OAKLAND, Calif. — Kawhi Leonard and the San Antonio Spurs put on such a basketball show that they sent the loyal Golden State fans to a rare early exit. What a strange sight at Oracle Arena for opening night and Kevin Durant’s long-awaited Warriors debut.

Leonard scored a career-high 35 points and the Spurs emphatically spoiled Durant’s first game for Golden State in a 129-100 rout on Tuesday that the Warriors could hardly believe had just happened.

“We got punched in the mouth,” Draymond Green said. “I don’t know if it was quite a bad thing for us.”

Durant had 27 points and 10 rebounds, but little looked in sync for MVP Stephen Curry and the reigning Western Conference champions in a forgettable first game — and quite a different one after the Warriors dominated at home and came out of the blocks last season with a record 24-0 start.
