CLEVELAND — LeBron James sent Toronto into summer vacation for the third straight season as the Cleveland Cavaliers completed a series sweep of the Raptors with a 128-93 win in Game 4 on Monday night to advance to the Eastern Conference finals.

James finished with 29 points, 11 assists and spent some of the final 7:38 dancing near the bench during Cleveland’s 10th straight playoff win over Toronto, which changed its system, its roster and its approach but still can’t beat the game’s best player.

Kevin Love added 23 points and J.R. Smith 15 for the Cavs, who can now rest while waiting for the Boston-Philadelphia semifinal series to end.

Jonas Valanciunas scored 18 and Kyle Lowry had 10 assists to lead the exasperated Raptors. Toronto’s frustration hit its peak late in the third when All-Star DeMar DeRozan was ejected for a flagrant foul.

76ers 103, Celtics 92

PHILADELPHIA — T.J. McConnell turned a surprise start into the save of the season and Dario Saric scored 25 points to help the 76ers stave off elimination in a win over the Celtics in Game 4.

The Sixers still face daunting odds headed into Game 5 and trailing 3-1 in the Eastern Conference semifinals: No NBA team has ever won a series down 3-0.

McConnell had a career-high 19 points, seven rebounds and five assists in only his second start of the season.
