Budinger, who has been the Timberwolves' leading scorer in the preseason since All-Star forward Kevin Love broke his hand, hit four 3-pointers and scored 12 third-quarter points.
The Timberwolves took a 24-15 first-quarter lead after going 3 for 4 from 3-point range. The advantage grew to 35-18 in the second quarter when the Timberwolves, who shot 56 percent from the floor in the opening half, went on a 9-0 run before taking a 48-36 lead into halftime.
The Bucks went on a 10-2 run in the third quarter to close the gap to 13. However, the Timberwolves answered with nine of the next 11 points to put the game out of reach.
