OAKLAND, Calif. — His spirits down, his left ankle limp and his team’s season hanging in the balance, Stephen Curry wondered whether he could recover for the biggest game of his career until a text message popped up on his phone around 2 a.m. Saturday.Curry called back his mother, Sonya, and vented his frustrations about his latest, and most inopportune, injury setback. Finally, she spoke up to calm his concerns.“She just reminded me and battled tested me to rely on my teammates and support,” Curry said.What followed was a Mother’s Day masterpiece.Curry scored 22 points to go with six rebounds and four assists on a bum ankle, rallying the Golden State Warriors past the San Antonio Spurs 97-87 in overtime Sunday to even the Western Conference semifinal at two games apiece.“It seems like every time you get on a roll and feel somewhat healthy there’s a setback,” said Curry, who shot 7 of 15 from the floor, including 5 of 10 from 3-point range. “And it just tests you. It changes your routine. It changes your outlook on the game, your preparation. You’ve got to deal with the injury and the adjustments you’re making as a team.”Golden State erased an eight-point deficit in the final five minutes of regulation. The Warriors scored the first nine points of overtime to whip the yellow-shirt wearing crowd of 19,596 into a frenzy and give this topsy-turvy series yet another twist.Tony Parker, wearing a black sleeve around his bruised left calf, scored 17 points on 6-of-17 shooting but never broke free the way he did in scoring 32 points the previous contest, saying the injury limited his ability to elevate.Manu Ginobili had 21 points and Tim Duncan added 19 points and 15 rebounds as the Spurs ran out of steam in the end.“We put ourselves in a position to win the game and it’s frustrating because we feel like we gave it away,” Duncan said.Golden State outrebounded the Spurs 65-51.“They did a good job in overtime. Just as simple as that,” Spurs coach Gregg Popovich said.
