Heat 110, Cavaliers 108: Ray Allen hit a go-ahead 3-pointer with 18 seconds left and LeBron James scored 30 points against his former team as host Miami came from behind to edge Cleveland.

Chris Bosh collected 23 points and seven rebounds, Dwyane Wade added 18 points and Allen scored 17 off the bench for the Heat, who have won four straight.

Dion Waiters and Jeremy Pargo scored 16 points apiece to lead eight scorers in double figures for the Cavaliers, who fell to 1-8 on the road and allowed at least 100 points for the 10th time in 13 games.

Cleveland led by as many as eight points in the fourth quarter and held a 108-101 advantage with 1:58 left after Daniel Gibson capped a 7-0 run with a 3-pointer. But James responded with a driving layup and Bosh blocked a shot on the other end that Allen grabbed and took all the way for the bucket and a foul, cutting it to 108-106.

Gibson and Anderson Varejao both missed jumpers at the other end and Miami made the most of its final possessions. James fed Allen for the go-ahead 3-pointer and Wade blocked Pargo before Allen split a pair of free throws to provide the final margin.
