ST. LOUIS (AP) — Rookie Zach LaVine scored all six of his points in the final five minutes, helping the Minnesota Timberwolves erase a 13-point deficit midway through the fourth quarter and close the preseason with a 113-112 victory over the Chicago Bulls on Friday night. Two free throws by LaVine made it 113-109 with 4.2 seconds to go and the Timberwolves survived when Thaddeus Young missed a pair with one second left and Mike Dunleavy missed a desperation heave.
