The Cavaliers could move up to No. 2 if they beat Milwaukee and New Jersey beats Chicago tonight.
James added six assists in an all-around solid game and led a well-balanced Cavaliers attack that had six players score in double figures.
Joe Smith had 17 points and grabbed 13 rebounds for the Sixers. Willie Green scored 24 points, and Samuel Dalembert added 11 points and 10 rebounds.
WASHINGTON - The Magic overcame Antawn Jamison's 48 points and kept up a last-minute push to improve their playoff seeding.
Hedo Turkoglu scored 26 points to lead the Magic, who are sitting in eighth place in the Eastern Conference, but could move as high as seventh if they beat Miami tonight, the last day of the regular season.
If they do move up, it will be largely at the expense of the Wizards, who have lost eight of nine and six straight at home - most of them without their two injured All-Stars, Gilbert Arenas and Caron Butler.
AUBURN HILLS, Mich. - Richard Hamilton scored 10 first-half points in a glorified exhibition game for both teams.
Neither team had anything to play for - the Pistons are locked into the Eastern Conference's top seed and the Raptors will be No. 3 - but Detroit coach Flip Saunders didn't want a repeat of his team's feeble loss to Philadelphia.
So, while Toronto's Chris Bosh and Anthony Parker spent the night in street clothes, Detroit played its normal rotation until the game got out of hand.
Unfortunately for the Raptors, Morris Peterson was still on the floor in the final minutes when he appeared to hyperextend his right knee. He limped off the floor.
ATLANTA - The Hawks set season highs for points in a quarter and a half as they finished another disappointing season by beating the Pacers.
Atlanta missed the playoffs for the eighth straight season, but reached 30 wins for the first time since the 2002-03 season.
Tyronn Lue and Josh Smith each scored 25 points.
Backup forward Ike Diogu scored 20 for Indiana, which was eliminated from playoff contention Sunday for the first time in 10 years.
