Miami, FL (SportsNetwork.com) - Mike Dunleavy scored 19 of his 22 points in the third quarter and the Chicago Bulls beat the Miami Heat 93-75 on Sunday.
Jimmy Butler added 17 points and Taj Gibson scored 15 with nine rebounds for the Central Division-leading Bulls, who have won three in a row and six of their last eight games.
Derrick Rose had 14 points two days after pouring in a season-high 31 in a win over Portland, the first time the oft-injured former MVP topped 30 since March 12, 2012.
Former Bull Luol Deng led Miami with 17 points and 10 rebounds and Dwyane Wade also scored 17.
After holding the Heat under 30 percent shooting for a seven-point lead at halftime, the Bulls pulled away with a big third quarter.
Dunleavy's 19 points came on eight shots, including a trio of 3s. He missed just once from the field and made both of his free throws.
"Every night it can be someone different," said Rose.
Butler had eight points in the quarter and Gibson scored the other six. One of Dunleavy's 3s stretched Chicago's lead to 26 points near the end of the quarter and it was never closer than 15 the rest of the way.
"It was a tough second half," said Heat coach Erik Spoelstra. "We came out flat. That was pretty clear."
Heat center Chris Bosh (calf) missed a game for the first time this season and the Bulls took advantage early on, scoring mostly in the paint.
Consecutive dunks by Gibson to open the game sparked a 10-2 run for the Bulls, who then scored just four points over the next nine-plus minutes as the Heat built a 20-14 lead early in the second quarter.
But back-to-back 3s and eight straight points by Aaron Brooks started a 14-2 Bulls flurry that gave the visitors a 28-22 lead and they remained in front for the rest of the game.
