CLEVELAND -- LeBron James shook off an atrocious shooting start and withstood Atlanta's gritty comeback to record a triple-double, and the Cleveland Cavaliers moved within one win of the NBA Finals by beating the Hawks 114-111 in overtime last night to take a 3-0 series lead.

James missed his first 10 shots, but finished with 37 points, 18 rebounds and 13 assists. The Cavs needed every single one of them to hold off the top-seeded Hawks, who fought Cleveland until the final seconds despite being without injured shooter Kyle Korver and losing Al Horford, who was ejected in the first half.

James hit a 3-pointer with 36.4 seconds left to put the Cavs ahead by one, and the superstar dropped a runner with 12.8 left to make it 114-111.

Atlanta had two chances to tie it in the final seconds, but Shelvin Mack missed two 3-pointers.

At the final horn, an exhausted James, who was favoring his right leg for most of overtime, dropped to the floor and had to be helped to his feet.

He'll have just one day to rest up before the Cavs try to earn their second Finals trip -- and the fifth in a row for James -- in Game 4 tomorrow night.
