Returning to their home ballpark, the Washington Nationals were unable to maintain the momentum that helped them to a winning four-and-two record during last week’s road trip. The NL leading Pittsburg Pirates swept the Nats by a combined score of 22-4 in the doubleheader. But less than 24 hours after getting pummeled the night before, the Nationals came out flying in the series finale on Sunday. The Nationals turned the table and outhit Pittsburgh 15-6. All the Nats runs came in the first three innings and every Nat in the lineup recorded a hit. Josiah Gray won it for Washington with another quality outing.
