The Bucks got within 68-65 to end the third, but then came the run that Miami had been waiting for all evening.
Both teams got a big scare with 6:59 left. Battier drove for a layup from the right wing, and Sanders rushed down the middle of the lane to attempt a block. A collision ensued and both players hit the court awkwardly, Battier hitting his head on the hardwood and Sanders - who fell over Battier - grabbing at his right leg.
Battier made two free throws, then departed for the Heat locker room to get stitches on his chin.
"We held court," Spoelstra said. "We protected it for two games. We did what we're supposed to do. And that's it."
NOTES: It's the 11th time the Heat have gone up 2-0 in a playoff series. They're 10-0 in the previous instances. ... Milwaukee has lost 21 of its last 29 playoff games. ... Sanders was third in the NBA's Most Improved Player voting, behind Indiana's Paul George and New Orleans' Greivis Vasquez. "Look where he was last year and where he is today. The improvement is very obvious," said Boylan, who thought Sanders should have won. ... Jennings was held without a first-half basket for only the fifth time all season.
