It’s amazing how quickly a playoff series can turn. From decisively outplayed in two home contests, already facing what Manu Ginobili deemed to be must-win circumstances on the road in Game 3, the Spurs now have an opportunity to start shoveling dirt on the upstart Warriors today in Oakland with a potential 3-1 series advantage. They earned it with a 102-92 victory on Friday that could have scarcely gone much better for them. In addition to proving their veteran mettle by holding off one Warriors charge after another, the Spurs benefited from a sprained ankle that could sideline Golden State star Stephen Curry. He is listed a game-time decision. Curry was struggling even before that, shooting just 17 for 50 since his 22-point rampage in the third quarter of Game 1. Danny Green said the Spurs learned their lesson after that outburst, treating him like a “mini-Kevin Durant” over the past two contests. “Obviously he’s not as tall or as lethal attacking the rim,” Green told USA Today, “but he can finish, has floaters, has all types of stuff, a quick trigger. He’s one of the best scorers we have in the league now. “And for me to be able to guard him that tough – they have me guarding him and telling me to step up to this challenge – is big for me. Long story short, just stay connected to him. Stay in his airspace and try to make him uncomfortable.” Fellow sharpshooter Klay Thompson has gotten similar attention from Kawhi Leonard. As a result, he’s made only 9 of 28 attempts since staggering the Spurs with 29 points in the first half of Game 2.
