Clayton Kershaw tied Sandy Koufax's franchise record of six straight 200-strikeout seasons while tossing eight scoreless innings, and the NL West-leading Los Angeles Dodgers defeated the Washington Nationals 3-0 Wednesday night. Kershaw (10-6) took a perfect game bid into the sixth inning, when Michael Taylor doubled to deep center field. Kershaw retired the next two batters on grounders to end the inning.
