Prank the NBA, of course.

NBA star Klay Thompson found himself with a twin on the sidelines during his Golden State Warriors match against the Houston Rockets this afternoon (AEDT).

The 27-year-old’s freakish doppelganger was apparently so good he was able to snag a high-five off NBA heavyweight Kevin Durant.

The prankster’s identity was later revealed as BigDawsTV, a Youtuber with nearly 3 million subscribers.

“You know, I came out of the gates smoking and hit a couple of three’s right away. I was really feeling myself (but) I missed a couple out there but I think it’s because I hurt my hand. Anyway, I came out hot in the second half and we’re gonna make things happen,” he said in a mock first half speech posted to Twitter.

It’s not the first time the Youtuber has pulled off the cheeky stunt. The 23-year-old internet star posted a video to his channel detailing his lengthy transformation into the Warriors guard before heading to Game 5 of the NBA Finals earlier this year.

WARRIORS ROCKED BY PLUCKY ROCKETS

Kevin Durant’s baseline jumper swished through the net just barely too late, and the Houston Rockets rallied in the fourth to beat Golden State 122-121 Tuesday on the night the Warriors received their championship rings.

The Warriors had one last chance with 10.6 seconds left and Durant came up with the ball after Stephen Curry had missed. Durant and the Warriors thought they’d won and confetti began to fall when the two remaining officials — the third got hurt in the fourth quarter — reviewed the play and said Durant’s shot was after the buzzer.

Trevor Ariza’s 3-pointer with 2:09 remaining pulled Houston within 119-118 then Patrick McCaw hit a baseline jumper immediately after Golden State’s time-out. James Harden made a layup and PJ Tucker hit two free throws with 44.1 to make it 122-121.

Nick Young came off the bench to hit six 3-pointers and score 23 points in a brilliant Warriors debut, Curry scored 22 points and Durant had 20 after a slow start. Klay Thompson added 16 points.

Draymond Green was forced from the court with a worrying knee injury.

Chris Paul had four points on 2-for-9 shooting in his Rockets debut, while Harden scored 27 points and Eric Gordon 24 for the Rockets. Houston opened the fourth with a 9-0 run to get back in it.

The Warriors found their rhythm early but couldn’t close it out after an abbreviated preseason in terms of practice time given their recent trip to China for a pair of games against Minnesota.

Still, this opener was a far cry for the forgettable 129-100 defeat at home to San Antonio in Durant’s Warriors debut a year ago when Golden State came off a record 73-win season and runner-up finish to Cleveland in the 2016 Finals. “I just remember the last game of the season we played,” Durant said of the Game 5 Finals clincher in June.
