DALLAS (AP) — Taj Gibson had 20 points and 15 rebounds, Mike Dunleavy hit a go-ahead 3-pointer and the Chicago Bulls overtook the Dallas Mavericks in the fourth quarter of a 100-91 victory Friday night.
The Mavericks led by 16 in the first half and had erased a six-point Chicago edge when Dunleavy put the Bulls back in front and started a 10-0 run with a 3-pointer for an 87-85 lead.
Jimmy Butler had 19 points, seven rebounds and a big block during the decisive spurt, and Kirk Hinrich scored 17. Dunleavy finished with 16 points and eight rebounds, shooting 4 of 7 from long range.
Monta Ellis scored 20 to the lead the Mavericks, who were trying to match their season high with a fifth straight win. Dirk Nowitzki had 15.
The Bulls won for the eighth time in nine games and answered a 22-point home loss to Dallas in December.
Gibson followed Dunleavy's go-ahead 3 with a dunk on an assist from Joakim Noah, who then blocked a shot by Sam Dalembert on the other end right after committing his fifth foul.
Butler scored inside after Ellis fell down, and after two more Dallas possessions ended in misses, Hinrich hit a pull-up jumper for a 93-85 lead. Butler then blocked a layup try by Jose Calderon and made a free throw at the other end to complete the run as the Bulls outscored the Mavericks 27-15 in the fourth.
After the Bulls went up 84-78 on back-to-back 3-pointers from D.J. Augustin and Hinrich, the Mavericks went back in front with a 7-0 run started when Nowitzki hit a one-legged fadeaway over Noah after Noah had stolen the ball from him two straight times.
Noah didn't have a point or rebound in the first half but finished with 10 points and nine boards. The team's assist leader had four more of those.
The Bulls took their first lead on a reverse layup by Carlos Boozer with 2:48 left in the third quarter, but didn't score the rest of the period. Shawn Marion quickly answered with a layup, and DeJuan Blair ended a 2½-minute scoreless stretch with a bucket to put Dallas up 76-73 going into the fourth.
