Rodrigue Beaubois finished for the Dallas Mavericks, a good sign for a team trying to get back on track while also preserving veterans like Jason Kidd. Beaubois made some acrobatic moves to keep balls in play and scored 19 points, including five straight in a clinching stretch early in the fourth quarter as the Mavericks got a desperately needed 107-98 victory over the Washington Wizards on Tuesday night.
