The Marlins do not look like a team that will roll over on you and just die. However, almost all of their players are very green and as such make some pretty stupid errors. Dontrelle did all he could to win this game, but he can't hit for everybody.
However, this was not a bad game for the Marlins. The pitchers after Dontrelle only allowed 1 run. If anything, I'd be concerned as an Astro fan that they didn't hit off a bunch of AA and AAA pitchers.
So at this point I see the Marlins as a pesky yet extremely beatable team. You can't let your gaurd down, but the Mets should be able to beat this team into the ground.
I'd watch out for this team in about 2 years. If they stay in Florida and the NL east.
