Barnes and John Lucas tangled on the baseline and were called for double technicals after Crawford missed a 3-pointer. Referees dragged Barnes away and both players were ejected, bringing Butler back in.
"They locked in on defense and we stopped moving the ball from side to side, which was the key for us in the first three quarters," said Andrea Bargnani, who had 12 points for the Raptors. "They ran the floor, which is what they do, and we let them do that."
Los Angeles led for much of a back-and-forth third, with its biggest margin of six points coming on a basket by Paul. The Raptors got timely 3-pointers from Kleiza and DeRozan, who had 11 points in the period. The Clippers were 9 of 15 from the free throw line.
"That's one of the most talented teams in the league, but I thought our defense was on par in the first half until the middle part of the third quarter, when I thought it went south," Raptors coach Dwane Casey said. "We knew it was a matter of time before Crawford and those guys were going to get going, so we wanted to make it tough on them. We did, but you've got to do it for 48 minutes."
The Clippers' second unit sparked a 15-11 stretch to start the second quarter and extend their lead to 40-32. Griffin, Paul and Jordan then returned only to be outscored 15-4, and Toronto carried a 47-44 advantage into halftime. The Clippers shot just 36 percent in the half, when their largest lead was eight.
Los Angeles opened the game by outscoring the Raptors 17-10, but Toronto closed within four by the end of the first quarter.
