It was the first victory for the Nets' franchise in Minnesota since 2002. Brooklyn won its third in a row and is 12-2 since P.J. Carlesimo became the team's interim coach.
Minnesota closed within two points early in the fourth period, but the Timberwolves hurt their cause by converting just 3-of-15 from 3-point range.
The Timberwolves, who have dropped three straight, were led by 15 points from Andrei Kirilenko and 14 from Dane Cunningham.
Minnesota, struggling without the services of the injured Kevin Love, has lost seven of its last eight.
