CHICAGO -- Guard Jimmy Butler scored a game-high 31 points with nine rebounds to lead the Chicago Bulls to a 91-82 win against the Milwaukee Bucks on Monday night in Game 2 of their Eastern Conference quarterfinal playoff series.

Bulls guard Derrick Rose added 15 points and nine assists after being held scoreless in the first half. Chicago seized a 2-0 lead in the best-of-seven series.

Guard Khris Middleton led Milwaukee with 22 points. Guard Michael Carter-Williams added 12 points for the Bucks, who were outscored 20-8 to finish the game.

After the Bulls fell behind 74-71 early in the fourth quarter, Butler took control. He scored 14 points in the fourth quarter, including nine points during a 13-0 run that put Chicago up by 10.

Butler kissed his hand and pointed toward the sky after hitting a 3-pointer over Milwaukee guard O.J. Mayo to tie the score at 74 with 9:02 remaining in the fourth quarter. Two minutes later, he drove past Middleton and leaped for an emphatic dunk over Bucks center Zaza Pachulia to give the Bulls an 80-74 edge.

A deep 3-pointer by Bulls guard Aaron Brooks gave the Bulls a 71-68 lead after the third quarter. Milwaukee stayed close thanks to eight points in seven minutes from Middleton.

Chicago rallied for a 39-38 halftime advantage after trailing by as many as nine points in the second quarter. Forward Nikola Mirotic came off the bench to score Chicago's final seven points of the half, including a turnaround hook shot with one second remaining to take the lead.

Milwaukee led 16-11 after a sloppy first quarter in which both teams combined to shoot 24.4 percent (11 of 45).

A brief skirmish stopped play with 8:53 to go in the second quarter. Brooks took exception to Bucks forward John Henson standing over him after a collision and quickly leaped to his feet. Players from both sides converged to scream at one another, which resulted in technical fouls to Henson, Mayo, Butler and Bulls center Joakim Noah.

Pachulia was ejected after receiving his second technical foul with 2:48 remaining in the fourth quarter. Mirotic also drew a technical foul during the sequence.
