Rudy Gay led the Spurs with 15 points off the bench. 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 here at Oracle Arena.
The Warriors looked unbeatable again. And that was without the do-everything Curry.
Golden State said all week that it was a new season, then went out and showed it. The Warriors have plans for nothing short of a repeat title.
“We’re a championship ball club,” Green said. “We know what it takes this time a year to win.”
He added: “We’re primed for this. A lot of people tend to forget what we’re capable of. We know.”
Golden State came with the kind of swarming defense it is so used to playing but hadn’t exhibited much lately as rotations were mixed and matched because of injuries and illness.
San Antonio couldn’t keep up from the opening tip.
“We were just very overly excited, overzealous,” San Antonio’s Danny Green said. “Overreacting to a lot of things because we are so excited that we’re in the playoffs and playing, obviously, the best team in the world.”
