Absolutely but even bad teams can win a series at home (and the Reds were playing something like .700 baseball for a month, while the Dbacks aren't bad). And as bad as the Mets game was it doesn't matter more than if they'd lost it 5-0. Suarez gave them no chance and they won the next game an hour later.
I'm not making an excuse, it's more like a warning. If it's not a normal lull, it's because we're a bad road team and will not win enough remaining road games to make the playoffs. At least they finish at home if they can survive the 7 games in Atlanta and Colorado (but a lot of work to do before then obviously).
