Shai Gilgeous-Alexander joined Oklahoma City in 2019.
Shai Gilgeous-Alexander delivered the decisive baskets deep into double overtime as the Oklahoma City Thunder opened their NBA title defense with a 125-124 win over the visiting Rockets.
The reigning MVP scored 35 points, featuring two from the free-throw line with just 2.3 seconds left in double OT, giving the titleholders a positive start.
The Rockets' big man led all scorers with 39 points and also hit a career-high five three-pointers.
But Chet Holmgren, who contributed 28 points, was instrumental alongside match-winner Gilgeous-Alexander.
"Determination and defense," Gilgeous-Alexander said of their showing. "We know that when we execute on defence we give ourselves a chance no matter what's going on—shots, missed attempts, fortune or bad luck. We did sufficient defensive work to secure the victory. We're pretty rusty, but it's a positive beginning."
Prior to the tip-off, the team's title banner was raised at their arena, while the squad were presented with their title rings.
Oklahoma City beat the Indiana Pacers in last season's championship series. It was their first title since the team relocated in 2008 to OKC from Seattle, who had won the 1979 title.
The Pacers will have the chance to secure some payback on Friday when they face the Thunder, while the Rockets return to action on the same day at the Pistons.
Elsewhere, a huge performance of 43 points, 12 boards and nine dimes from Luka Doncic was not enough to prevent his current team the Los Angeles Lakers from suffering a 119-109 loss against the Warriors.
Miami's star picked up 31 points and Golden State's sharpshooter chipped in 23 points for the visiting Warriors.
The Lakers were missing the league's top scorer James as he is recovering from sciatica.
