Kevin Durant dazzled against his old team once again with a season-best 40 points, and the Golden State Warriors beat Oklahoma City 121-100 on Wednesday night despite Russell Westbrook’s 21st triple-double for the Thunder. Westbrook had 27 points, 15 rebounds and 13 assists in an improved showing from his 20-point outing on 4-for-15 shooting when OKC first faced Durant in the other jersey here 2 1/2 months ago and watched him dismantle the Thunder from every which way.
