In their first game after a pair of deadline trades brought in four new players, Chicago won for the fifth time in six outings. Hinrich grabbed eight rebounds and Luol Deng added 18 points in the Bulls' win.
Key baskets by Hinrich and Flip Murray -- acquired Thursday from Milwaukee -- allowed the Bulls to stretch a one-point lead at the start of the final quarter to a five-point margin.
Chicago then went on an 8-1 run to put the game away at 91-80 with less than seven minutes left.
The Timberwolves, who lost their fifth straight game, were led by Corey Brewer with 19 points and Jonny Flynn with 14.
