The Dallas Mavericks finally have a win over one of the top four teams headed to the Western Conference playoffs -- just in time for their own postseason push. Dirk Nowitzki had a season-high 33 points, including the first eight for Dallas in overtime, and the Mavericks moved within a game of .500 for the first time since mid-December with a 109-102 victory against the Los Angeles Clippers on Tuesday night.
