Ersan Ilyasova had 20 points and Brandon Knight 18 for the Bucks.
"(The Warriors) have a lot of weapons and can beat you in a number of ways," Bucks coach Larry Drew said. "I thought we did some good things, but we didn't do it for the duration of the game. We had too many breakdowns, too many lapses and our margin for error is very small."
Drew said he implored his team to play with high energy to start the second half, to no avail.
"We came out and were flat-lined. They got on a good run and we just couldn't overcome the deficit," Drew said.
Energetic play needs to be a team goal, Knight said.
"It has to be all five guys that are on the court," he said. "We have to have everybody playing with as much energy as we can."
Milwaukee grabbed a 30-28 lead after the first quarter, sparked by Knight's 10 points.
Golden State opened the second quarter on a 10-0 run and went on to a 50-48 lead at the half. Golden State shot 55 percent from the field in the half, despite connecting on only 4 of 14 3-point attempts.
Knight had 13 first-half points for the Bucks and Ilyasova added 12.
