With his big-game swagger on display for the world and that signature mouthpiece dangling from a celebratory grin, Stephen Curry drove fearlessly to the basket with jaw-dropping acrobatics all afternoon and he fired with precision from way back in a Game 7 extravaganza for the ages.

He even playfully pretended to push the button and Light the Beam, Sacramento-style.

Curry scored a playoff career-high 50 points in the most prolific Game 7 performance ever and answered time and again to will the Warriors on in their quest for a repeat, sending Golden State into the Western Conference semifinals with a 120-100 win against the Sacramento Kings in Sunday’s winner-take-all Game 7.

Curry led a memorable comeback in the series, too, perhaps improbable even for the defending champions when they got down 2-0 and given their road woes all season.

“It’s amazing ’cuz you’re still in the fight,” Curry said. “Better than the alternative of on the outside looking in. Having been down 0-2 in this series, nothing was guaranteed, you don’t take anything for granted.”

“For Steph to be the first player ever to get 50 in a Game 7, he’s sublime,” coach Steve Kerr said.

Kevon Looney grabbed 21 rebounds for a Warriors team that needed to win twice on the road facing a hostile, cowbell-clanging crowd in the state capital to become the first reigning champion to drop the first two games and win any postseason series.

Now, bring on LeBron James and the Los Angeles Lakers in the Western Conference semifinals with all that NBA Finals history between James and Golden State dating to his Cleveland days. Game 1 is Tuesday night at Chase Center.
