OAKLAND, Calif. — The Golden State Warriors had something to prove all right: Oh yes, they plan to stay on top in these playoffs despite a disappointing finish to the regular season.

Kevin Durant helped the defending champions get defensive in a hurry, finishing with 24 points, eight rebounds and seven assists and the Warriors returned to their old dominant selves at playoff time to beat the cold-shooting San Antonio Spurs 113-92 on Saturday.

“Absolutely,” Klay Thompson said about playing a memorable, statement-making Game 1. “We did not end the season on a high note, we kind of hobbled into the playoffs. We know how talented we are. We know how good we are. We have been here before in the postseason and know what it takes to win.”

And they still know how to win in impressive fashion on the NBA’s big stage.

Durant, Thompson and Draymond Green took charge in Game 1 of the first-round series to elevate the Warriors’ intensity at last playing without fellow All-Star and injured two-time MVP Stephen Curry, sidelined since March 23 with a sprained left knee.

Thompson found his shooting touch and scored 27 points, making 11 of 13 shots, while 7-footer JaVale McGee started in Steve Kerr’s center-by-committee approach and contributed 15 points, four rebounds and two blocked shots in 16 minutes. Green contributed 12 points, 11 assists and eight rebounds.

Rudy Gay led the Spurs with 15 points off the bench as leading scorer LaMarcus Aldridge was limited to 14 points on 5-for-12 shooting.

“The first quarter we looked like deer in the headlights,” Spurs coach Gregg Popovich said.

Game 2 in the best-of-seven series is Monday night at Oracle Arena.
