Griffin and Crawford's play got the sellout crowd on its feet roaring heading into a timeout.
"They would rather see Blake dunk than me any time of the day so I just have to figure out the best way to get it to him," Crawford said.
Griffin's assists were a career high and helped him record his first triple-double since he had two late in the 2010-11 season. He secured the triple-double by grabbing a miss by J.J. Redick with about six minutes left in the game, and checked out to a standing ovation with 3:55 remaining.
"He's doing everything. He's finding people, he's making plays," Crawford said of Griffin. "He demands a lot of attention down there, so he's getting double-teamed and kicking out to our shooters. He's making the right play all of the time."
Barnes made six 3s in helping the Clippers go 12 of 29 from long-range and complete a season sweep of the Bucks.
"We've been a team that's been able to hang around with other teams and then suddenly find something in the fourth quarter, but not tonight," Bucks coach Jim Boylan said.
The Clippers led by 15 points in the second quarter, thanks to a 16-2 run that included two 3s by Barnes and one by Chauncey Billups. Both teams shot better than 50 percent in the half, and the Clippers finished at 54 percent for the game.
NOTES: Bucks C Larry Sanders didn't record a block, ending a streak of 40 consecutive games in which he had at least one, the longest active run in the NBA. ... Green Bay QB Aaron Rodgers sat courtside next to Clippers owner Donald Sterling. ... The Bucks' streak began with wins at Dallas and Houston, and their previous two came in overtime.
