The Toronto Raptors withstood a 51-point performance from Kevin Durant to beat two-time defending champions Golden State 131-128 in overtime Thursday in a game billed as a possible NBA Finals preview. Kawhi Leonard scored 37 points and Pascal Siakam added a career high 26 for the Raptors, who notched a seventh straight victory to improve their league-leading record to 19-4 in front of a jubilant home crowd. "It's a building block for us," Leonard said.
