LeBron stops the rot as Cavs hold off Raptors
LeBron James scored 34 points as the Cleveland Cavaliers snapped their three-game losing streak with a battling 116-112 win over the Toronto Raptors.
The Cavs had looked to be easing to victory after opening up a 15-point lead in the fourth quarter.
But a determined Raptors fightback, which saw them move to within four with two seconds left, ensured the game went down to the wire after Kyle Lowry's three free throws.
Kyrie Irving meanwhile scored 24 points and Channing Frye contributed 10 off the bench for Cleveland.
DeMar DeRozan topped Toronto's scorers with 31 points while Lowry finished with 24 points and nine assists.
The win saw the Cavaliers improve to 14-5 in the overall Eastern Conference race, ahead of Toronto (14-7) and Boston (12-9).
