Juan Rivera knocked in four runs with a pair of doubles in the Dodgers' 7-4 win over the Nationals on Thursday. Rivera supplied all of the offense in the first eight innings, but it was Tony Gwynn Jr. who broke a tie with a two-run double in the ninth, giving the Dodgers a 6-4 lead. Rivera figured to be staring at less playing time down the stretch with Jerry Sands up, but now that Andre Ethier has been ruled out for the rest of the month, it's a good bet that Rivera will be in there most days.
