Once the lead swelled to 14, Kevin Durant waved both arms like a boxing referee stopping a fight. Durant scored 32 points, Stephen Curry added 23 and Golden State extended its road winning streak to 13 with a 118-108 Martin Luther King holiday victory Monday night over the Cleveland Cavaliers, their struggling NBA Finals foes. Durant scored 16 in the third quarter for the defending champions, who clamped down on defense and pulled away in the fourth to remain unbeaten outside Oracle Arena since Nov. 22.
