Kevon Looney rushed his first try, not realizing he had a little time. Then he tipped in the game-winner as the final buzzer of the second overtime sounded. He got swarmed in celebration.

The durable big man who played every game last season and all of them so far in this one delivered a career-high 21 rebounds with two in the final 2 seconds, Klay Thompson scored a season-best 54 points, and the Golden State Warriors held off the Atlanta Hawks 143-141 on Monday night.

Looney laughed when asked if he had ever scored the game-winning basket — “not a walkoff game-winner.”

“I rushed the first one I didn’t think I had that much time, but I saw I had more time so I took my time on the second one and I was able to make it,” Looney said.

Trae Young tied the score on a floating layup with 8.2 seconds remaining before the Warriors’ final chance. Young made four crucial free throws late in the first OT and finished with 30 points and 14 assists.
