We were totally out of sync, both on the offensive and the defensive ends," said Sixers coach Tony DiLeo. "We just can't get in sync defensively with our rotations."

The Raptors shot 53.8 percent from the field. That's the kind of number that will ensure a quick exit from the postseason.

"Defensively, we haven't been able to step up," said swingman Andre Iguodala.

The Sixers attribute some of their troubles to starting power forward Thaddeus Young's sprained ankle, which has kept him out of the last seven games, but it appears there's more to it than that. The Sixers won the first two before hitting a five-game slide.

"You never want to go on a losing streak at this time in the season, but it is happening," said guard Andre Miller.

The Sixers close out the regular season against the East's top two teams -- Tuesday at home against the Celtics and Wednesday at Cleveland. Those two have clinched the first and second spots, so perhaps the Sixers can catch a break if they don't play their top guys as much as usual. However, the Cavs can tie the 1985-86 Celtics for the best home record in league history (40-1) by beating the Sixers.

RAPTORS 111, SIXERS 104: The Sixers lost their season-high fifth in a row despite holding a 47-34 rebounding edge, including a 22-11 advantage on the offensive glass. They cannot finish higher than sixth in the Eastern Conference, meaning they'll have to play Orlando, Boston or Cleveland, and won't face fourth-seeded Atlanta, which would seem to offer their best chance to advance. Toronto blocked 10 of the Sixers' shots, including four of Reggie Evans'.

Lou Williams paced the Sixers (40-40) with 23 points. Andre Iguodala added 21 and Samuel Dalembert contributed 18 points and 12 rebounds.
