Having already used a chunk of his bullpen during a game that spanned two days, Dodgers manager Don Mattingly passed on setting up a lefty vs. lefty matchup in the late innings. The Washington Nationals took advantage. Pinch-hitter Matt den Dekker lined a two-run, tiebreaking homer in the eighth that lifted the Nationals over Los Angeles 5-3 on Saturday, completing a game suspended a day earlier after the fifth because of a lighting malfunction.
