ATLANTA — LeBron James scored 21 points, including the clinching jumper with 13.6 seconds remaining, and Miami knocked off the Atlanta Hawks 95-89 on Friday night for the Heat's fourth straight win. Jeff Teague hit consecutive 3-pointers as the Hawks rallied from a nine-point deficit in the fourth quarter. But Josh Smith, on an awful night, missed two free throws with just over a minute remaining, and James finished off Atlanta after the teams traded turnovers.
