OKLAHOMA CITY — Kevin Durant showed LeBron James how to play the fourth quarter in the NBA Finals. Durant scored 17 of his 36 points in another nightmarish final period for James and his team, leading a Thunder storm that overwhelmed the Heat and gave Oklahoma City a 105-94 victory over Miami in Game 1 on Tuesday night. Teaming with Russell Westbrook to outscore the Heat in the second half by themselves, Durant struck first in his head-to-head matchup with James, who had seven points in the final quarter and was helpless to stop the league's three-time scoring champion.
