The defense was holding the Bulls in check, and the Milwaukee Bucks led 74-71 early in the fourth quarter.
Then All-Star Jimmy Butler and his Chicago teammates put it all together, ran off a 13-0 run, and seized Game 2 with a 91-82 victory. The Bulls now lead the best-of-seven series two-games-to-none.
Butler, a Marquette product, scored 14 of his playoff career-high 31 points in the fourth quarter. Derrick Rose scored all of his 15 points after halftime.
Khris Middleton led the Bucks for a second consecutive game, tallying 22 points. Michael Carter-Williams added 12.
In an extremely physical game, the two Central Division rivals combined for seven technical fouls, two of which led to the ejection of center Zaza Pachulia with 2:48 remaining in the game. There were several occasions when members of both teams became involved in pushing and shoving.
Milwaukee, which shot 35% from the field and was outrebounded by 16, has lost eight straight postseason games dating back to 2010.
