Marlins starter Brad Hand was staked to a 3-0 first-inning lead, but couldn't hold on, dropping a decision to the Nationals on Sunday.
Hand couldn't make it out of the fifth, giving up eight hits and five runs in 4 2/3 innings to end a two-game losing streak and drop back to .500 at 4-4.
Hand labored through 80 pitches, striking out five and walking two, but was hit hard the second time through the lineup.
