DALLAS (AP) -- Harrison Barnes scored a career-high 34 points and the Dallas Mavericks won for the first time this season, beating the Milwaukee Bucks 86-75 in overtime Sunday night.
   Barnes, who left Golden State to sign a $94 million, four-year contract with Dallas in the offseason, has scored at least 30 points twice this season after hitting the mark only once in his four years with the Warriors.
   His 20-foot jumper opened the scoring in overtime, and the Mavericks (1-5) never trailed in the extra period.
   J.J. Barea added 21 points for Dallas, including five in overtime.
   Jabari Parker led Milwaukee with 16 points, but only two after halftime. Greg Monroe had 14 points and 11 rebounds for the Bucks, who had won three straight.
