Clayton Kershaw allowed only an unearned run in eight innings to become the first 16-game winner in the majors, and the Los Angeles Dodgers beat the Arizona Diamondbacks 3-1 on Wednesday night. Kershaw (16-3) allowed six hits, retiring 12 of the final 13 batters he faced, seven by strikeout, to improve to 13-1 in his last 16 starts. Scott Van Slyke hit a solo home run off Wade Miley (7-10) before leaving the game with an ankle injury in the fourth inning. Matt Kemp had a two-run double.
