Antetokounmpo had 21 points and 16 rebounds in 35 minutes, Khris Middleton adding 18 points and seven assists in 36 minutes.
The Bucks were outscored by 27 points in the 4th quarter, the biggest differential in a fourth quarter of a playoff game in the time of the shot clock.
The Bucks are down 3-0 in the series.
Mike Budenholzer said 36 minutes was as much as he wanted to play his two-star despite the deficit.
“No, I think we, obviously, it’s 48 minutes. You gotta be good for the last 12. If anything, I think I keep us fresh and ready to go and compete and all of that stuff. Khris was in a bit of a problem foul. It is a high standard. If you go as hard as these guys in a playoff game, 35-36 [minutes], I think this pushes the ceiling. ”
