By Rory Carroll OAKLAND, Calif. - LeBron James powered the sharpshooting Cleveland Cavaliers to a season-saving 112-97 win over the defending champion Golden State Warriors on Monday to climb within 3-2 in the best-of-seven NBA Finals. Cleveland, facing elimination at the hands of the top-seeded Warriors, got 41 points each from James and Kyrie Irving and displayed a tenacious defense to set up another do-or-die game for the Cavaliers on Thursday in Cleveland.
