He ended that streak by going 10-of-19 from the field and making 14-of-18 from the foul line. He also grabbed 13 rebounds in boosting the Timberwolves to their fourth win in six games.

Luke Ridnour added 12 points for the Timberwolves, who went to the free throw line 35 times compared with just nine attempts for the Cavaliers.
