The Marlins just seem to have the Nationals’ number. At least that’s our conclusion after last night.

Even though the Nats had won 5 straight going into Monday, no one could be much surprised when the D-Train ran them over, 9-4. But getting laid low 6-3 by pitcher Brian Moehler, who hadn’t notched a major league win in two years? That’s gotta hurt.

Two Saturdays ago, the Nats did manage to beat the Marlins, albeit in a 10-inning 3-2 squeaker. What gives?

Manager Frank Robinson knows what gives: “I have to figure out some way for us to put runs on the board, especially early in the game. Let’s get out of this thing before it becomes a problem, a nuisance, before somebody hits the panic button.” If anybody knows what this “some way” is, let us know and we’ll pass it along. And someone, hide that button.

If there’s any consolation in all this, it’s that Jose Vidro’s homer in the seventh on Monday ended ace Dontrelle Willis’ stretch 24 scoreless innings — which is fitting, as it began when he shut out the Nats on April 8.

But that’s negative consolation. Any positives? Well, Nats shortstop Cristian Guzman did halt his season-opening batting slump, or at least un-slumped a bit. On Monday he was 0-for-3, which brought his batting average down to .106. But last night he went 3-for-4 and boosted that average .051 higher than it was before. Congratulations, man. We’d hate to see you busted down to the minors just as we remembered that you don’t have a letter ‘h’ in your name.

Coming up tonight: the first in a two-game series against the Atlanta Braves to close out the Nationals’ first homestand.
