Miami, FL (Sports Network) - Make it two in a row for LeBron James and the Miami Heat. James completed a brilliant 37-point, 12-rebound effort with a clutch jumper and a pair of free throws as Miami secured a second straight championship with a 95-88 victory over the San Antonio Spurs in Game 7 of the NBA Finals. After an up-and-down first six games of the series, Dwyane Wade showed his true colors by also posting an impressive double-double with 23 points and 10 rebounds. Chris Bosh, the last member of Miami's Big Three, was held scoreless, but the Heat received an unexpected 18 points off the bench from Shane Battier, who iced the Spurs with six 3-pointers. Miami hit on 12 triples for the contest, twice as many as San Antonio connected on. The Spurs' Danny Green, who set a record for 3-pointers made in an NBA Finals during this series, was 2-for-19 from that distance combined over the last two games. Tim Duncan came through with 24 points and 12 rebounds, but missed a point-blank layup for San Antonio with under a minute left that would have tied the game. The 21-year-old Kawhi Leonard posted 19 points and 16 rebounds, but the Spurs trailed the entire fourth quarter and seemed out of gas at times following the team's late collapse in Game 6. It's the first loss in an NBA Finals for San Antonio, which had won in its first four trips. Tony Parker, slowed by a hamstring injury the last four games, had 10 points and was held scoreless in the second half.
