The AP reports: Dirk Nowitzki and Brandon Bass each scored 17 points to lead the Dallas Mavericks to a 108-82 victory over the injury-depleted Washington Wizards on Tuesday night in the preseason opener for both teams. Wizards forward Antawn Jamison left in the first quarter with a right knee injury and did not return… Andray Blatche’s 18 points paced the Wizards. Dallas’ Josh Howard, who finished with 15 points, was greeted by a mixture of cheers and boos from the crowd when he was introduced with the starting lineup following a controversy-filled offseason.
