Stephen Curry scored 40 points and Kevin Durant 34 to power a stunning second-half comeback that lifted Golden State over San Antonio 113-111 on Sunday in an NBA playoff thriller. The Spurs squandered a 25-point lead and might have lost star forward Kawhi Leonard, who left the game for good with a sprained left ankle early in the third quarter. Golden State seized a 1-0 edge in the best-of-seven Western Conference final, which continues Tuesday in Oakland.
