It was the Dodgers’ 13th shutout of the season. The NL West leaders won their fourth in a row overall and fifth straight at home. They outscored the D-backs 23-5 in the series. Freeman hit his MLB-leading 51st double in the fourth, leaving him one shy of tying Johnny Frederick for most in franchise history. Betts singled in the first and third innings. Freeman’s 25th homer was a 440-foot shot to right, the third-longest homer for the Dodgers this season.
