OKLAHOMA CITY (AP) — Shai Gilgeous-Alexander scored 31 points, Josh Giddey had a triple-double and the Oklahoma City Thunder rolled past the Portland Trail Blazers 139-77 on Thursday night, a 62-point victory that matched the fifthlargest rout in NBA history. “It was almost like a perfect storm, to be honest with you,” Portland coach Chauncey Billups said. “Nothing really worked for us.”
