In the decisive third quarter, the Sixers forced five turnovers, hit half their 22 shots, including four three-pointers, and opened the lead to 14 points.
The Sixers, who were without swingman Evan Turner due to a right thigh contusion, again got balanced scoring, led by Jrue Holiday's 24 points and five assists. Andre Iguodala collected 21 points, seven rebounds and four assists while Lou Williams came off the bench to contribute 17. Center Spencer Hawes, who said before the game that his strained back was feeling much better, picked up his sixth double-double of the season with 11 points and 10 boards.
Before the game it was announced that Iguodala was among 20 finalists for the 2012 U.S. Olympic team. The final roster will compete in London this summer.
Iguodala was a starter for the team and coach Mike Krzyzewski at the World Championships that took the gold in 2010 in Turkey.
"I think Dre's got a great chance, if he stays healthy," said Sixers coach Doug Collins of Iguodala making the 12-man roster. "When he was trying out for the team last time for the World Championships, my son Chris was working with the team and he relayed to me that (Krzyzewski) needed Dre to be their best on-ball defender and get that starting group a guy that they could put on whoever they have to put on defensively to take somebody out of the game. I think that's his calling card, that he can guard multiple guys, he can lock in and bring that to them. I think he did that with the World Championship team."
Milwaukee (4-8), which dropped its eighth straight on the road, was led by Andrew Bogut's 20 points and 11 rebounds.
