep into a second overtime period as the defending champions opened their NBA title defense with a 125-124 victory over the Houston Rockets.

Last season's MVP poured in 35 points, featuring two clutch free throws with just mere seconds remaining in double OT, giving the champions a positive start.

Houston's Alperun Sengun led all scorers with a game-high 39 and also hit a personal-best five shots from beyond the arc.

But the Thunder's rookie, who contributed 28 points of his own, was instrumental alongside the game's hero.

"Determination and defense," Gilgeous-Alexander commented of their showing. "We know that when we do it on defence we give ourselves a chance no matter what's going on—makes, misses, fortune or bad luck. We did enough defensive work to secure the victory. We're still shaking off rust, but it's a positive beginning."

Before the tip-off, Oklahoma's championship banner was unveiled at their home court, while the players were presented with their championship rings.

The Thunder defeated the Indiana Pacers in the previous season's best-of-seven NBA Finals. It was their maiden championship since the franchise moved in 2008 to Oklahoma City from Seattle, who had claimed the 1979 title.

Indiana will have the chance to secure some early revenge on this Friday when they host the Thunder, while the Rockets return to action on the identical day at the Pistons.

In other action, a huge effort of 43 points, 12 rebounds and nine assists from the Slovenian star was insufficient to prevent his new team the Los Angeles Lakers from suffering a 119-109 loss against the Warriors.

Miami's star scored 31 points and Golden State's sharpshooter added 23 for the visiting Warriors.

Los Angeles were missing the league's top scorer James as he recovers from a back issue.
