Derek Hill drives in the go-ahead run with a seventh-inning grand slam as the Philadelphia Phillies defeat the Washington Nationals 6-3 on Monday night. Hill’s three-run burst breaks the game open, giving Philadelphia the lead and momentum after the Phillies earlier made a notable roster move. Bryce Harper then adds offense with a two-run home run, extending the Phillies’ advantage. The grand slam comes off Nationals reliever Tom Cosgrove, who is charged with the loss in the matchup. Hill also contributes in the field, making a running, tumbling catch in right-center in the eighth inning. Earlier in the day, Philadelphia completes a trade acquiring Luis Arraez from the San Francisco Giants, a move referenced in reporting from the game. With the win, the Phillies continue a streak, recording their third straight victory. The combined scoring from Hill and Harper delivers the final margin of 6-3 for Philadelphia over Washington.
